Is this the best way to wire this system?

Also, i only have 2 pre amp rca outs, how would i got about connecting two amps with 3 sets of inputs?

You can split the front channel out of the head unit with RCA y-adapters to feed your extra amp.

Thats what I thought. Did a little research, looking at mono amps 400-600 rms that run at 2 ohms. Am I on the right track?
