You also need a remote on/off +12v to turn the amp when you turn the ignition on.
The picture shows where I found the (+12v) remote 'turn-on' source connector on my X. I found this connector somewhere under the CD changer on the left side of the trunk. You may not have the exact same connector so use a voltmeter to test each wire to find which one works with the ignition.
