I have a 19.5 open bow with limited floor space. I have a decent sound system as is, however, I am wanting more. Mainly because we are usually out of the boat on the beach a lot and makes it difficult to hear much if any! I am wanting to build two separate boxes with 10" subs and possibly some midrange/ tweeters loaded in it also. I've searched around a little with minimal success. I was thinking along the lines of the 'old' truck boxes that have 10's, mids and highs. That way they can be pulled to the front to the bow and will be able to heard without actually being in the boat. With that being said, a local stereo shop said that technology was outdated and was why I was having trouble finding such. Anyone have any ideas how to solve this dilemma? Also, I'm needing to keep the boxes fairly mobile as I store it at a marina with the possibility of theft!
