I like audiobahn myself. I got 2 12's for my 84 club wagon and i ended up with a rainbow crack in my window. I know they arent the loudest out there but I love them.
I say the same box and speakers for sale for 120.00 at a flea market. (no I am not kidding) It all depends on your budget on what we can tell you what to get. First of buy a new car without all the holes in it. I install custom systems and I just put in a OBCON GZ series enclosure with and eclipse head unit, well the list is to long to mention, but to sum it all up the stereo cost him over 3,000 and his car was worth 450.00 (not kidding).
