Engine Noise/Interference through Tower Speakers

Anyone know how to diagnose or fix this problem? I hooked back up my tower speakers this weekend and the interference is so bad that I had to unhook them while out on the lake. It did this last year and still does it, thought it might have been my connections on the speakers so I cut out some clean wire and hooked it up, sounded great at the house without the engine running but on the lake it's just horrible. Anyone know how to fix it? I'd heard there was a cheap fix but not sure what it is or how to do it? I have the standard Kenwood stereo that came in the '05 Supra's. Any help would be appreciated. Thanks everyone...

Usually that type of sounds is feed back coming through a ground wire. Im not sure how savvy you are with stereos but I would check all your grounds first. You will probably get even better advice from jonyb or someone.

Usually a ground.

Is this something I should check at the amp or at the head unit? Have recently been thinking about replacing the head unit with the new one they're putting in the Moomba's.

Check your AMP ground wire..its the big black one ;-)

Could be that the amp has gone bad. Try powering the tower speakers with another amp, or power different speakers with the same amp.

jony, wouldn't surprise me if it was the amp, was a salt water boat and when I bought the boat the amp had salt water spots on it.

kody, appreciate it, I'll check out the wire. I'm horrible at most anything electronic, you all should have seen me trying to crimp LED wires, it's ugly stuff.

iw I have heard this is a common problem when running your POWER wires near your SPEAKER wires, you can hear the electric signal thru the speakers (this is called crosstalk). It could be something else too but I would check this first.

If it's so bad that he had to unhook them, there's a problem with the amp.

Did it not have that noise before you unhooked them? You said "hooked them back up". If it wasn't there before, and it is now, check any wires you've moved for pinches or the amp is bad.

I have four speakers on the tower, I only had two at the end of last season. It would make that noise more towards the end of the season but it never was completely unbearable. Well, it is now. I haven't changed any wires (other than to hook up the other tower speakers which already had wire ran). It may be the amp then. Do you think that maybe unhooking the connections at the amp, cleaning them up and reconnecting would make a difference?
