I have a 2003 mcs. The amp went out and I went with an after market head unit. Here's the situation. ... I have the stereo hooked up to the factory harness with the aftermarket harness, but no amp. ..I know there is a way to hook all of the speakers up to work on it workout one. I just don't know the correct way. Does anybody know which wires go with which to make the radio play clean?
If it is....you basicly have to rewire it.... The HK amp uses line-level inputs.... AND to make it harder....the speakers on HK cars have a non-std impedance.... So they will damage most radio's/amps given time......
Chris has an HK system he's selling. It from an '06 so you might want to check and make sure it will work. http://www.motoringalliance.com/forums/1st-generation-parts-sale/21248-06-r53-part-out.html#axzz2yxSf9XDZ
