I posted this in the boat/accessories thread, but realize it should really have gone here. <BR> <BR>Proud new owner of a 97 ProStar here. <BR> <BR>I'll be the first to admit that I know almost nothing about audio, so I've been reading as much as I can. <BR> <BR>It seems the best place to start is with speakers and then work backwards to power them. <BR> <BR>There's already a decent set up with Polk separates around the interior, so I'm looking at the tower. I've been considering a DIY project similar to this: <BR><a href="http://www.wakeworld.com/MB/Discus/messages/65921/241023.html" target="_blank">http://www.wakeworld.com/MB/Discus/messages/65921/241023.html</a> <BR> <BR>I can't even find the Crossfire horn they used in the actual project, but I like the schematic at the bottom of the post. Eminence speakers are pretty affordable, so I'm thinking about this: <BR>4 8" Eminence Beta-8A's and 2 Eminence PSD2002/LT-250's in a similar enclosure. <BR> <BR>I would skip the down-facing speakers in the enclosure that was pictured. Thoughts on this? <BR>Decent sound quality? Would the passengers still be able to get good sound from the interior speakers?
