What are the issues with placement? Are you concerned about wiring runs, audio quality, or weather. On my H37C I put four inch West Marine brand speakers in the coaming either side and above the aft locker/seats. In other words one at the right ear and one at the left ear. These were the flush mount without covers. Nine years later the grills deteriorated. Bouncing around in the Atlantic we lost a tweeter on port. So two days ago I bought the exact same set. $30. divided by nine years is ? ? ? It's a Steve Dion thing, he amortizes every boat purchase.
