adding aftermarket sub to stock soundsystem
 

I have a 2002 GT, without the Mach 1000 soundsystem. It has what Ford calls the "Premium" system, with a DIN and a half sized CD/Tape head unit, and front and rear speakers.

I have wired a sub/amp/box into a factory GM system before, and I know that I'll need a line level converter to do it in the Mustang...can anybody out there tell me if I'm going about this the right way? I know that with the converter, I'll have to tap into two speaker signals (probably rear speakers) but does this have to be done at the harness, or could I do the tap near the speaker connections? I have gotten alot of shadetree mechanic advice, and I figured you guys here would be the ones to know the answer.

Please describe in detail, if you don't mind. Thanks in advance!

1) Yes it CAN be done with a line converter, you should be able to tap into the lines near the speakers.

2) I would highly suggest upgrading the rest of your system first. I nice aftermarket HU would be great and greatly increase the sound quality of your sterio system. Replacing the door speakers with aftermarket units would also add a great deal of sound quality. At a minimum I would suggest replacing the stock head unit with a aftermarket CD player before adding subs.

http://www.mustangworld.com/ourpics/fcar/despeeds1.htm should be the same for the mach 1000. i am actually in the process today of doing exactly this. with the same box laid in the back seat and everything. my problem is that my line out converter isnt working right. i hook it up like it says and i get intermittent results. at first it works beautiful then fades out and stays off and all sorts of weird stuff. im gonna play with it more tomorrow and get it to work. i was crossing some wires just tonight after i got home and it seemed like somehow crossing the positive and negative wires gets it to work? :confused: :confused: i have no idea, but tomorrow i should have an answer. head to that link as it is fairly informal.
