Clipping at its root is distortion. It occurs when an amplifier is overdriven and attempts to deliver an output voltage or current beyond its capability. Like the guy at the gym trying to squat 10 plates. It is important in car audio to avoid because we want to have all of our components in the signal path optimized to prevent the onset of distortion. Clipping has disastrous consequences for our speakers.
Why is this important?
Amplifier clipping comes into play into two places in our audio system, our speaker level amplifier and our pre-amp level amplifier. This is hugely important when we set the gains of our amplifier. We want to match the maximum output of the pre-amp level to the maximum speaker output of the amplifier. This ensures the best audio quality from both the radio and the amplifier.
What does clipping look like?
Audio signal are a series of waves, these waves have perfectly formed tops and bottoms. Clipping causes the wave to no longer have a perfectly formed top or bottom. To show you what this looks like we will use a 30 Hertz test tone recorded at 0db and connect an oscilloscope to the speaker output of our radio. To see clipping we need to increase the volume to exceed the output capabilities of the amplifier by raising the volume.
Here we have a nice clean top with a descending arc, and now you will the top of the wave get cut and that is amplifier clipping or better known as distortion. The byproduct of distortion is heat and that has lovely effects on our speaker voicecoils.
Are some radios better than others?
We’ll take it a step further, depending on the quality of the radio or amplifier you may have clipping at different frequencies, a 1 kHz test tone may play fine, but a 30 Hz test tone will clip at the same volume level. Add in the fact that some radios have EQ’s and that creates additional issues.
To demonstrate this we’ll show a couple of examples utilizing the AVH-4200NEX double DIN radio. Make sure to check out our review here.
We’ll start with setting the EQ to powerful and take some measurements.
We begin our test with the internal pre-amplifier and test using a 30 Hz, 60 Hz, and a 100 Hz test tone to see if our radio can maintain the same volume setting on all three test tones. We have gone ahead and hooked up our oscilloscope to the front RCA output leads and begin playing our 30 Hz test tone.
Based on that test you can see that the internal pre-amplifier is pretty clean until the last 10% of the volume range. Mind you we took this test with only a single RCA connected with a very short lead.
Now we’ll show you the how changing the EQ curve has a direct effect on pre-amplifier clipping. We set the EQ to flat and begin all of our measurements.
What does clipping sound like?
Here in our examples you can actually hear when the amplifier clips, it make an almost rattling or slapping sound.
How do I use this to set gain?
To set gain we set the radio to volume 38, this is the maximum clean output of the radio. Volume 38 will also be the volume level that we would never exceed when playing music. Next we connect the RCA’s to the amplifier and turn the amp gain all the way down. We connect the oscilloscope to the speaker outputs of the amp and increase the gain until our wave begins to clip. Our gain is perfectly set!
In this video we used an inexpensive $89 oscilloscope the DSO Nano, if you are into car audio and electronics this is a must have. Click in the description below for more info and where to get one.

Moving towards a slightly more competitive category, flip down monitors just under $250 can come in all shapes and sizes but most people a 9 inch flip down should be plenty.
The AVXMTG9U is definitely the cream of the crop in several different areas in this category. What really sets this monitor apart from the rest is build quality. An Audiovox unit even feels sturdier in your hands than other flip downs.
As far as reliability goes this unit is an absolute champion. It is widely considered as one of our products least likely to be returned for defective reasons and built to last for years of use.
he 9U has every feature you need in a flip down such as a SD card reader and USB port, as well as built in dome lights.
Flip down monitors worth noting in this price range tend to stay between the 10-12 inch range and can come with extras such as free headphones included. Still the best monitor for the money is the Audiovox AVXMTG10U 10 inch flip down monitor.
Although this particular monitor does not come with any extras it does not need them to provide the best value in this class. A reliable DVD loader that plays smoothly every time as well as a sturdy build more than make up for lack of freebies.
A great thing about the 10U is that it comes in with all three colors in the box. Sure the black will already be installed but one can easily replace the color to grey or even beige by replacing two quick trim pieces.
With infrared for headphone use, fm modulator to listen over the cars speakers and a crisp quality picture to round out the unit, you can’t really go wrong with this monitor as it has no real weakness except maybe for the fact that it does not have external speakers.
Active headrests are normally found on newer vehicles as a part of the cars safety equipment. These headrests are referred to as active because in an event of an accident the headrests actively move forward to cradle the head and prevent whiplash. A quick look into your vehicles interior can help identify whether your car is equipped with an active headrest restrain system. Vehicles with active headrests commonly have what looks like a rectangular shaped plastic enclosure on the back of an otherwise cloth or leather headrest (See picture below).
Can I still have DVD in the headrest with active headrests?
Removing the active headrests from a vehicle would not only cause the airbag light on the dash to turn on but may also void the vehicles warranty. Aftermarket headrest DVD manufacturers usually get around this problem by designing DVD headrests specifically made for vehicles with active headrests that simply attach to your existing posts, without the need of removing the headrest. Universal active DVD headrest monitors will only come with a plastic enclosure in a black, gray, or tan color. However companies such as Vizualogic and Rosen specialize in designing headrest buns that are enclosed with the exact material, color and stitching as the one found in your current interior.
How to install active DVD Headrests
We recently installed some active headrest monitors on a BMW X5 made by Rosen, one of the companies dedicated to matching your cars interior and delivering high end monitors.
This particular installation called for a bit of a custom job as the customer was looking for built in speakers when these Rosen units don’t carry any. What we did was attach a computer speaker to these monitors and attach a seperate volume control.
Here is a quick view of the X5′ s active headrest monitors before installing Rosen’s active headrest monitors.
The back of the seat must be removed in order to run and hide all of the wiring needed to complete the installation.
Removing the back of the seat and running the wires that will ultimately run to a control box that will house all of the systems connections is often the hardest part of installing these headrest monitors Rosen AV7500 Installation Manual.
Once all of the wires have been ran to the bottom of the seat where the control box is located you are ready to close the back of the seat.
All the connections on a Rosen headrest system ultimately must connect to a control box which the installer will place on the bottom of the driver or passengers seat. This control box controls the power source and houses the headrest monitors RCA connections.
On vehicles with active headrests you cannot remove the headrest without voiding the vehicles warranty or causing the check airbag light to turn on so active headrest monitor simply attach to the back of the headrest as seen above.
All connections are ran through the back of the seat so no wires show when the installation is complete.

If you’re installing a subwoofer and amplifier in a factory-amplified audio system, you may have some questions. This is a common modification for vehicles, but before you begin switching wires around and dismantling the existing parts of your automobile, take a look at our how-to guide.
1. Identify Equipment & Wire Placement. You need to run the positive lead to the positive terminal of the battery. Only the driver’s and passenger sides of the footwell have access to the firewall. The driver’s side is optimal, as it generally allows to an empty grommet or the ability to piggyback from an existing cable bundle. If this side’s space is, you’ll have difficulty feeding the power wire to the battery. Use the passenger side footwell to gain access in these cases.
2. Locate a large grommet with ample space.
3. Locate a cargo bin with plenty of room for your device, which will give you easy access during installation, as well as for any future needs.
4. Disconnect the negative lead of the battery, and remove all of the paneling on the side of the vehicle that will house your device.
5. Organize all parts by location, and use bags to store the hardware so you can easily reassemble your vehicle when you’re finished.
6. Disable the subwoofer. Disconnect all factory wiring behind the car’s paneling.
7. Test for factory subwoofer speaker leads. Use the subwoofer speaker outputs from the factory amplifier. Determine which wire to use by visually confirming the wire color at the factory subwoofer and amplifier.
8. Verify wire colors using volt meter and cheater lead. Check out our video Testing for Continuity for further assistance.
9. Test for Phase prior to disconnecting the battery or use a phase detector after removing the battery.
10. Test Speaker Level Inputs.
Connect your leads to the signal wires you tested earlier.
Pull the speaker leads and remote turn-on through the factory hole in the carpeting to the factory amplifier.
Run the power lead through the hole drilled in the grommet under the dash.
***Tip*** Undersize the hole you drill in the grommet to ensure a tight seal between the wires and rubber grommet to prevent water from coming in.
11. Shield the power lead and ensure an original look:
Use split loom tubing.
Tie off all wiring to the factory wiring underneath the lip of the firewall to the battery.
The power lead must be fused in a proper location, which is ideally within six inches of the battery.
12. Mount your fuse to the factory battery mount. See our video How to Wire a Fuse.
13. Ground your connections. The ground lead is connected to the factory ground point near amplifier. To provide an ideal ground, remove paint with sandpaper.
14. Prep the storage compartment:
Determine the mounting location.
Drill holes proper holes for the cabling.
Install plastic bushings to clean hole and protect wiring.
With all cables run, reassemble the vehicle, and prepare final connections.
15. Prevent sparking:
Use a test light connected to positive side of battery and slowly charge amplifier’s power supply.
Before connecting battery, make the final subwoofer connections.
Prepare the subwoofer speaker wires from the amp to the subwoofer, now connecting negative lead from the battery and testing remote turn-on.
16. Use crimp connectors to make connections. Once connected, turn on the system and adjust gain and crossover settings. Use factory audio settings to fine-tune your new audio system.
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.
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.
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.
This in depth video is meant to be a reference manual on how to do the entire installation. Make sure to check out our other videos on back up camera installation and the concepts behind the entire process.

Let’s face it, installing an aftermarket car stereo can appear to be a daunting task. With some basic skills nearly anyone can successfully install and aftermarket radio in their vehicle. Learning these basics of car stereo installation without a teacher can take years. We show you the tips of the trade and the basics of an aftermarket car stereo installation.
The Metra wiring harness is specifically designed to plug in to your vehicle’s factory wire harness without having to cut the factory wiring. These harnesses have color coded wires to make connection much easier for the novice. All aftermarket radios have a standard wiring color that matches up with the Metra Wire harness. Be sure to check out our video on the difference in wiring harnesses here.
Step #2 Car Stereo Dash Kit
In the second step, we take you through the process of mounting the aftermarket radio to the Metra Dash kit and preparing to install the radio in the vehicle. This part of the stereo installation is often the easiest part as it is aa matter of mounting.
If you have any additional questions please feel free to ask us below.
Maybe its the Navigation, maybe its the ability to play DVD’s in your vehicle while on the road or it might just be the ability to play songs directly from your smartphone wirelessly, whatever the reason might be for you to want to upgrade your stock radio, there are only a few steps that you’ll need to take to make sure your installation goes as smoothly as possible.
Step-by-Step installation instructions
We installed a feature-packed Pioneer AVH-X3500BHS(Now Replaced With the AVH-X3600BHS) on a 09 Tundra. Like most aftermarket radios the X3500 is compatible with the stock steering wheel controls but we had to add an interface to make it happen. For the most part this was a fairly standard head unit installation but we also needed to add a special harness to bypass the JBL components on some Toyota vehicles.
We chose the X3500 (starting at $349.99) for Pioneers reputation for quality and reliability as well as what seems like its endless entertainment options. The X3500 has the ability to play Sirius XM satellite radio, HD radio, play DVD’s/MP3’s and has industry leading Parrot Bluetooth technology to stream music from your phone wirelessly including Pandora playlists and answer phone calls on the go.
Apart from having to add a couple of adapters, it did not take much to transform this technology outdated stock radio, which even has a cassette player(not that there is anything wrong with that) with top of the line technology.
We walk you through the process below to help you get a better feel on how easy it can be to upgrade.
Step 1: Removing the factory head unit can sometimes be a bit of a pain but the first step is to remove the plastic housing surrounding the unit. In this 09 Tundra the plastic housing includes pretty much the entire dash in a circular form.
Once the housing is out, the head unit itself should be held in place by a couple of screws, simply remove those screws and un-clip the wiring harness as seen in white (above) and you have the blank canvas for your new navigation.
Step 2: While upgrading to a new navigation receiver our customer wanted to make sure he did not lose his ability to use the factory steering wheel navigation controls. We were able to keep the controls by using the Metra ASWC-1, a steering wheel control interface for select aftermarket radios that can be bought for around $50.00.
This 09 Tundra also needed an adapter that would make it compatible the stock JBL equipment already in the vehicle. With Metra TYT001 we are able to use the stock amplifier and stock speakers with the aftermarket navigation receiver for about $75.00. This double-din unit did not need a dash kit as it fits practically snug without additional housing.
Step 3: Once all of the wiring interfaces and adapters are in place, installing the new navigation receiver is about the same process as removing the stock radio to begin with. In this case, we attached the JBL adapter to the vehicles stock harness and connected the steering wheel adapter.
Once those two connections have been made, we hold the unit in place using the same screw holes we used to remove the stock unit. The picture on the left should show exactly how it should look once mounted. Once that is mounted all that is left is to place back the plastic housing that hides all of the electrical connections of the dash and the installation is complete.
Metra provides two types of harnesses for different installations. Occasionally you may need to replace the factory harness and in other situations you want to replace the factory radio, we show you the differences between Metra wiring harnesses.
Replacement vehicle Harness – 71-
Metra produces two types of wiring harnesses, one is designed to replace the factory wire harness in the vehicle if it becomes damaged. These wiring harnesses have a part prefix of 71-****.
Aftermarket Radio Installation harness – 70-
The more commonly used Metra wiring harness are those that are designed so that you can connect an aftermarket car stereo to the factory wiring without cutting. These harnesses have a part prefix of 70-****.
