Engine noise through speakers? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

hrc200x · 06-30-2003, 06:16 PM

I have a '84 GMC 3/4 ton 2wd. It has some sort of aftermarket tape player and I think the stock speakers on either side of the dash. The speakers make this terrible whinning noise that goes right along with when the engine rev's or slows down. Any idea's how this could be solved?

Also, yesterday the driver window was down in the truck, I got in the truck, closed the door and then the window broke, I think I will roll the window up before I close the door next time.

You have a bad ground, more than likely at the radio chassis. If not there, check all your other grounds. Don't just make sure they're tight, take them loose and clean them.....

while your checking grounds also check plugs and plug wires-- if the are not resistor type - change

Yes, you CAN do something. Go to radio shack and buy an engine noise reducer, just make sure you get the one with the fuse.

Check your ground inside, (best to run all stereo components to one ground to instead of separate, if possible, less likely to have problems)
Also, check the grounds in the engine compartment. There should be one from the cab to the engine, and one from the cab to the frame. One to the frame could be broke, or not getting a good contact and causing it to ground thru the engine.
