RCA cables between amp pre-out jacks on the back (FL, FR, RL, RR), and the remote turn-on wire to the amp's remote turn-on input. Set your gains properly, and you're done with the HU<->amp interconnections.

If you also have a sub amp (or are running channel 3 & 4 bridged to power a sub) you need to turn on sub output and choose a xover & hpf as appropriate, but I'm guessing you're just running four speakers.

Obviously the amp also needs its own power and you need to hook the speakers to the amp, but that's another story entirely.
