David, I've looked into replacing the speakers myself and found a few items to consider:
1. The existing (crappy) speakers are fully contained unit, attached by four screws to the bottom skirt panel.
2. You can replace them with any Marine speakers, but you will need to consider how to mount them. One way is to cut holes in the skirt big enough to mount a good size set of speakers (5.25"?) But, doing this will expose the rear of the speakers to rain, mud, dirt, etc. Having said that, one could also purchase covers for the speaker's backsides
3. Another option is to mount the speakers into some kind of pods, then mount the pods to the skirt. The only downside I see, is that the speakers will stick out from the skirt a bit more. Below are some links I've found good for comparison purpose:
Angled Speaker Pods Speaker Adapters 6 5" 6 1 2" or 5 25" Speaker Mount w Flange | eBay
Amazon.com: Pyle PLMR51B Dual 5.25'' Waterproof Marine Speakers, 2-Way Full Range Stereo Sound, 100 Watt, Black (Pair): Car Electronics
I'm leaning toward the Pod solution, rather than cutting holes in the skirt panel. But, it's a bit pricier, as you have to buy the pods too.
Good luck and let me know what you decide.

Does anyone know where I can Find another pair of them so I can mount two more towards the rear? Thank you
