Do you still have the factory amp?
If so, it likely bit the dust. Bypass your factory amp and see if you get any sound... If you do, it is not going to hurt anything to leave it bypassed (I did).

If it works and you just want to leave it, you can buy a bypass harness that looks "prettier." However no one will ever see it in the trunk and I just left the jumper wires on mine. The radio sounds better without the amp anyway. Just unplug the power to it and bypass that sucker.

Yea its still in the back. It was crazy because It went out one day, and then came back on. Did that a few times and then finally went out, lol. But I'll try to bypass it and see if that works.

Yup. That's what most of them do when they are failing, and then they just completely conk out....

I just realized you have a 2004.... I'm going to post this for you as you have a different amp than in the link I previously posted. Disregard my first reply and here you go:

2002-2005 Don't follow the same amp wiring as the 2000-2001

You need to follow this pinout:
A9 -> C
A10 -> D
A11 -> E
A12 -> F

B9 -> K
B10 -> J
B11 -> H
B12 -> G

You can't connect the front tweeter at the amp unless you add a crossover

I found that the failure of mine was due to a splice in the power (Orange) wires running from the fuse to the rear. I had power at the fuse and HU but not at the amp...took my Power Probe and applied power to the amp and it fired up and the tunes flowed once again. There is a splice in the system someplace near the B-pillar that get wet and corrodes creating the broken connection. (I forget where I read this) I have a simple bypass wire running for right now, until I pull the pass seat to repair the SRS module, which is covered in corrosion, I will tackle that splice as well. Love that nasty sticky tape!

Hi... I know this is an old thread but I am trying to troubleshoot my Impala's radio to determine if it's the radio crapping out or the amp... The sound cuts in and out... I have a 2001 Impala LS... I want to temporarily bypass the factory amp... The instructions in your link are a little confusing... For example jumpering A1 to A9... A1 is subwoofer speaker return - RIGHT and A9 is speaker return - left rear... At least according to the pinout chart in the link... Is this correct?
