Nice Little Sub....
Crutchfield Customer Review (What's this?)
Installed two of these in my pontoon (2017 Sylvan 8520) and they bump pretty good for 8" subs. They are mounted under the seats which dampen some of the thump, but I can't complain. I was looking on going the 10" route, but the space wasn't available for those size subs on the boat. The subs paired with the MB Quart MA1-440.4 amp.
Pros: All-in-one sub upgrade. Mounting brackets with straps.
