Wakeboard tower speaker interference with motor?

Posted: August 31st, 2009 | Author: admin | Filed under: Wakeboard Tower | 2 Comments »

I just had some new tower speakers put onto my boat. I am getting noise interference with the motor when it is running. I have a control knob that adjusts the volume of the tower speakers separately. What do i do to get rid of the interference?
I believe it has something to do with the grounding.

Sell the boat or remove the speakers. Not a real challenge here. Better yet take the fool thing to the seller and have them fix it!

    You haven’t described the sound you hear as interference.

    If it’s a ticking sound that varies a lot with engine RPMs than you may have a defective spark plug or distributor cable or possibly a poor coil ground.

    If you hear a "whining" sound that also varies with engine RPMs and seems to get louder when you turn ON high current electrical accessories such as the air conditioning or high power search, then you have alternator noise.

    Ticking noise is often the most difficult to eliminate. Start by making sure all of your sound system cables are connected securily. Replace any cables that are way too long for the application.(Don’t use a 6 foot cable if you only need 3 feet).
    If there’s a long cable between your main equipment location and your power amp. replace it with a coaxial (RG/6) cable and adapters.
    Be sure NO sound system cable is within 3 feet of your engine. Finally,be sure that the power cables to the sound system are of the proper gauge for the amperage requirements of the system for both this type of noise and more importanly for "whining" type noise.
    If all of the above sugestions are followed and you don’t eliminate or greatly reduce the interference then have the engine’s ignition system completely checked out by an expert mechanic.He will either find a defective ignition component, a timing problem or bad ground. As a last resort, move any equipment located within 6 feet of engine to another location.

    Whining problems can often be eliminated by installing an alternator noise filter of the proper amperage in series with the Positive cable feeding your sound system. As mentioned above,be sure both the Pos. and Neg. cables are capable of handling the amperage requirements of the system.

    Good luck!!!
