I just put 2 12" Fosgate subs and 6 1/2 composites in mine and ran them all off the stock deck. I didn't want to change the dash either, especially wasting money on the faceplate (bad reviews anyway). I used a line reducer (high to low input) and my system thumps!! Fyi, there is no acc wire in the stock harness, only a constant hot. You have to tap into the fuse box to get accesory power. Hope this helps.
