i found a sweet deal on craigslist for factory sub and amp. I am looking for a little bump nothing crazy. Are the cars hard wired as there should be a plug somewhere for the amp or would i need to run a power wire etc...?? also would i need a factory bose head unit as well?? Or would all this work with my stock stereo deck?? if not theres a factory bose deck locally for cheap as well. anyone done a mod like this or removed there factory stuff that could give me an idea of whats involved?? I found it cheap enough and its more then enough bump for me if its simple plug set up. I tried doing a little research but couldnt find anything on it. Anyone who can help please do!
