I did something similar. Ended up using a JL 700/5 and JL 200/2 and the technic harness and all problems are solved. JL 200/2 powered the rears and 700/5 powered the front, under seat, and trunk sub (JL 10w6v2). This is assuming that your car comes with HiFi though. I got all my stuff through MusicarNW. PM (VP Electricity) to find out more and also check out their website. You can't go wrong with his solution!
