Must be the power antenna wire.
Admins, can we sticky this thread? This is essential for anyone looking to add a trunk subwoofer with Technic's harness (or any method) in the '11+ F25 X3.

It's still a digital signal. If you draw too much current (too much Volume) your radio will go dead or dims out.
Ebay has a Solid state Relay that you can use to control the amps power. Search SSR DC Control. 3-24VDC will trigger The SSR. Some SSRs control AC. I found only one that controls DC.
I don't feel comfortable with regular relays (heat).
look here http://www.ebay.com/itm/121030518863...=p5197.c0.m619
this one handle 40Amps I have seen them that handle 60Amps.
Using the remote signal will work for about 5-10min until the system goes to sleep.

Im not sure what your getting at. I am Using the antenna wire for a remote turn on signal and it works marvelously. I have an alpine pdx-m12 amp and its running flawlessly. My radio never dims or shuts off.
