2009 MDX Aftermarket Reciever Install Using Factory Bose Amps?
 

Hi -
Looking for some help with my install. I tried to install a Sony reciever/head unit in my 2009 MDX. I ordered it from Crutchfield and it came with a Metra 70-1722 adapter. I made all the connections (power, speakers...) but when I installed it I discovered that the speaker wires do not go to the connector for the Metra 70-1722 adapter. The Bose head unit connects to two amplifiers, one for the front/back speakers and one for the sub. The Sony head unit has preamp outputs for the four speakers and the sub (5 total). My question is- Can I splice into the factory Bose amplifiers? If so, does anyone which wires are which?

Thanks,
Andre
