Your cart is empty.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.

Installation takes about 10 minutes. Product works and functions as it should for a GM product.

Our 2010 Cadillac SRX lost all audio. Replaced with this part and the audio now works. Was a perfect fit and easy to install.

Was searching for this replacement and didn't initially buy, but then had a little I could spend on it, the description was wrong but the connections and housing were correct, I just connected it with no issue of connecting, but with no luck there is no audio coming from the system, give it that the description was for a GM catalytic converter gasket but looked the part I purchased it to replace the one in my 2010 Mazda 3, I'm not giving up on it just yet because the description says it needs to be programmed, I'm just not sure where I can take it since it's labeled as a gm part but I have a Mazda, so if anyone could direct in a good direction that would be great, hopefully this thing works and if it does I'll be back to correct my review

Cerciorarse con la mejor exactitud posible en las entradas de los brackets. Lo habÃa comprado originalmente para un Mito Veloce 2017 y por una "patita" de uno de los brackets no tuvo compatibilidad.

Yes, this product does work for the mazda 3 platform with bose speakers (i own a 2010 speed3 and it works perfectly). The only downside is that you would have to drill an extra hole for it to fit on the bracket. I searched scrapyards, online and wreckers in my area and could not find the mazda 3 amplifier anywhere. I looked at the connections and this one matched, i saw another review that it would fit on here but there was no confirmation by anyone so i took the risk and it paid off. This amp does work.
