Well im only 16 and budget is kinda an issue. I'm getting a head unit installed because my old one was stolen and the wiring is bad. usually i would put it in myself.

a guy my dad knows is going to put my head unit in and my subs and amp for $50 and clean the wiring up some. it needs new wiring to the door speakers, and new door speakers. and some other little stuff...its got some tweeters in it that need wiring up.

but when i get some cash i'll throw a nice amp in there, i might be able to find one used for a decent price
