Im looking to hook up 2 amps, one is a kicker 2 channel 200 watt amp, the other is a 4 channel rockford fosgate Punch 500, what is the best way to do this, the boat is an 87, 357 formula, twin 454's, 2 batteries,

I PM'd you back by the way. Need a little more amp info from you.

Were do you plan to put the amps? How long will the wire runs be? What ohm loads on the amps

What exaclty are you trying to hook up speaker wise?

I run my amps straight to the batteries. The turn on wire goes to the back of the radio, which is powered from the boats elec system. You will need a set of rca jacks from the head unit going into one amp, and a set of rca's out of that amp, into the other amp. Depending on the amp specs, sounds like the Kicker can be used for the subs, and the rockford for the highs.
