Extremely Loud Popping

[_DjScrew_ 5,000+ posts]

have you tried just pulling the HU out, running a pair directly to the amp and seeing if the noise continues to happen?

I pulled the HU out, ran a pair directly to the amp, still pops when windows lowered.

RCA plugged into HU and disconnected from Amp = No Popping when Passenger Window is raised/lowered.

RCA disconnected from HU and plugged into Amp = No Popping when Passenger Window is raised/lowered.

So does this imply the only other reason is a faulty ground ?

I will try a new ground for the HU in the meantime.

I grounded the HU to a small screw hole on the very back of the HU itself.

I used to multi meter and it tested as a valid ground point.

I also grounded the RCA wires to this same ground point.

The prior ground point tested as a valid ground point aswell.

It still pops when the window is lowered/raised

What would be the next suggestion?

Its only the Red RCA wire that does this.

The white one plays music perfectly fine but only out one side of the car.

Just wanted to take a moment to thank everyone for helping me through this.

Probem: Sheared off speaker wire inside door panel (hidden) near window mechanism, was touching metal.

Solution: After ripping it out with a great deal of force, I ran some new wires in a different location.

It now plays fine, NO MORE POPPING !
