I purchased an in-dash CD player that plugs into the back of my bose receiver a pretty nice set up. The problem I am having is that once the CD
player is switched on and playing I am getting that whinning accelarator noise. I have tried everything, shielding etc. Still no luck. Can anyone help me??

Bad Ground

 

Ok,

I have tried to ground this thing everywhere. Should I run a separate ground for the player and the receiver even though they are already grounded to the holding brace? and if so, what is the best place to run the ground too?

tks,

jay

 

try grounding near the the shifter, just remove the plastic cover and there should be four bolts around the shifter, i used these for grounds on alot of my accessories in my car

 

Where did you buy that single CD player, is it an OEM Nissan???

 

try sanding off any paint at the grounding point. it'll give you better metal to metal contact.

 

The bose system amp and circuit boards have gone bad. Especialy if the noise is very high pitch. Same thing that happend to mine.
I took the front speakers out and apart. Removed the circuit boards and wired the system direct(using factory wiring) to the new stereo.
I'm betting that it's not the alt.
Mail me for more details as I've been through this.

thanks for your help...I will try to get it done today.

The player holds 6 CD's a very neat set-up. I think it was
OEM, but I will have to check. I've just had it sitting in my
dash until I was able to get some more info on this grounding
problem.

Scott, I don't believe my AMPS are bad, they were repaired prior
to me installing the player. Could it be my Alt?

run a ground loop isolator between the new cd player and the power wires connected to it, problem solved.
