I have a 1993 Ford E-150 hightop conversion van fully loaded 140amp alternator,13 inch Tv ,Vcr.

I have added the following...

1.Panasonic CQ-DF802U Head Unit

2. Soundstream Rubicon Lil' Wonder 4 Amp

3.Farenheit DVD-5 Player

4. Six 100 watt Soundstream 5x7 3way speakers

All the wiring is fresh 8 gauge power good Rca cables good ground all new speaker wires also. The system has a whining noise when engine is running , mostly noticed when reciever is on Aux and playing DVD through it. The noise seems to get louder durning acceleration. I have tried filters on the Rca cables in different locations and no difference. I have also bought high dollar Rca cables and no difference.

I am sure I forgot something any help would be appreciated, Thanks Bear Alternator Whine Noise, Help ! -- posted image.

I moved power away from other cables and redid the ground several times to different points and diff wire also. I am pulling my hair out.

Thanks, Bear

Are you running your signal cables down the opposite side of ur ride to the power?? And make sure ur ground point is nice and clean ie. sand back any paint work.

did you use any RCA connectors? like femlae to female, or male to male to change the input of an RCA for the video system?? also, are you using an FM modulator to get audio from your DVD player?? if you are using an FM modulator, make sure it isnt touching any metal, and make sure it is grounded in a noise free spot, and if you are using and barrel connectors for the RCAs get some good onces and not the onces that are 25 cents each, u are just bugging for noise then... anyhow, hope that helps.

Is that the Panasonic with the face that has graphics? If if is it could be the stereo. I had a similar prob;em with one like it, I think it's the high intensity discharge face that causes that noise.

On the subject of grounding to eliminate "engine whine".Can you use one of the mounting bolts for the seats?

I'm watching this thread very closely, since I have a similar whine coming out of my system.... so far, the grounding solution is the most promising, even though I sanded down to metal...

Let's hear more ideas!

:o)

In order to trouble shoot noise you have to isolate where the noise is coming from or wher it is being introduced into the system. You need to disconnect everything from the source unit except for the amp. Start there, see if the noise is there, then piece by piece start reconnecting your accessories until the noise comes back. Then; say for instance it is the DVD player, try to isolate it by running a pair of rcas directly from the dvd into the headunit without installing them into the vehicle, either outside the car or over the seats, if the noise still is there then try a different power and ground source point in the vehicle, if you still have noise, then hook the power up to a totally separate battery or power source that is not connected to the car and see if you still have noise. Once you have identified the noisemaker it will be easier to try and correct the problem, rather than just sticking a bunch of noise filters on you entire system and hoping that it gets rid of the whine. Also keep in mind that all manufacturers don't use the same "standard's" when building products and sometimes you might get a product that was built without using the best methods of isolating componentry, circuitry, power supply, output, etc directly from the manufacturer, just a thought.
