i think i am just going to repalce the whole audio system. i actually found wires throught the car for a sub and what not... they are preran, so i will try to see what they can hook up to.
i do not have an owners manual but if you wouldnt mind letting me know some more info or sending a copy of some pages to me i would greatly appreciae it.
as you said my first priority is the ABS, the door, and silencing the airfilter.
