Hi all. I really want to upgrade my stock 6-disc changer with a Double DIN stereo w/Nav, rear camera, etc...I've found several different models that I think will work, however most seem to be designed for 4 speakers, but I believe my model MDX has 6 speakers (4 stock + 2 Bose) + subwoofer. Will I need some sort of special wiring harness/adapter, or can I simply wire the front Left and Righ speakers as pairs (i.e. 1 Bose speaker + 1 stock door speaker on each side in the front). Thanks for any help!
