So... Fitted a sub/amp for lol's.
The blue/white cable is what I understand to be remote so I spliced into it and T'd it off to the amp, it provides 2.3 volts but fluctuates between 1~5 volts as music plays.
It doesn't seem to do anything so I've plugged the remote cable into the red/live on the stereo so basically as long as the car ignition is on the amp becomes powered.
Ideally I want it setup properly...
Any suggestions?
Cheers!
