Does your head unit come on? I know that i always tell people to check speaker leads for ouput voltage and most of you guys dont like to go through the trouble so... i hate to break it to you but thats what i suggest again. hahahaha! No but seriously, I would snip a set of speaker wires from the radio right before they connect into your wiring harness, turn the volume about halfway up and then check it for any ac voltage. If you arent getting any readings, then its the headunit. If you are and you are sure you wired it all correctly, its the harness. I gotta be honest, I did an install in an impala once with the same type of harness and it did something very weird. It had an internal short and would slowly drain the cars battery over night. It would only happen over night because that was the longest part of the day that it sat without being started to recharge the battery. painfull

yea it does come on and everything its just wont give nay audio out...

it seems like its not able to turn on the factory amp..

other than that everything else work fine...
and the HU is brand new i dreally really doubt theres a anything wrong with

any input on PAC C2R-GM32R?
