So about a week ago, I got inspiration to do a quick and easy upgrade to my subs on the boat. I was running a pair of Infinity 10's with a 2 ohm load to my sub amp. Since the amp's 1 ohm stable, I decided to buy a 3rd 10" sub and drop it down to a 1.3ohm load and have the amp push out the full 1000 watts.
Because I didn't want to spend a lot of time or effort, I found a pre-made bedliner sprayed box and used that. My existing subs were installed without removing the foot rest. So while I could have hacked out the footrest to make room for tons of airspace, I wanted quick and easy. It was a little more work than I planned, because I had to remove the existing box and squeeze in the new box forward of it. But I utilized some of the dead space under the helm and the result is amazeballs. bass times 150%!!! Net cost was $169 and one evening of time.
So now I finally have bass that keeps up with the REV410s on the tower.
