How is the system connected? Are you using aftermarket amp or factory amp, check speaker wire from amp yo subwoofer, and volume levels kn the amp if aftermarket.

It should be behind the glove compartment against the right side of the dash.

Search for a wiring diagram for factory amp and use that to connect aftermarket amp.

It sounds like you removed the remote wire from the factory amp to run your aftermarket amp. You need to reconnect it, and if necessary, split it to go to both.

I just built a factory amplifier/crossover bypass adapter for my 2002 Chevy Tahoe Z71 (non-Bose system) . This adapter will allow the full range of audio directly from your head unit to the door speakers. Without this adapter, the factory amplifier will cut out much of the bass / low frequency audio to the door speakers. This adapter will continue to provide an audio signal to the factory amplifier for the rear factory subwoofer and cargo area pillar speakers.


I have posted an article with complete set of step-by-step instructions and detailed photos of the build and installation process.

The article also includes direct links to the exact parts that I purchased on Amazon to build this bypass adapter.


This is what the end result looks like. It is a 100% non-destructive adapter than can be installed or removed from the Tahoe at any time. It just plugs in between the factory wiring harness and the factory amplifier.

Good Luck!

I can definitely solve your issue. I just need to know a few things.
1.) Was the factory amp used in the install of your aftermarket deck?
*if equipped the amp would be located underneath the passenger side seat*
2.) Did you use a cable harness to connect to the factory harness when you installed the aftermarket deck?

What you have been told is correct, these proprietary systems are great for the manufacturer, but when they start to have issues (and they will) they leave you 2 options: pay through the nose to stay original or replace the amps with new ones....the upside of this is aftermarket amps are soooo mugh better than stock that it is lauhgable.

I had the same problem and here's what fixed it. By default, I did not connect the blue/white striped remote wire to the harness. Apparently there is an amp somewhere in the vehicle I did not know about. After looking at the factory wiring and the aftermarket harness, I noticed that the remote wire was used and I connected it with the remote wire on the harness and everything came up and worked perfect.
