Car Forum / Honda Cars / July 200696 Accord EX (I4) whining through radio
A whine coming through speakers that increases with increasing RPMs. That is a bad ground or a soon to be bad alternator? Do you have an aftermarket stereo system in the car? Usually this happens when speaker wires or RCA inputs are ran next power wires going to the battery. As the RPM's increase you hear the alternator "whine". If you do have an aftermarket stereo system make sure that you run your power wires on one side of the car, and the speaker wires or RCA inputs on the other side or as far away as possible. > A whine coming through speakers that increases with increasing RPMs. That > is a bad ground or a soon to be bad alternator? > Do you have an aftermarket stereo system in the car? > [quoted text clipped - 5 lines] > power wires on one side of the car, and the speaker wires or RCA inputs > on the other side or as far away as possible. That, or what I've found to be even more common is a ground loop. This usually happens when there is an AMP or other signal processor and it is grounded in a different location that the radio. Usually running a good solid ground wire from all the aftermarket gear to the battery clears up almost all alternator whine. > A whine coming through speakers that increases with increasing RPMs. That > is a bad ground or a soon to be bad alternator? bad ground/some other wiring issue. if after you're done, it's still not perfect, look into aftermarket plug leads that have a spiral wound core - they clear up a lot of electrical noise. |
