Check out www.peripheral-aamp.com (I think thats the address). They sell an adaptor box to hook up a kenwood changer they also have (I believe) a 10 wire adaptor for the harness you may already have in the trunk. What's nice is the adaptor box also has RCA inputs for an aux. device (DVD, MP3 player etc.) To play the empeg one simply grounds the adaptor box (simple to mount a switch somewhere) which switches on the aux. device and plays it thru the cd changer channels of the stereo. The ONLY catch is that you REQUIRE a cd changer to "trick" the headunit into accepting the aux. signal. As far as locating a mounting place - I would like to know if you come up with anything as my friend wants an MKII in his 2000 Monte Carlo which has the same radio as yours.

Good Luck
