An ACDelco GM Original Equipment Audio Amplifier is part of the audio system, and is a GM-recommended replacement for your vehicle’s original component. The purpose of the amplifier is to increase the power of a voltage or current signal. The output signal of an audio amplifier may consist of the same frequencies as the input signal or it may consist of only a portion of the frequencies, as in the case of a subwoofer or midrange speaker. The audio amplifier amplifies the signal and sends it to the appropriate speakers. Each of the audio output channel circuits (+ and ?) at the audio amplifier have a DC bias voltage that is approximately one half of the battery voltage. The audio being played on the system is produced by a varying AC voltage that is centered around the DC bias voltage on the same circuit. The AC voltage is what causes the speaker cone to move and produce sound. Both the DC bias voltage and the AC voltage signals are needed for the audio system to properly produce sound. These original equipment audio amplifiers have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

    Needed to replace when I lost all sound in 2015 TraverseI ordered this to replace the amplifier in my 2015 Chevrolet Traverse LTZ that has eyebrow Bose stereo system. The amp stopped working after a couple of loud clicks then there was no sound from the radio, turn signals or even door chimes. I did research and found out that the amp was the likely culprit. I also looked into the removal and install and it looked a little above my DIY skill set. FYI the amp is tucked way up in the dash beside the steering column and very difficult to get to. I don’t have the flexibility that I used to so I took it to my local mechanic and he replaced it for me. It was $300 labor but money we’ll spent. The install is not technically difficult so if your patient, flexible and handy you can probably do it yourself. Installing the new amp has fixed all the sound and we are back to full functionality.

    Works very well. Installation is difficult but durable if one is patient and goes slowly.Like: It works. Dislike: GMC didn’t make it easy to take out the old one and install the new one.

    Fit my 2015 Chevy TraverseI’m happy w this purchase. The amp going bad seems to be a big issue w these cars and this was an easy purchase and installation for an experienced person.

    This fit my 2015 GMC Acadia Denali.This fit my 2015 GMC Acadia Denali. Was the exact part number I took out. Solved my issue of no sounds, radio, door open, backing up to close to objects sounds. Worked great. It is a tedious job to get it out and put back in.

    Fits 2012 GMC AcadiaThe ad site said this amplifier did not fit in a 2012 Acadia, but it most certainly does. We pulled my amp out first and they have the exact same part number. Once installed, it worked great and fixed my problem.I must warn you that this is not an easy part to change. It is way down under the dash on the driver’s side. It puts the person changing it in a very uncomfortable and awkward position.My son watched a you tube video first, which said it would take about 45 minutes to get the old one out, with the right tools. The screws are very hard to get at and remove.He made sure he had the right tools first, and it still took him about 1 1/2 hours to get the old one out. Installing the new amp did not take as long since he had the old one out already.

    Harder to install than expectedMy son actually installed it. He said it was harder than expected but if it happens again I’m sure he’ll be able to do it faster.

    Amp fits and works great!! Exactly like factory equipment!Amp fits and works great!! Exactly like factory equipment! I only gave one star for remove and install but, this has nothing to do with the amp or the quality. It is a beast to remove the old one and reinstall the new one. That is because GM shoehorned that amp into a very tight spot under the dash. There are only three screws holding it in but you can only see one of them. It took several hours to replace. Should have been a 30-minute job. The amp solved my problem of no radio sound. Also, I didn’t realize the door chime and turn signal sounds are played through the stereo system.
