Quick question
 

I've got an old amp and subs from another vehicle. Can you hook them to the stock head unit in an 02 Blazer? I've got everything but the wires so it shouldn't be hard I just want to know if I can before I go ripping my dash out.

you need line out converters to use your stock radio. you can pic them up at best buy or any car audio place for like $10 per converter

Sweet, thanks man. Would radio shack or walmart have them? I know I know, walmart sucks but I'm not all that concerned about the quality of it. There's cheap walmart subs and amp so it's not all that important.

basically any electronics store should have them so I would assume they would you could always check out their website to double check before you make a run out there.

Walmart will have them but i just don't trust them. it isn't hard to hook up the converter, i just prefer an aftermarket radio because of the control they give you over your music

they are kind of bulky and hard to stuff them behind the radio. sound quality isn't as good as an aftermarket radio either
