Default alternator whine in speakers

ok i have checked all wires re ran my rca's grounded rca's checked grounds. the speakers make the sound even if i just take a rca cord plug it into amp and hold in the air. the only thing i have came down to is it is the alternator. is there anything i can do that may help or do i just need to buy a new alternator?

It's not the alternator....

IF it truly is engine whine, then you do not have a common ground.

Not all electronics are effected by this.

join all grounds to all audio equipment including HU to the same point. Battery grounds and all.

Default Re: alternator whine in speakers

the source of all electronics is the battery. Get as close as possible to that if not on it.

Also, for testing, you can leave the existing wire there and add more from it to the source by using temp wire or jumper cables.

thats the thing originally it started out of no where so i upgraded all of my grounds and problem was still there. idk what else i can do to eliminate the sound i know some times the alt can cause it because of it failing. i do know that it has stopped charging a couple of times.

Do you have a dedicated ground cable ran off alt to same ground point your front battery is grounded to?

Also is front battery ground super tight?

maybe just get a hu with hd? It's amplifying the fm signal too much I'm assuming

If there is no ground cable for the antenna, then the base of the antenna is the ground. Scrape around mounting area to make sure clean installation. Extend ground if necessary to ground at battery.

If antenna is internally damaged, we have HD antennas that converts analog signal to digital to rid noise. If noise still exists with these, its due to poor grounding location. You will need to use remote wire for these and possibly work above headliner as it mounts where rearview mirror is.
