How to video – Backup Camera Installation

Start to finish, fully detailed!

As part 3 of our series on how to install a backup camera we take you through the entire installation process.

Our equipment and installation locations

For our installation, we decided that the back up camera would be located in the rear tailgate and the monitor would be a replacement rearview mirror monitor. The camera we decided on was the Boyo VTK230HD back up camera as it was very small and would mount perfectly to the lip overhang by the license plate.

Here we mounted the backup camera near the license plate on the overhang above the license plate

For the monitor, we opted to use the Safesight RVMZH4300 4.3 glass mount rearview mirror monitor.

Why add a back up camera?

The Toyota Sienna minivan is a relatively large vehicle that has multiple blindspots. For most drivers vans and SUV’s are the most difficult vehicles to back up, let alone see something small such as a child or toy directly below the rear bumper. This makes them very prone to hitting objects that you cannot directly see. A back up camera eliminates this risk.

It’s to easy to run things over behind your vehicle.

Why is this installation more difficult?

Opening tailgates present a unique problem; the wiring must be installed in a way that allows the tailgate to continue to function normally. If unfamiliar, the installation is difficult, we show you how to make the installation a breeze.

Step 1 – Equipment Placement
You will need to find a location to mount the control bow and route the wires. The location that we determined would be the best is under the seat.

Step 2 – Remove the seat back for running wires
The plastic seatback is removed to make way for running the wires in the seat for connection to the control box. Simply pop the pops and slide the seat back down for removal.

Step 3 – Remove the original headrests and insert the AV7950
The removal of the factory headrests is simply a matter of pulling them out through the top. When inserting the replacement headrests you will need to route the wiring.

Step 4 – Routing the wire through to the seat bottom
The wiring is run on the left and right side of the seat back to seat bottom connector bracket. The are factory cables that are run and we run ours the same way.

Step 5 – Tie off cabling
The cabling must be secured to prevent cable damage when the seat is moved. All of our cables are tied to the existing factory cables.

Step 6 – Prepare seat back for re-installation
Make sure to have the plastic tabs in place so that they are aligned for the re-installation of the seat back.

Step 7 – Route drivers side wiring to control box
To run the drivers side cabling we attach all of the cables underneath the seat to the factory cables. Once completed we make the connection to the control box.

Step 8 – Power connection
To provide power to the system we connected our power lead to the Bluetooth module behind the rear cigarette lighter plug.

Step 9 – Passenger side cabling
To run the passenger side cabling we opted to remove the center console and route the wiring through the console. Once completed we make the connection to the control box.

Step 10 – Verify our connections with a voltmeter
Before turning on the power we verify our connections with a volt meter

Hopefully this video gives you a better idea as to how we install a set of replacement headrests in your vehicle.

Backup Camera System Installation Guide

Trigger wire based systems

The easiest way to understand how a standard backup camera system is installed is by understanding the components. Most back up cameras and systems have similar components. This particular guide is designated for backup camera systems with trigger wires. A backup camera system can be broken down into five basic components (See picture above).

The Monitor, (A1): Some monitors like the one shown above will only have a single cable coming out of the monitor but don’t be alarmed as this single lead cable usually connects to a power harness that possesses all of the video inputs and power connections

The Power Harness, (A2): The monitor will come with a power harness that will attach to the single cable coming out of the monitor. This particular monitor has several connections:

  • 2 – Yellow RCA video inputs
  • 1 – Left and right audio input (white and red RCA)
  • 1 – Red bare wire or positive power lead will which connects to 12 volts power
  • 1 – Black bare wire that is the ground connection
  • 1 – Trigger wire (usually green or blue)

When 12 volts is applied to this wire the monitor automatically turns on and selects the back up camera input. This connection is made to the positive side of the reverse light.

The Camera, (A3): The camera is very similar to the monitor in that it will have a yellow RCA video plug and a single cable with a DC power plug input for power.

The Power Harness, (A4): The camera should include a male DC power connector to bare power leads. This DC power connector will have a Red 12 volt power lead and black ground lead. In most cases the center inner female pin is 12 volts power and the outer shield is ground.

The RCA Cable, (A5): Last but not least is the single yellow RCA video cable that is included with camera. Its sole purpose is to take the video feed from the camera and display it in the monitor.

Note 1: This cable is usually 18-25 ft long and in some cases has bare red lead as part of the cable. This lead is a raw lead that can be used for a couple of purposes. Imagine this red wire is a single wire tapped the entire length of the RCA cable and can be used to send the reverse trigger signal to the front of the vehicle. The red lead can also be used in some installations to continuously power the camera if you want your system always on with the vehicle.

Note 2: It is important to remember during the installation process that yellow inputs are used exclusively for the video signal, whereas black and red inputs are used exclusively for power.

Note 3: Just because a monitor does not have a trigger wire does not mean it can only be turned on manually. Most monitors do not have a trigger wire because they posses what is known as a video sense feature and will turn on automatically as soon as they sense a video feed. We demonstrate that installation process in a separate section below

5 – Step Installation Process (Trigger wire based)

Step 1: Connect the power harness (A2) into the monitor’s designated power input.

Back up monitor cable connections
Monitor power cable connections

Step 2: Draw power to the monitor by connecting the red wire to 12 volt power and the black to ground. Power to the monitor is usually drawn at the fuse box. The trigger wire determines the operation of the monitor. The default installation is to connect this to the positive side of the reverse light. By doing so, the monitor will automatically turn on with the vehicle is placed in reverse. For manual operation you will leave this disconnected. This can also be connected to a source that turns on with the key and the monitor will remain on until the vehicle is shut down, perfect for commercial vehicles.

Step 3: Connect the male power harness (A4) into the camera’s female power input.

Step 4: Draw power to the camera by connecting the red wire to 12 volt power or the positive side of the reverse lights and the black to ground.

Step 5: Now that the monitor is drawing power at the fuse box and the camera is drawing power directly at the reverse tail light, all you need to do is connect the camera to the monitor using the standard yellow RCA cable (A5) ***If the yellow RCA cable has two red power wires on each end, please read Note 1 above.

Back up camera RCA connections

At this point you should have all the connections made and a working system is a key turn away. Makes sure to button up and tape all connections and you should be all set.

Video sense based systems

Back up monitor cable connections
Monitor power cable connections

Again the easiest way to understand how to install a video sense backup camera system is by understanding the components. A backup camera system can be broken down into five basic components (See picture above).

The Monitor (A1): The monitor will come with a pigtail that will have video inputs, these are RCA cables with yellow, white and red (sometimes two yellow) jackets. In this case the yellow and white are video inputs just like what you would find in a home television, and the red is the power input connector.

Monitor Power Harness (A2): The monitor will come with a power harness that will attach to the red (sometimes black) DC power connector input on the monitor. On the opposite end of the power harness will be two wires; the red wire will always be used for positive power and the black wire will go to ground.

The Camera, (A3): The camera usually is a little different from the monitor in that it includes a two part harness (A4). This is so that you can mount the camera in a weather proof fashion and do so without drilling an excessively large hole. A two part harness is comprised of the pigtail and the camera cable. The pigtail will have a yellow video output plug and a red (sometimes black) dc power connector for power.

Camera Power Harness (A4): The camera should include a male DC power connector to bare power leads. This DC power connector will have a Red 12 volt power lead and black ground lead. In most cases the center inner female pin is 12 volts power and the outer shield is ground.

The RCA Cable (A5): Last but not least is the single yellow RCA video cable that is included with camera. Its sole purpose is to take the video feed from the camera and display it in the monitor.

**It is important to remember during the installation process that yellow and white inputs are used exclusively for the video signal, whereas black and red inputs are used exclusively for power.

Note 1: This cable is usually 18-25 ft long and in some cases has bare red lead as part of the cable. This lead is a raw lead that can be used for a couple of purposes. Imagine this red wire is a single wire tapped the entire length of the RCA cable and can be used to send the reverse trigger signal to the front of the vehicle. The red lead can also be used in some installations to continuously power the camera if you want your system always on with the vehicle.

Note 2: It is important to remember during the installation process that yellow inputs are used exclusively for the video signal, whereas black and red inputs are used exclusively for power.

5 – Step Installation Process (Video signal sense based)

Step 1: Connect the DC power harness (A2) into the monitors designated power input.

Back up monitor video input and power connectors

Step 2: Connect power to the monitor by attaching the red wire to 12 volt power and the black to ground. Power to the monitor is usually drawn at the fuse box

Monitor DC power connector

Step 3: Connect the camera power and video pigtail (A4) into the cameras connector. The pigtail provides power to the camera and the video output to the monitor.

Back up camera power leads

Step 4: Connect power to the camera by attaching the red wire to 12 volt power and the black to ground. Power to the camera is usually drawn directly at the reverse tail light. With video sense systems, anytime there is power to the camera the montitor will be turn on automatically.

Back up camera dc power connector leads

Step 5: Now that the monitor is drawing power at the fuse box and the camera is drawing power directly at the reverse tail light all you need to do is connect both systems using the standard yellow RCA cable (A5).
***If the yellow RCA cable has two red power wires on each end, we advise that you disregard their use as they are not needed for this type of installation.

Car Amplifier Installation – Learn how


Why do I need a car amplifier

It is rather enjoyable to listen to music while driving your vehicle. But bad sounding tunes isn’t fun, instead of using your stock stereo and amplifier it’s better that you install a new amplifier to power up your speakers or subwoofer. Aftermarket speakers and factory speaker benefit greatly from additional power. The question is – Where do you start once you purchased your car amplifier?

Amplifier Installation Know How

First, you need to find a suitable location for your newly bought amplifier. We suggest you place the amplifier underneath the seat or in a cargo area. Dissapation of heat is improtant and should be considered when mounting an amplifier.

For the amplifier’s wiring, you should consider buying the proper gauge power cable, a shielded RCA signal cable, 3 feet of ground cable that has the same thickness as the power cable, a ‘remote on’ wire, and a 12-16 gauge speaker wire for the main speakers. 

Next, you’ll need to get your tools ready for the job at hand. This would include things like:

Before you get started you will need to determine if you are going to use a line output converter or if you are making a direct connection to the aftermarket car stereo. Once you have determined where you are going to get your audio signal you may need instructions for taking of your vehicle’s dashboard apart. In actual fact, you should only remove the head unit of your vehicle’s dashboard as it is needed for hooking the the remote turn on and RCA cables.

With that out of the way, it is time for installing your amplifier. For your safety please ensure that nothing is connected to an electric current before you start.

car amplifier installation
Learn how to install a car amplifier.


Steps for installing the amplifier:

  1. You will start by disconnecting your vehicle’s negative cable from the battery.
  2. Then take the positive (red) power cable and attach it to the battery terminal on the positive side of your vehicle’s battery. Within 18 inches of the main battery connection you will install a fuse holder. The fuse is designed to protect the wire from melting and causing a fire if a short occurs.
  3. Now its simply a case of running the power cable through the vehicle’s firewall and to the amplifier. Care should be taken as to where run the wire. Do not run the power cables too close to speaker signal or wires.
  4. From here, you need make use of a metal screw or stud in order to connect the negative or ground cable. It’s important ensure the distance is not more than 3 feet as this could cause issues.
  5. Next, you will unscrew the bolt, clean the surface using sandpaper or a wire brush. Use a ring terminal to attach the ground wire, then fasten the screw or stud again. We recommend using a factory ground point and not a screw.
  6. Now you simply need to run the RCA cables down the opposite side of the vehicle to prevent noise. You’ll connect the RCA cables to a line output converter or to an aftermarket car stereo and to the amplifier.
  7. The next connection is the remote turn-on This connection is used to turn on the amplifier. This connection is easily made to an aftermarket stereo. If using a factory radio you will need to locate a circuit that has 12 volts when the key is in accessory position.
    The wire is typically run with the power wire to the radio location.
  8. From there you will need to run your speaker wires. We recommend that you crimp-on female spade connectors for every connection as this prevent stray strands of wire and shorts.

Before you close everything up

Before putting everything back together we recommend that you you go through your checklist to ensure that everything is in working order.

There you have it. Your amplifier is installed and ready to use.

Overhead DVD player in a 2011 Toyota Sienna with Dual sunroofs

Dual Sunroofs with an overhead DVD player

We receive many phone call with concerned customers after they have purchased an overhead dvd player and not remembering that they have a sunroof only to be told by an installer that they cannot use an overhead monitor.

What’s possible?

At Quality Mobile Video we have some of the best installers available and with a little imagination we show you what can be done in a vehicle with dual sunroofs. Today we installed a Gryphon Mobile MV-RF121DVD Overhead DVD player in a 2011 Toyota Sienna with dual sunroofs. This installation was a little more tricky, with the narrow sliver of roof that was available for mounting we had to make sure that we had a large enough foot print to mount the monitor. We used plate steel to make a bracket that would be strong enough to attach the screen. Other that that the installation was exactly the same as any other overhead dvd player installation.

Color to match

The interior of this Toyota Sienna was grey so we chose the grey version of this overhead dvd player to perfectly match this vehicles interior. This monitor is available in three colors unlike some other models that have snap on trims.

Power source

We ran all of the cabling down the A-pillar and were able to grab 12 volts from the factory fuse box located underneath the dash. The Toyota Sienna is a large van with plenty of power and adding this monitor to the vehicle electrical system was no problem.

Subwoofer Impedance and amplifier output

Car Subwoofer Packages

Car Amplifiers

Pioneer TS-SWX2502 Shallow Car Subwoofer system

Ohms law

Pioneer Subwoofer voice-coil DC resistance test

In electrical circuits there are two concepts. These concepts have a mathematical relationship between them.

I’ll use plumbing terms as it is easier to visualize these concepts using a pipe. The first is the voltage, in plumbing terms, voltage is the size of the pipe. The other is current or flow, in plumbing terms this is the pressure. These two concepts define the work or wattage.

Ohms law: V= I x R

V = Voltage
I = Current; measured in Milli-amps or Amps
R = Resistance; measured in Ohms

Using this concept and amplifier that outputs 400 watts at 4 Ohms will output 800 watts at 2 Ohms.

Speakers or Sub-woofers

Pioneer subwoofer voice coil cut away

Sub-woofers and speakers have a voice-coil; it is the heart or the device that performs the work. A voice-coil is a tightly wound copper wire that when electricity is applied, generates a magnetic field that either attracts or repels a closely mounted magnet.

When electricity is is moved through this copper wire it does so with resistance (known as Impedance), this resistance is measured in Ohms. The lower a speakers impedance, the easier it is drive.

Amplifier output relationship to Impedance

Amplifiers have a sweet spot in their relationship to output and impedance. Problems arise when a sub-woofer has very low impedance or resistance. The output of an amplifier is measured in wattage or work, work has a byproduct called heat. Excessive heat causes and amplifier to shut down to protect itself from destruction. Heat is the largest factor in the life span of electronics.

Consideration must be taken to factor what an amplifier output is capable of and the load you are introducing. Manufacturers clearly state what their amplifiers are capable of in output and in what situations or configurations. Car audio amplifiers are capable of driving a 4 ohm load. 4 ohms is what most car speakers and sub-woofers are rated at. Most car amplifiers are also capable of driving 2 ohm loads on a single channel.

Amplifier speaker connections

The most common error is when an amplifier is bridged, bridged operation utilizes two of the amplifiers channels and sums them together to provide more output. When an amplifier is bridged, its sees half of the load, or in the case of a 2 ohm woofer, 1 ohm. Most amplifiers are not capable of driving this low resistance as it would cause the amplifier to run extremely hot.

Single voice-coil and wiring options

Example: Paralleled connection

Subwoofer parallel connection

Paralleled configuration means the positive side of one voice-coil and the positive side of the other voice-coil to the positive side of the amplifier. The same connections would be made to the negative side, negative side of one voice-coil and the negative side of the other voice-coil to the negative side of the amplifier.

In this diagram we show you what is potentially a damaging load for most amplifiers. When paralleling dual 2 ohm voice-coils, this creates a load at the amplifier of only 1 ohm. 1 ohm loads for most amplifiers are catastrophic, please check with your amplifier manufacturer before connecting a sub-woofer to the output terminals

Example: Series output

Subwoofer series connection

Series configuration means that the sub-woofers are wire one after the other. The plus of woofer 1 to the minus of woofer 2, the remaining plus and minus are connected to the amplifier.

In this diagram we show you a load that is safe for most amplifiers. When connecting two 2 ohm voice coils in series you create a 4 ohm load. In a bridged operation this is safe for most amplifiers.

Multiple voice-coils and wiring options

In the examples above we were only talking about a single woofer and single voice coil. When we add multiple sub-woofers we can create different loads or resistance on the the amplifier. The sole reason for driving different loads is to optimize the amplifier to the amount of speakers.

Sub-woofers with dual voice coils have two connections and allow for different wiring options. This is especially useful in system design and allow for more flexibility. A dual 2 ohm woofer can be wired as a 4 ohm in series or 1 ohm in parallel. You can see this allows us a ton of flexibility when doing multi-speaker systems.

When we want massive bass the output of two woofers helps create the system we desire. When using multiple sub-woofers we must consider what the amplifier is capable of and the impedance implications that the multiple woofers present.

When speakers are in series, you add the speaker impedances together for the total impedance. One 4 ohm woofer wired in series to another 4 ohm woofer sums to a total impedance of 8 ohms. 

When speakers are wired in parallel, provided they are of equal impedance, you divide the impedance by the amount of woofers. One 4 ohm woofer wired in parallel to another 4 ohm woofer has a total impedance of 2 ohms. Another example is when four 4 ohm woofers are wired in parallel the total impedance is 1 ohm.

3 Dual Voice Coil Sub-woofer Setup Example – 2.6 ohm load

3 dual voice coil subwoofer connection diagram

Example 1: If we wanted three dual voice coil woofers in our system, and each woofer were dual 4 ohm coils we can wire this so that each woofer has its coils wired in series or 8 ohms each, and each woofer wired in parallel to the others so that the amplifier would see 2.6 ohms.

4 Dual Voice Coil Sub-woofer Setup Example – 1ohm load

4 dual voice coil subwoofer connection diagram - 1ohm load

Example 2: In this example we will take four dual 2 ohm woofers. We will wire each woofers coils in series making it a 4 ohm woofer, we will then connect them to the other woofers in parallel, the total impedance is 1 ohm for this system.

4 Dual Voice Coil Sub-woofer Setup Example – 4ohm load

4 dual voice coil subwoofer connection diagram - 4ohm load

Example 3: In this example we will take four dual 2 ohm woofers. We will wire each woofers coils in parallel so each woofer is 1 ohm. We will the wire each woofer in series to the other, the total impedance is 4 ohms.

This allows us to properly match the amplifier with the amount of woofers we want for the desired output. Consideration must be taken to ensure that the amplifier has the output capability to drive these multi-woofer systems. If each woofer is capable of 200 watts and we have three woofers we want to ensure that out amplifier has at least 600 watts of output. It is vitally important that we figure RMS ratings in these estimations as these are real world outputs and ratings. Multi-woofer systems that are underpowered will suffer from poor sound quality and possible damage as you exceed the output capabilities of the amplifier. Exceeding output capability causes the amplifier to clip and has the possibility to damage your woofers. The safer route is to have a slightly overpowered amplifier as it allows for more capability or headroom. This headroom prevents distortion when peaks of music occur and provide excellent sound quality as there is power on reserve for these impactful moments.

4 Dual Voice Coil Sub-woofer Setup Example – 4ohm load

Normal voice coil in good condition

In this photo we have the voice-coil as it should look when it is in new condition. Here you can see the tightly wound copper coil and the copper varnish is not discolored.

Burnt Voice-coil with broken former

Burnt voice coil

This photo clearly demonstrated a damaged voice-coil former and damaged coil. The coil varnish is severely discolored which demonstrates excessive heat caused by distortion. Excessive heat causes the voice coil to separate thereby destroying the woofer.

Burnt Voice-coil with broken former

Broken voice coil

This photo clearly demonstrates the severely discolored coil varnish. It’s easy to see the charred remains and the unwinding.

The bottom line is we want a sub-woofer and it’s amplifier to have very similar ratings. We want the amplifier output capability to match the woofer input capability at its impedance rating. By doing so we ensure that we have a well powered system and one that was designed with excellent efficiency.

Headrest monitor helpful hints

Headrest monitor installation tips

How do I know if my headrest monitors will match up with my vehicles interior?

When purchasing headrests monitors one of the biggest decisions you’ll have to make is deciding whether to purchase universal headrest monitors or vehicle specific headrest monitors. Universal headrest monitors typically come in three generic colors, black, grey and tan. They also come in a generic shape and only come in vinyl. Vehicle specific headrest monitors will match your vehicles current headrests exactly from shape, color, material and even stitching.

How do I know if I can use wireless headphones with my headrest monitors?

The ability to use wireless headphones with an aftermarket headrest monitor is a pretty standard feature known as built in dual channel infrared (IR).

What type of wireless headphones would work with my headrest monitors?

If your vehicle is equipped with aftermarket headrest monitors more likely than not it is equipped with dual channel infrared capabilities, a pretty universal form of transmitting sound, any of our dual channel infrared (IR) headphones would work. If the headrest monitors came factory with the vehicle, they could either be equipped with universal infrared or a more vehicle specific form of transmitting sound known as radio frequency.

How do I know for certain if my headrest monitors work of universal infrared (IR) or radio frequency?

One of the basic tests I recommend people can do to find out if they have monitors that work off infrared or radio frequency is the proximity test. Infrared technology is relatively limited by proximity, meaning the user has to be pretty close to the direct line of sight of the monitor in order to work, if not the sound sharply cuts off. Radio frequency is much less dependent on proximity and direct line of sight, with the ability to collect sound even outside the vehicle.

Can I watch the same movie on each headrest monitor if they both have their own DVD player?

Yes, many if not all of our headrest monitors come equipped with a standard RCA input which you can use to connect both monitors using a single RCA cable. These connections can be commonly found under the car seat so the wires aren’t exposed and remain relatively discrete.

How do I make sure my headrest monitors will be able to play the audio over the cars speakers?

The ability to play audio over the cars’ speakers is a relatively standard feature know as an FM transmitter. An FM transmitter allows you to wirelessly play audio over the cars’ speakers through an FM radio station.
