I have a 2009 21V, planning to upgrade my speakers before summer. Looking at either rev8 or rev10's. Was told the drop on Rev10's with adjustable mount is just at 14". This is hanging down to eyeball height or lower on my boat. It's ovever the seats, but I'm wondering if anyone else out there has these or the 80's mounted (about the same size I think) and any feedback. I'm worried about cracking heads on the speakers. We would probably just mount 2 of them, but our holes are already drilled probably 50% lateral to midline so they wouldn't be all the way out to the sides.
