Weird Noise in one speaker

[GeneralNoobzor]

I have an aftermarket head unit and speakers.
When I first got the head unit it would make this noise, previous one did not.
Added an aftermarket amp, this is when the noise started happening.

It only happens in my left rear door speaker. Sounds like a space ship.
Static, high pitch frequencies, static burps etc. Only lasts a few seconds.
Rarely occurs

Happens at 0 volume, happens at max volume but the sound is not amplified.

What could be causing this?
Bad ground? (o awg ground)
Bad Wiring?

Not my patch chords - Monsters (I have tried 3 different sets)
Big 3 upgrades'
Ground is good, on amp and head unit.
Amp is not touching vehicle chassis.
Power is on one side of the vehicle, RCAs are on the other.

Not sure if head unit or amplifier

Help me out guys! Thanks

Is your power and rca's ran on the same side?

Do you have the gain all the way up...turn it down and see if it stops.

As said before me...RCAs and can pick up interference if ran close together.

If neither the above. Check grounds on amp

RCA s are ran on opposite side of the vehicle from power.
It's not my amp ground.
Amp is not touching vehicle chassis.
It's not my RCAs.

well, switch out the rca cables and see if it makes a difference, or you can swap the speaker wires around on the channels and see if the noise follows the channel in the amp, then you would know the amp is bad

its weird that you'd only get interference in one speaker only

I guess I will tear apart the center console tomorrow! I have already tried multiple RCA cables, and it isn't those.

what harness do you have for your radio?

also its possible that theres something wrong with the rca's in the head unit

Harness for my radio? GMOS-04 with Steering Wheel Controls. And an amp bypass for the speakers

Perhaps bluetooth is what is causing it? Sounds like mine:

nvm on the harness, forgot you said its all aftermarket

but its possible bluetooth could have an effect on it, not sure why it would, but anyhting is possible, lol

the other thing is are you sure the noise is coming from the aftermarket speakers and not the stock tweeter, i have a buzz in my stock tweeters cause they still have power to the amp which is still turned on with the bose amp, i never disconnected the stock tweeters

I have listened, and listened and followed the noise to the rear door speaker. ONLY that speaker. Besides, my tweeters are aftermarket homie.
