i was setting up my boat this weekend and ended up working on the radio at bit. Trying to get it to sound good. I have the fusion head unit with 10" wetsounds on the tower.

The sub barely makes noise, just vibrates, and there is a serious lack of tuning available on the radio itself. Any recommendations? any help on how to get this to sound better? i had an order X2 with JL Audio that sounded about 10x better than this setup.

All i can find in the radio is Bass, mid, treble, and zones..
