[louis_23]

ok im slowly getting there with my sub and amp now lol managed to get alkl cables run frombattry/head unit to over end of car boot/subwoofer  next stage is connecting them i have connected my cable to head unit and back to my amp but a lil confused as it has a third wire what is it is this just an earth? looks like my perfetic paint skills below lol  and if so do i conect it to the bit on the amp listed REM.......

that can be used as the remote from the h/u to the amp
but to be honest it would be better to run a seperate one as that is very thin and they can break very easily

yeah it dose keep braking lol whats it actually do lol and where do i connect it to? what colour wire on head unit and where on amp? thanx dude realy appreciate the help

Usually a blue or blue with a white stripe. Maybe you should get someone who knows what they're doing should wire it up. You don't want to blow anything up

the point of the REM wire is to tell the amp when it needs to turn on. This is done by sending a positive voltage down the wire usually sent from the headunit. This means the amp is not on all the time and doesnt drain your battery.

Is there a wire on both ends as I was always under the impression that it is used to ground the shielding of the RCAs?

[deanpompey]

no its definately a remote wire....
