Hi All,

I got a 2010 530d with CIC unit + base speaker (no tweeter, front + rear + underseat subs).

I'm trying to find the best way to get 4channel signals back to an aftermarket AMP in the trunk. I already coded the unit to HiFi, so I guess it's flat enough to get started.

However... Anyone knows where to tap in into oem wires? I suspect all the 4 channel runs together till some point (maybe center armrest?).

Once it's sorted out, I will run new wires to speakers from AMP, so oem speaker cables won't be in use after that.

Thanks

Found below diagram. It helped to find the cables and all setup now.
