u need to find the rms figure for the sub and find an amp that can put out close to that.

as wiring goes, a fused live cable from the battery and an earth. from the headunit u will have 3 wires to go to the amp. there will be two RCA leads with plugs on the end and they are pretty self explanatory when you see them. the third wire is often a blue one which comes from the back of the headunit. this will need extending to the amp where ever you decide to mount it. this wire tells the amp when to turn on/off

But what type of amp do I need? I presume when they refer to channels they mean the amount of speakers they can run??? If I got a two channel how would I power one speaker with it? Or is there a amp purly for a sub?

I do not know alot about ICE you see!!!!

rob, when you have a 2 channel amplifier, what you do is something called Bridging, it basically turns 2 outputs into one, is very simple

theres 4 speaker terminals on the amp right, like + - + -

you connect the sub off the first + and the last -

so you miss out the middle - and +

and thats that
