Basic Wiring diagram for Headunit to amp to sub.

[TbM]

ahh ok thanks again guys. im hoping ill be able to cheat and connect the cables by putting my hand through the empty din slot below the HU, does the remote cable plug in? or do u splice it and put it in a hole that makes contact via pressure (like the way the power goes into the amp). because atm the RCA cables have a blue wire running parallel (tape on to) with it but not plugs on either end.

Remote is just a small gague wire, have to strip the ends on your harness and remote wire and solder them together(can just twist and tape if your lazy) other end goes in your amp.
That blue wire is your remote, it wont have plugs.
