OWC Exclusive
For any BOSE equipped 2008-10 M35 / M45 Sedan. 
Built with economy and good quality in mind, the RED LINE offers nice options to easily upgrade your audio system. Each interface simply plugs into the factory amp harness in the trunk, letting you Plug-N-Play Amplifier and DSP (Signal Processor) Upgrades! That way you can add subwoofers, push more power to the car speakers, and increase the clarity & adjustability of your sound system overall. It's mind-blowing how simple it is to upgrade! There is ZERO need to cut & hack (ruin) your car's factory wiring, spend days tracing & checking so many wires for signals, or purchase & run a whole bunch of speaker wiring all over the car (unless you choose). The Red Line is Professionally Built with Quality Materials, Labeled for Easy Connections, and Provides Clean Signals & Speaker Connections from the Factory Harness.
 
Note: You'll need to provide the main power & ground wire for your install.
