BMW M3 Forum (E90 E92) - View Single Post - Tapping into rear speaker/sub's from the trunk

09GT · 01-02-2013, 12:43 PM

I have a 2008 M3 sedan with premium audio and can't seem to find the exact answer I'm looking for in "Search".

I have a setup from my old car, its a OEM 10" Kicker powered sub from my old SRT8. It has a really easy wiring harness, that needs to be grounded, connected to the battery, then has self tapping connectors that need a signal from a positive and negative speaker.

Does anyone have a diagram of where I could tap into some speaker/ sub wires from the trunk?

Thanks.
