Ok, so i wired up an 01 6 disk unit into my '00 mach 460 system....partly. I have the 'tweeters' working(the high door speakers and high frequency rears). I need to know if anyone knows where to find/how to find the low signal for the doors and for the rear. The 01 units have an internal amp for the highs so i skipped the dash amp but now i need help finding the rear low signal and door signal. Any Help!??!?!
