Well, here's my setup (so far). In the boat I have 4 Polk 6.5's mounted. I also have 4 Polk 6.5 Tower speakers and a 12" Polk momo sub. To power this stuff I have a Clarion APX480M (4 channel amp). and a Rockford Fosgate P5002 (2 channel amp). Without purchasing more stuff, what is the best way to set this system up (i.e. which speakers to what amp, how many batteries, and any other recommendations) Down below are all the specifications on all the stuff in case it will help with your recommedations.
