Re: Which volume control to use?

["Robert L Bass" <robertlbass@xxxxxxxxxxx>]

Use Russound impedance matching volume controls.  They'll need to be
protected to use them in a marine environment though.  You might use
polyurethane or ACF-50 spray (try Sporty's Pilot Shop) to keep moisture out
of them.
