Re: Speaker installation

Sorry, that was a bit uninformative..
They weigh about 2 or 3 pounds/piece.  They didn't come with back braces,
and they would probably mount ok... my concern is the shock of slamming over
wakes over time, cracking the perimeter...

"Features: * Rubber surround * Magnetically Shielded * Weather-resistant
woofer * UV impregnated ABS heat-resistant weatherproof grilles * One-piece
formed ABS basket* Recommended amplifier power 10-60 watts RMS, 150 watts
Peak * Requires 3.45" of mounting depth and 5.63" cutout diameter * * Dual
Cone: Mylar * Cone: Polypropylene * Basket: Durable and light weight ABS
plastic"

The link tells us nothing about the speakers other than that they *are*
flush mount.

No backing plate needed.

If they are exposed to the sun and sea spray I hope they are capable of
withstanding the long term effects...rubber surrounds and neoprene cones.

If not be prepared to be replacing them every year or two.

Sometimes cheap is not always the best deal.

Well, these ( http://tinyurl.com/692pp  ) are the ones I got.

They'll be going on either side of the walkway to the open bow (at cruise
the two rears can't be heard at all, really.)  I can climb under the dash on
either side with enough room to work, and water (though moisture might)
doesn't usually find it's way into that area..

Where on the boat are you installing them? Most speakers I've seen are
inappropriate for use in the cockpit, if that is what you are planning. Unless
they have a sturdy and solid enclosure, they are strictly for inside the cabin,
or maybe up high in a flying bridge. Speakers without enclosures in the cockpit,
instantly become large holes for water to enter if the boat gets pooped.

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.

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?

TIA
