How do i get the whining sound to stop on my car speakers?

Question

i had install a new stereo then after installed myself an amp. now my system makes a whistling sound how do i get it to stop?

Answer 1

first make shure that all the grounds are connected together.. that is the metal part of each unit.. that noise is possibly regenerative feed back.. so the input is much to high.. reduce the input to the amp and the noise will stop.

Answer 2

That means that the ground isn't good, check the grounding wire this most of the time gives a whining sound in speakers.

Answer 3

the source of the problem is the stereo. pioneer stereos are notorious for having grounding problems when theres a short or small static on any RCA and blows an internal fuse.

there are several ways to fix this. one is buying a "ground loop isolator" but will reduce the sound quality of your system. radio shack should have them.

another one is getting a speaker wire. in one end, connect it to a good ground source. on the other end, loop the wire around the outside of the RCA's that will be used behind the stereo.

notice i said outside of the RCA's. the outside part is what carrys the ground on them. the hole of the rca's is what carrys the signal. since the stereo does not have good grounding on the rca's, this will fix it very easy.

if you do this, try to do it as clean as possible.

ive fixed several stereos using the 2nd method cus ppl for some reason connect and disconnect the wires or rca's while the stereo is on. usually this will create static and travel to the stereo through the rca's and ends up blowing the internal ground fuse. the result is a buzzin sound when the car is on only. very annoying too lol and it gets louder if you step on the gas.
