Moore Base

Ok, this one is easy. First of course you need a stereo and battery but then;

Go to Shucks Auto Supply or similar and but a cheap base tube. I got mine for $17

Then go to Radio Shack and get an old mechanical crossover (you can see it pictured below, mounted just under the Base tube), or a 10 Mili coil so you can filter out a bunch of the treble without using an amp. You can always go and get a small amp but this will be a bit heavier (not much) but it will also double your battery power usage, not good in a boat without a motor to charge it.

The Set up:

I have a stereo mounted under the cockpit floor, inside the boat and 2 speakers in the cockpit. They are wired on the front set of speakers. I took the rear set of speaker wires and bridged the power from the Stereo to the crossover then ran wire from the crossover to the speaker. You must make sure that your stereo can handle having the speakers bridged. This means taking the positive from the left side and the negative from the right side to power the base tube (or visa versa). If your stereo will do this you’ll have more power at the speaker, if it won’t it will blow a fuse etc… so make sure your stereo is bridgeable if you do this. Other wise just run one side (left or right) to the crossover.

I mounted the tube directly under the cockpit at the aft bulkhead so the base will resonate throughout the back of the boat. All of this weighed in at 4 lbs so it’s not much of a weight issue.
