Well the amp is where I mentioned.  In the starboard storage compartment under the bed.  Mine is only a two channel amp with four speakers wired up.  The RCA jacks are plugged into Zone 1 on my Fusion RA70.  Since all 4 speakers are in the cockpit this really doesn't matter.  Check the wiring on the amp.    If it's two channel, like mine, all 4 speakers should be wired in parallel (2 rights & 2 lefts).  Otherwise there should be another set of RCA cables.

Thank you! Will be on the boat Monday, so should be able to sort this out.
