Answer
Hi Mat.

Ok you are going to need a power supply, to power the amp up.you can use a regular car battery for this. the remote wire its the one that turns on and off the amplifier so you can conect this to the positive terminal on the battery and put a toggle on/off switch, and thats basically all you need plus some speaker wire, RCA jacks and conductor 8Gauge wire for the power and ground.

Hope this helps.
