My first question, is the woofer and amp working as designed. 2nd, is the (entire) system properly tuned? 3rd, is the amp's output maximizing the woofer's power handling?
I realize you may not know the answers to all of these at this moment, so it more food for thought, then me actually waiting on the answers. This is how i would approach the boat before making any equipment changes.
The revo-10FA is no slouch. Show me a marine 10 with similar specs. With proper wattage and a proper tune, it makes for a solid setup. Is it going to compete with a 1000W 12" in a ported enclosure? No, but neither will a Honda Accord V's a Corvette.
Ive never measured, but by the eyeball, theres not enough room to upgrade to the 12FA. Thats about 1.5" difference in diameter. The huge hurdle I think, is getting an enclosure back there. The only way this makes sense, is if you went with a new 10" woofer in a ported enclosure, or 10" woofer in a sealed enclosure with an RMS that 2-3 times that of the revo-10FA, and then fed it that additional amp wattage. At that point, your are going down the over the top highway
