Just a heads up, thats a good price for those speakers. I used to have bazookas on my boat before i upgraded to JL's. You could barely hear the bazookas while wakeboarding, and it turned up too loud, they would be obnoxiously distorted. If you are looking to just 'some' sound and not quality sound thats a hell of a deal. If you are looking to get a loud setup, hear some tunes while boarding, i would stay away.
BTW. i had an alpine 450w amp pushing them at that time.
