Here is my 0.02 opinion.
I think there is something truly magic about the combination of 4 Polk DB651s (cabin speakers - I think these are stock in your boat) and the Clarion xc1410 mini-amp (under $90 shipped from amazon).

Many here have used that combo with great results. It is NOT expandable as that amp is not bridgeable (albeit it is 2 ohm stable), just 4 channels, that's it. It is also not tun-able (well, it does have some rudimentary selectable filter settings, but who cares).
I tell you - the sound of DB651s powered by that little xc1410 is ridiculous. Even if you do not consider the low price. It sounds amazing, WAY better than it should. I don't care about specs-shmecks, just listen to it.
When I was playing with my setup in another boat, I temporarily checked the xc1410 against the WS HT-4. Now, that is about as completely off the wall comparison as you can imagine. To me, the DBs sounded
better with the xc... Natural, musical, fantastic bass, good volume. Of course I am not saying xc compares to ht-4! But the DBs and xc seem to pair up so well, it is supernatural.
If you are looking for a very inexpensive way to get a super nice sounding 4-speaker cockpit stereo system - I do not think you can do much better.
The only drawback of the xc1410 is relatively rigid/poor connectivity options, all is hard wired. I do not care and usually solder all connections, or you can use low-output RCA, whatever. Install is simple, tuning - pretty much non-existent. Sound - f*cking unreal, for what it is.
Oh, and I would not spend any extra on the xc2410. 1410 has the same power, slightly better specs actually if anything, just not bridgeable or tunable, unlike 2410. But you will not need that for the simplest of the setups.
