Pontoon speakers quit working

[Fuzzy]

I have a SeaWorthy am/fm cd player with four speakers in my pontoon boat that has worked well for two years, until now.

The radio/cd unit has power and works. I can play cd's and change the radio station but no sound comes from the speakers.

I have checked the mute, balance & fade controls. I have also checked and replaced the two in-line fuses. I get no sound or static from any of the four speakers.

It did rain between the last time it worked and now, but all the speakers & the unit are weather protected and have been rained on before.

I can't believe all 4 speakers could "go out" at once. I don't have an extra speaker to check. Any suggestions?

Try checking all connections. check at the speakers and the unit. If the connections got wet corrosion may have developed. This same thing happened to me. The connections at the speakers were corroded so I redid them and put a dab of silicone on the terminals. Hope this helps.

I had the same thing happen in my crestliner. The front 2 speakers were under the top, but the back 2 were exposed to the weather. One day the back two just quit working. The terminals were corrodid, I cleaned them up and now they work fine.
