I'm getting a side by side tomorrow and am wondering if 2 wakeboard tower speakers will be good enough for sound on it? They will be mounted on the back roll bar facing forward and powered by an amp hooked to my radio. I plan on getting 2 6.5's for the front down the road. I'm looking at getting a pair of Rockford fosgate m282 tower speakers (unless something else besides wet designs (think that is the name) is better). It is their 8" ones as I figure they might pack a little more bass than the others. Just really wanting to know if only 2 will be plenty for now.
