Ready to toss the MP680 in its final resting place, the trash bin, and am looking for a wiring diagram for the stereo. I want to keep the DSP unit but cannot seem to find a wiring diagram anywhere. I am pretty good with a soldering iron and cannot wait to get some punch into the system. Have replaced all factory speakers and still not satisfied. Head unit is the CDR-220 and amp is the MP680...have dash, door and rear speakers.
Much thanks!
Don
