Like the title says my brother just went out and purchased an 07 SS/SC it didn't have a raido when he picked it up. we went down to our local shop and had them order one up. Install is as straight forward as it gets with these cars, brought it down to the dealer still no sound but can cycle through everything else any help/advice on what the issue is?

 

check the inside fusebox for a fuse labled amplifier. If its blown replace it if not then look under the dash by there steering colum for a silver VHS tape sized amp. if its gone or wires look all jacked then see about returning that stereo and going all aftermarket

 

Fuses have already been checked ill have to look for the amp and wires going to it then
