i'm trying to use my stock 6disk and just put a line out for the subs. i first connected it to the back of the radio and that did not work then i went to mustang world and they showed how to do it on a coupe and the wiring is different in the back for this data cable thing. so i'm not sure how to make it work.

 

I can't remember where the subs are on the mach. Find the enclosure and on the back of it you will see the signal/data wires.

 

i don't see a stock sub anywhere.... and i ripped the whole interior out

 

could be hidden behind the panels around the back seat.

 

i still can't find anything.. theres not a definite sound of a sub anywer back there. theres 2 looks liek 6 1/2;s or so that give alot of bass but tthat it i looked behind the rear panels there nothing.. hmm no data cable conector that i can find either

 

the factory subs are 5 x 7s I thought but they may be 6.5s. You need to thing factory sub not a real aftermarket sub.
