How in the world do I connect the factory bose sub to the after market head unit? Is there some magic bose harness to rca plug out there?
@tonyamazing if you don't mind me asking where is this so called sub? I have the bose system in my 3 MPS but I don't really notice bass that I would expect from any kind of subwoofer even with bass set to max. The bass I get could be produced via a good set of 6.5" 2 way drivers that were sufficiently amplified. Is it a really small 6" sub hidden somewhere? Im starting to think mazda put a 6" BLT sub from subway in mine.
