Does Phoenix have a bow mount for a single 12” unit for the 721? Decided to run just one unit up front for now and add my other back later on.. I have a 9 flush mounted up front but bought a new 12” to replace it ..I was going to run a OTP mount for both, but have decided to run just the 12" for now and rather have something clean looking on the bow...Any pics? I know the 2017 and later boats do, but not sure about earlier years...
