Hey i installed tha d3 gps today, the problem is that the front 2 door subs don't work, how would i go about to get them working.

the rear subs DO work? Most of the time to turn the subs on all you need to do is connect the remote turn on(blue/white) of the new deck to the amp turn of in the stock wiring(blue/white).

page 2 of my cardomain page shows integration of a deck into a 94 gt. It does not have to be as hard as I made it but I tweeked it with some passive x-overs and was suprised how good the stock system could sound.
