So i installed my system in my 2013 gs350. non ml system. I tapped the amps sub wires to the lc2i. Remote wire is ran out of lc2i to the amp. Im getting feedback when i turn off the car. So should i run the remote wire for the aftermarket amp to a cig lighter or is the a remote wire at the factory amp.

I also need help tuning the lc2i any detailed directions will help.

Where did you ground the L2Ci? It shouldn't share the same ground as the amp. Ideally, it would be grounded in the same location as the head unit. I'm not sure how that would affect feedback only when the car is turned off though. It looks like the L2CI has a GTO signal sensing turn on, you might try that instead of the remote wire. My JBL amplifiers have that feature and it works. I still prefer the remote wire because it turns on and off right away. I'm not sure if the wire you tapped is an appropriate remote wire though. It should just be +12v without any signal as long as the stereo is turned off and then it should be 0v when the stereo is off.
