Noise over speakers when engine running.
Hi there,I am experiencing some interference over my speakers when the engine is running.
I was having problems with the head unit switching off from time to time so I decided to power up directly
from the battery with an in line fuse but after that there was no more switching off but this engine
sound interference,could it be that maybe this power cable is too close to the cables running to
the amplifier,I want to remove the head unit but just looking for some advice so when I remove
it I know what or where to look for a solution.
Thanks.....

Re: Noise over speakers when engine running.
Grounding issue and power cables running to close to your RCA's, make sure the head unit is grounded properly as well.

Re: Noise over speakers when engine running.
RCA's and power cable on the same side of the car?
I always run the power cable on the side where the main wiring harness is and the RCA's either down the center or on the opposite side.
If they are already separated, then what Headunit is in the car?
I once had to ground the outer of the RCA's to the headunit. It was a JVC deck.

Re: Noise over speakers when engine running.
More than likely this. Even more likely if it is a Pioneer HU. Cable from the back of the HU to the body to ground it should help.

It is a pioneer HU,they are separated,I don't understand what you mean by "ground the outer of the RCA'S to the head unit?'amstel18 wrote: ↑Tue Aug 07, 2018 8:13 am RCA's and power cable on the same side of the car?

Thanks for the responses guys I will try and put a good ground on the HU and take it from there.

Re: Noise over speakers when engine running.
Crude way I did it was take some flex and strip it and then wrap the copper strands around the outer part of the RCA and then the same on the other end and then take one of the casing screws off at the back of the deck and ground it there.mellos wrote: ↑Tue Aug 07, 2018 10:55 pmIt is a pioneer HU,they are separated,I don't understand what you mean by "ground the outer of the RCA'S to the head unit?'amstel18 wrote: ↑Tue Aug 07, 2018 8:13 am RCA's and power cable on the same side of the car?

Re: Noise over speakers when engine running.
If connected incorrectly originally, I think an IC or something in the HU blows and then needs the additional grounding to sort out that interference.

Re: Noise over speakers when engine running.
Wrap the wire around the outer metal part of one of the RCA's and then to the back of the cage of the HU. So not the metal point that goes into the HU, but the outer metal part. If that makes sense.mellos wrote: ↑Tue Aug 07, 2018 10:55 pmIt is a pioneer HU,they are separated,I don't understand what you mean by "ground the outer of the RCA'S to the head unit?'amstel18 wrote: ↑Tue Aug 07, 2018 8:13 am RCA's and power cable on the same side of the car?

Re: Noise over speakers when engine running.
Hey bud it's somewhere on the circuit board, I honestly don't know where or what they look like. Some of them look like a diode and others like a tiny wire strand - whenever I had this issue I just grounded out the rcas, didn't try repairing or replacing it..
Google the model number of ur radio, eg "xxxxxx Pico fuse" some1 must have done a repair at some stage
