Your stereo speakers under the seats, did you have to cut a hole to
mount them? Can you access the rear of the speakers from the
lazarette?
A couple of weeks ago you posted to the Rhodes list about replacing
the fixed ports with opening ones. At the moment, my attention is on
installing stereo speakers along the cabin wall and I'm wondering how
much depth you found between the inner and outer walls of the cabin
top. The speakers I'm thinking about require a depth of 1". While
you had the port out, could you tell if there was enough open space
to run wires fore and aft through the cabin wall?

I found that there was less than 3/4" of depth between the inner and
outer cabin walls with the lower portion of the opening a bit deeper
than the upper portion. I had to make several passes on my jointer/
planer with the treated 3/4" thick wood blocks I cut for supporting
the new hatches on both the upper and lower portion of the openings.
I don't know what types of speakers you plan to install but I can't
recall seeing speakers with the cone and magnet this shallow. If it
works for you please let me know as I've been thinking of installing
a stereo system in our boat. I have a hard time going for any length
of time without listening to music, especially Stevie Ray or Carlos
Santana (See Milagro).

The photo web site has pictures that show Rhodes 22 stereo installations.
The 1st two photos show my stereo installation down in the galley. The 3rd
picture shows my cockpit speakers mounted on the transom.

I used 16 gage shielded twisted pairs for my speaker wires in order to
absolutely eliminate any possibility of interference to the compass &/or any
other electronics on board as well as prevent any problems with 60 cycle hum
&/or ignition noise in the sound system. Stereo systems can be both the
cause & the recipient of interference! The use of shielded twisted pairs
for my speaker wires did not introduce sufficient capacitance into my system
to cause a problem. The sound from my stereo system is absolutely clean of
any spurious signals & I don't get any interference in any of my other
on-board electronics despite running the speaker wires all over the boat.
However, you should check the specs for your system before you use shielded
twisted pairs for your speaker wires. NOTE: I did not 1st try installing
the speakers with plain wire as some of the others have done. You may be
able to get away with it or then again, you may have a problem. I used
shielded twisted pairs for my speaker wires as a simple matter of good anti
EMI practice. Life is too short to constantly have to troubleshoot & redo
systems. I'd rather be out sailing & listening to the stereo on my boat.
The main reason for keeping maximum separation between the ship's compass &
the speakers is the powerful magnets in the speakers. Try for at least 6
feet of separation between the speakers & the compass & more is better.
Enclosed below are copies of a couple of previous posts re this subject
that, I think, answer all of your questions:
Where is your ship's compass mounted? Remember, you don't want the speaker
magnets anywhere near the compass. On Dynamic Equilibrium, we have the
cockpit speakers mounted in each corner of the transom facing forward. The
cabin speakers are mounted at the aft end of the V-berth facing port &
starboard. These locations have worked well for 13+ seasons & counting. As
far as the stereo unit itself, there is a picture of Dynamic Equilibriums
galley on the photo web site which illustrates the installation up above the
galley counter top.
