2001 Monte LS - Getting no audio out of all four speakers. Aftermarket head unit works fine. Swapped it out with the OEM head unit and still nothing. Could I have possibly fried the stock amp that powers the speakers? Open to any and all opinions

 

Either the amp is blow, or you just have a loose wire somewhere.

 

First thing i would do is recheck all the wires for the radio and amp. If everything looks good there then your down to one thing and thats the amp.

 

Get a power reader. I think you can get one at autozone, it reads the voltage coming off wires. Then you can check to the amp, and out of the amp.

 

I would try to wire around the amp for right now just to test if it is the amp then you only have one option. Assuming you did a clean install of the deck,but if you didnt its possible that if u didnt tape off any unused wires that they touched that was always my problem haha. Also I didnt install my stereo in my car, but when lookin back there I saw all kinds of different modules like the steering wheel controls and like 2 other.
