Speaker engine noise problem
Hi guys just need a bit of advise regarding the noise my speakers make when the engine is running. The system is installed in a wakeboard boat and comprises of 2 speakers on the wake tower and an amp under the dash. It also had a JVC stereo and clarion speakers that came stock with the boat. The system works perfectly when the ignition is on and the engine isn't running but as soon as the engine is running a buzz can be heard through the wake tower speakers but not the original speakers which are not wired up through the amp. The engine is a 330hp mercruiser V8 inboard. Any ideas on how to fix would be greatly appreciated.
Ps due to the boat having no real metal frame the amp is wired directly onto the battery, ground and all.

You still didn't tell me what make and model of amp this is. I have a funny feeling the amp is the problem. Easiest thing to do, borrow an amp from someone, temporarily hook it up to the same wiring see if the problem persists, if it doesn't change, your next step is to replace the RCA cables or to reroute them.

I wi give it a go tomorrow. I don't think the amp is the problem because as I said the speakers and amp work fine without the engine running, I think the alternator could be it because it changes pitch with the engine. And becuase it's wired directly onto the battery this would make sense because the alternator produces more current at higher rpm... Or I may be completely wrong altogether, wouldn't be the first time

Welcome to installing audio systems in boats ! (LOL) Friendly word of advise for you, always put your systems components in a boat on an easily accessible area.

I have a funny feeling the amp is the problem. I read some forums online about this amp and not one person had anything good to say about "Powervox" amps. So in all seriousness eventhough it was a complete pain in the *** to install I strongly suggest removing it. RELOCATE IT TO AN ACCESSIBLE SPOT, as I said before grab an amp from someone you know and temporarily hook it up to your existing wiring and see if the problem is still there. Another thing, if your only running a pair of speakers you only need a 2 channel amp. In boat audio applications you want to keep things as simple as possible for the simple reason of current draw.
