i have a similar issue here, except my unit just fried and dont realy wanna buy another. So were just cut out the box and hard wired it up. the head unit turns on and fully works but there is no sound. does the cobalt have a bose type system?

off ebay... just hook your front speakers up to an amp and you dont need it

I got a Pac unit or something like that and it was 60 from crutchfield. Works great.

was this to my question? you mean hooking the front speakers up to a 4 channel amp and leave the rears on the harness?

07cobalt4life

well if you have a 4 channel might as well hook it up to the amp as well

do you have the pioneer system? pull out the interior fuse panel and look for a fuse labeled "amp"

i do, but the stock stereo works just fine

so if the radio works. and there is a factory amp but you dont have sound. then theres a good chance the factory amp isnt working or turning on. It probably blew a fuse. either way swapping the working radio for a working radio probably wont fix the problem

no no no, lol... the aftermarket isnt working because the box for the onstar crap and whatever else is broken. i tore apart the box and the circuit board is fried. so i put the stock stereo back in and everything works fine! except this: https://www.cobaltss.net/forums/electronics-audio-video-49/stock-sub-onstar-problem-173556/
