They are, actually... though we're usually only on a landlocked river....

Before you cut into the boat, are the speakers magnetically shielded so as
not to interfere with your compass?

So I finally found a set of speakers that seemed like a good enough deal
and they came in last week. I'm wondering if anyone has any
input/experience installing speakers. They aren't flush mount which
needs I'll need to be cutting a few holes... some of my curiosity lies
in wondering if there's any certain saw blades one should use for
cutting fiberglass.... I was going to just drill a few holes to start a
hand jig saw... maybe tape up the area with duck tape to avoid
scratching.. other than that I didn't really know if there was anything
one should take precaution with.


I've used a RotoZip for this - much easier than a Sabre Saw. If its
simple glass it goes through it very quickly. Mine were in the cockpit
seats which had a 1/2 ply backing, so I went though 3 or 4 bits for both
holes. Tape the area with masking tape, draw your circle, and have a
helper with a vacuum to keep the dust down.


Also, though they weigh a couple pounds each, should I worry much about
providing some of support to the backing... like a brace to dissipate
weight on the fiberglass walls?


You shouldn't need support, but you could glass in some marine ply
before or after you make your hole.
