Thanks for posting that list. I've been wanting to build a system for my boat, and your list looks like just the ticket. I've been wondering about using a Bazooka tube, given that most other folks on this board go with a custom enclosure. I've just put in a new head unit, but my speakers are pretty rough. I think replacing them and then adding a small 4-channel amp, in conjunction with the Bazooka will really help improve things.
