Okay, so I'm having a custom enclosure molded to fit the trunk of my 96' 740il and using two Kicker Competition 12" subwoofers.

1) Where is the best place to find a IGN(+) source to run the remote turn-on for my amplifier ?

2) Does anyone know of an adapter that fits the factory amp and gives RCA outputs for running an external amp ?

3) Does anyone have wiring diagrams for the in-trunk portion of the audio system in a 96' 740il ? I have the DSP sound system option.

Thanks
