asked on Car has a low whining noise when pushing on on gas after install aftermarket radio
Hi, I replaced a aftermarket radio with another aftermarket radio. The original has no whining noise when pushing gas but the new one does. Im not sure what could be causing this since the old one worked fine. Could it be the wiring harness? I looked around and it states the power cable maybe too close to the speaker wires but not sure which cables they are talking about. If its the ones on the harness you cant do much about the distance between them. If its from the harness to the speakers I dont see how the old one works and the new ones dont. Can someone help?

Is your radio grounded to the car properly?

It has a black ground wire that is connected to the black ground on the harness coming from the stereo. Should this not be enough or should i ground it to some metal on my car instead?
I think you should ground it to the car.
ground it to the car and install a suppressor capacitor, some stereo are super sensitive and picks up the noise from the engine
Well, don't ground the wire. It is already grounding through the harness.
Find a screw somewhere on the radio and ground that to the body of car. Look for a mounting screw on the radio preferably and run a wire from that to a earth point somewhere in the car or a piece of body metal somewhere you can attach the other end of the wire too.
Check your aerial connection and make sure the connection is good. Break the connection and reconnect if necessary and move it away from any wires.

So its grounded twice?
Yep.
You don't want to disconnect the ground that is in the harness. That might actually be working OK. Just make an additional ground.

OK I will give it a shot and come back with results.
