E46 M3 Non Hk Sub Install

[rbk1016]

I was wondering if anyone on the forum had experience with installing an aftermarket amplifier to power a sub in an e46 m3 vert without HK. Any help or recommendations are appreciated. I am specifically looking for the particular wires to tap into for a hi-lo converter and also for accessory (turn-on). TIA

Tap into the factory amplifier wires. The amp is located on the driver's side rear panel (next to the rear seat) in convertibles. Turn-on wire is white. I normally tap into the rear speaker wires coming from the radio, that way you can decrease bass by fading towards the front with the radio:
LR Speaker (+) YELLOW/BLACK
LR Speaker (-) BLACK/ORANGE
RR Speaker (+) BLUE/BLACK
RR Speaker (-) BROWN/ORANGE
