That sucks man. Skiers does a TERRIBLE job on ttheir stereos. I started swapping speakers out and ended up rewireing the whole boat. An 80k boat should come with top of the line interiors and your choice of HLCDs or strong coaxials.

Arrrre they puting a box on the their sub yet?

Sorry for the hassle. I can promise you a day and night difference if you make some swaps.
