Everything it needed to be plus great value

Exactly what I needed to by-pass the amp on my 01 Impala. The price was fair and Sonic was very quick and reliable in getting the part to me in a very timely manner. I couldn't be happier with the service they extended me.

"Fixed" my stereo

February 21, 2011

My 01 Monte Carlo had its factory amp die out on me. This adapter allowed me to open my trunk, unplug the harness leading to the amp, and plug this in its place. Works great and I haven't noticed a difference running off my head unit. It seriously took longer to open the package than to install.

Cheaper than an amp

April 18, 2014

I had no sound from the radio, diagnosed it as a bad amp. A used amp still cost almost $200. This amp bypass kit allows you to keep all factory functions for a fraction of replacing the factory amp. It is a simple plug and play kit.

fix that radio that displays like its working but without sound

March 4, 2016

great price , great product , sonic did great as always " I am a frequent buyer " I should get frequent buyer bucks ! this is what you need to get your sound back , reverses fader but that isn't a problem , just readjust ! actually the stereo is louder & clearer than with factory amp ! finally a cheap fix for a common impala problem , can sonic come up with a pig tail for when installing an aftermarket radio we can just have a wire hanging down behind center console so we can grab it to hook factory radio up to reset tire and oil lights as well as control our security without having to get 17' retention wire to relocate radio to trunk ? That would be great !

Best Answer: Hello,

Unfortunately, no. Although on the right track, the first part cannot be used with the second, and the second (as specified in the description) need Another part to work right. You likely seek a GMOS piece, but you did not provide enough information to know that for sure. Use the link below to help and/or CALL our sales team.
