Kicker Subwoofers – Best in BASS

But a box is only as good as the subwoofers inside. CompR Subwoofers get their boast worthy power handling from their stacked magnet structure. Kicker’s signature double stitching bonds their improved Solokon, which adds rigidity and accurate response, to the ribbed Santrpoene surround, which provides flexibility to eliminate distortion.

These car subwoofers have a final impedance of 2ohm. The dual 10″ has a max power of 1,600 watts, the dual 12″ has a max power of 2,000 watts and the single 12″ has a max power of 1,000 watts.

To provide improved thermal management Kicker designed the structure of the CompR with their UniPlate back plate and Ultra ridged cast aluminum basket.

How to set amplifier gains – What is clipping? – Smoke!!

What is amplifier clipping?

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.

clipping audio signal
Here is what a clipping and non clipping audio signal look like on an oscilloscope

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.

Clipping is important to understand because it has a direct impact on how we set our gains

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.

distortion blows speakers
Distortion does nothing other than destroy car audio equipment

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.

testing audio signals
Perfectly formed sine wave uniform top and descending arc, the way an audio signal should look like

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.

pioneer avh-4200nex double din radio
Here we tested the AVH-4200NEX both the speaker outputs and the line level rca outputs

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.

Review on the Pioneer AVH-4200NEX Double DIN Radio

We’ll start with setting the EQ to powerful and take some measurements.

AVH-4200NEX Equalizer setting
Here we set the EQ to powerful before we begin out testing of the internal amplifier

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.


No clipping

Slight Clipping


30 Hz




60 Hz




100 Hz




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!

Here we set the gain without clipping the output signal.

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.

Audiovox AVXMTG10UHD

AVXMTG10U Flip Down MonitorFlip 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 – What are they and how to install DVD’s

What are Active Headrests?

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).

dvd headrest monitors
You can have DVD players in vehicles that are equipped with Active headrests

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

The completed installation of the Rosen AV7700 Active Headrest DVD System

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.

This customer wanted to have speakers attached to each headrest so that headphone would not be required. Here you can see our custom work

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.

Single Din vs Double Din – What’s the difference?

single din and double din size difference
What is the difference in radio size? We show you the size differences in single vs. double din.

What is DIN?

DIN stands for Duetch Industri Normen, this was a technical standardized opening that all of the vehicle manufacturers adopted. DIN is a colloquial term for an opening size of 180mm x 100mm. This is easily converted to inches by dividing by 25.4, the result is inches.

What is the difference is radio sizes?

What is double and single DIN?

It’s common to hear these question when you are replacing the radio in your vehicle. Luckily the vehicle manufacturers have made this easy. We explain all of the common radio sizes and nomenclature.

Single DIN

Single DIN is one unit of the standardized size, this means that the radio opening is 2″ in height and 7″ in width with varying depth.

Double DIN

Double DIN is two units of the standardized size, this means that the radio opening is 4″ in height and 7″ in width with varying depth. Many radio manufacturers build double DIN radios but you can also stack two single DIN chassis together to create a double DIN.

Din and half

DIN and a half is 1.5 units of the standardized size, this means that the radio opening is 3″ in height and 7″ in width with varying depth.

Half DIN

Half DIN is .5 units of the standardized size, this means that the radio opening is 1″ in height and 7″ in width with varying depth.

Smaller than DIN

Smaller than DIN usually adopts the height but is narrower in width than 7 inches. This measurement is commonly used with DVD players

Based on your make and model of your vehicle it can either support a double din unit, a single din unit or both.

Ultimate Holiday Gift – Pocket Jump Starter & Phone Charger

We have all been there at one point or another, when we forget to turn off the headlights in our vehicle and don’t return back for hours.

Sure jumper cables are nice but that requires someone nice enough to help or if your like most people about a 30 min wait until a friend or relative can come to the rescue.

You can also buy a conventional jump starter which is a lot more convenient but you may not have the room in your vehicle for it.

Then there is the PowerAll PBJS1200R that is about the size of a smartphone but not only has the power to jump start even the largest vehicles up to ten times in one charge but can also make sure you don’t miss a call or text as it can charge most cell-phones as well.

The 200R is so small that hiding away in your glove box or tucking it away under a seat is but a simple task and convenient enough so that when you do need it, it’s always within arms length.

An added bonus to this little giant is its ability to be used as a standard flashlight with up to 120 hours of use. Still its 12 amp High capacity Lithium Ion battery with 400 cranking amp discharge capability is what remains the most impressive feature and should be able to start virtually any car on the road.

As far as your phone is concerned, the 200R comes with all the adapters shown below, including the most popular phones such as Apple iPhone and Samsung phones.

The PBJS1200R is currently $99.99 and available here–>
