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.

How to install an Amplifier and Subwoofer in a car

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.

We take you through the steps of wiring a Clarion NX404 Double DIN navigation system. First we walk you through the steps of preparing the Metra wire harness and the connections to the Clarion Double DIN radio. Preparing the wire harness by stripping the appropriate wires and using crimp connectors to make those connections to the aftermarket radio’s harness.

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.

Complete in dash radio installation

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

Old factory radio

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.

Old radio completely removed

Old radio

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.

Our wire harnesses

Completed wire harnesses

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.

New radio ready to push into the dash

New radio installed in the dash

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 Wiring Harnesses Explained – 70- vs. 71- Video

Why are there two Metra wiring harnesses?

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-****.
