This is the first time I've used a relay, and I don't understand how to wire the thing up. It's got 4 prongs. One that is labeled 'common', one labeled 'normally open', and 2 labeled 'coil'. Tell me if I'm wrong:

'normally open'- gets connected to remote wire

'common' - ground

'coil'- one is for the 12v in and the other is the new remote wire that goes the the amps

?

You have it exactly reversed.

The "coil" is the part inside the relay that controls the switch. Therefore it gets connected to your trigger wires. Connect one coil terminal to your head unit's remote output. Ground the other terminal.

Normally Open connects to your supply of 12v power.

Common is the output to your devices.
