So I have a 2007 Moomba Outback V. It has stock speakers and amps, all kicker. The interior boat speakers work fine (with a small amount of buzz, if you know why this is please tell ), they are hooked into a kicker ZX700.5. But the tower speakers are a different story. I got them working while the engine not on and is on land (lots of buzzing, but can still hear the music), but when the boat goes in the water and we are going all they will do is buzz.
The towers are hooked into a Kicker ZX250.2 amp.
Please help, I have been trying to fix this for a very long time and am getting frustrated.
