the remote wire comes from the headunit- if you have an aftermarket unit, it will probably need to be hooked up to the spare blue one

Thanks. but shouldn't the sub amp be showing power i.e. a light on even without remote hooked up !

Nope, 'cause it needs the +12v from the remote terminal to tell it to turn on.

Oh and don't get clever and bridge the +12v in main power to the +12v in remote, yes it will turn on the amp but if you leave it and walk away whistling at your success, you will soon have a flat battery, even if you aren't operating the stereo :)

Thanks dude! I'll be sure not to, the battery is a bit jaded as it is. Cheers for your help

Once you've sorted the remote wire, double check you have a solid ground if you have any further problems.
