    OEM replacement for my 2014 Buick Enclave with Bose speakers. Works perfectly.

    No sound, with power. Replaced the amp and fixed the problem. I would not try to replace with an after market amp. It’s hard enough to get the OEM amp in the space provided.

    I have a 2014 Buick Enclave. Like others, my sound completely went out. My husband is very much mechanical and a great handyman. But this was a monster to get out. Be prepared for that. Most places wanted to diagnose it first, even replace the speakers. (I have Bose) But I decided to go directly the the amplifier and replace it based on research on the internet.

    It’s working great. We had a car stereo guy put in for us. It was much cheaper than Buick was going to charge us for it.

    This product was the perfect replacement amp for my 2015 Buick Enclave. Price was awesome as the dealership wanted double the price. My son is an auto technian for Best Buy and put it in and said it went in great and works great!

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.
