installed my amp today! yes finally seems like the x5 is desgined for aftermarket audio. thanks to alpac's article i done it in about an hour. i found the remote turn on lead to be pin 10 on the grey holder. (if u have the 42 pin) so that should help u guys from using a voltmeter and checking every single one..
one thing though. i found that when i turn my volume up .. it rattles the hell out of my gas cap door.. any suggestions in holding that in place?!
