Feed back in my boat speakers?

Question

I have engine noise in my boat speakers with the boat is running. how do I fix this problem?

Answer 1

i had this problem also, make sure you have good grounding to the unit or maybe your ground wire is not big enough

Answer 2

If Capt Bill's solution doesn't work, you will have to add a noise suppression kit to your ignition system.  They are available at your local auto supply shop or Radio Shack.

Answer 3

It's not really feedback, what you're hearing is alternator whine.

Try grounding the stereo directy to the negative terminal of the battery using 14 ga cable and your power supply cable a shielded one from your breaker panel. Sometimes this will eliminate the problem, failing that you'll have to go with a noise supression choke to your stereo.

Good Luck!

Answer 4

You need to use resister type spark plugs and wires.
