You need to make sure you have the wiring for the mach system as well and that it did not get hacked out, check behind the deck there should be 3 plugs back there plus an antenna. one plug is rectangular, and two are square and have metal on them, also the lower opening where the factory cd player goes will have two plugs as well, then you need the harness in each door for the 5x7 and the harness up in the mirror pods for the tweets, in the trunk of the coupes a big amp rack mounts that has 2 5x7's in it and the two tweets as well, plus the two amps mount here, most of the wiring is self contained in the amp/speaker rack for the rear, there will be two plugs for each amp in the rear one is square and black in color the other is rectangular and grey in color each amp has one of each, there will be 3 total amps 2 in the back on the rack, and one underneath the cd player, the rear 2 control all 4 5x7's and the front one controls all 4 tweets, good luck if you need some more help on putting it together let me know, i have worked with that system many a time Dan
