When the replacement speakers arrived for the broken external speakers on our fifth wheeler, we had already cleaned all of the old caulking away and were ready for the install. After removing the tape that I had applied to keep the rain out, the next step was to clean the surfaces with alcohol to insure that the caulking sealed well.
Since the factory installer had put the speakers in upside down the first time, I made sure that they were placed as they were engineered to be. The above photo is the correct way. Here, below, is a look at how the installer had them placed.
Note that should the speaker cone break, water can easily enter the trailer.
So, have you got a potential “speaker leaker” ? It might be worth the time to take a look. If your external speakers are covered like the one below, it’s a easy check.
Loosen a screw or two and take a quick peek. It’s a investment in peace of mind !
