I get 12 volts from the yellow/red wire, but nothing from the red wire.

When I unplug and replug the power plug on the sub, it makes a 'fut' noise, so I wonder if it's just knackered! Will attack the plugs with some switch cleaner and see what happens...

Thanks so much for this guide, it has vastly improved my day!

The sub has Audio feed from the speakers and two voltage supplies. The yellow is a switched live via the ignition, and the red is an on signal 12v if you like from the stereo, bit like a relay takes its main power from the battery and the stereo powers it on and off. If you have no 12v on the red your sub wont work.
