I have a 21' bowrider and plan on redoing the stereo system. Getting
a marine Amp, Subwoofer, Headunit, 4 speakers.

Question:

I plan on getting a 6 channel AMP anyone have any experience on
mounting, as far as where? I was going to put it in a compartment
that really doesn't get airflow but is somewhat ventalated, does the
amp need alot of constant airflow? The subwoofer is going to be in
an enclosure and non-powered.

Any help is appreciated.



There is no such thing as a "marine stereo". Putting a white face on a
black faced car stereo that's wide open to the water doesn't wash, so to
speak...pun intended. None of these car radios sold at marine stores is
waterproof, so treat it like you would any ol car stereo and mount it
way up inside the boat so it never gets wet unless the boat sinks. Even
then you'll be hard pressed to keep it from getting wet.

Well, I agree that some stereos labeled "marine" are not worthy of the
name, but there are those that DO deserve the name. Being "Marine"
doesn't have to mean something is submersible. It means that it is
designed and constructed to hold up in a marine environment. That
means things like careful choice of materials for mechanical parts,
and conformal coatings for circuit boards.

In the case of electronics, it doesn't mean water tight or water
proof. Just a resistance to corrosion in a humid environment.

For that matter, I've seen "marine" speakers that are totally
waterproof, but are open backed. That means that if you get pooped, or
knocked down, you may have some instant 6 inch diameter holes in your
cockpit leading into your boats interior. Not good.
