So when i turn off my headunit, i hear a loud pop from the rear drivers side speaker. its very loud, it sound like the speaker is about to explode. i checked the ground and i felt like it was in a good area. anybody got ideas?

Is the pop louder when you turn off the HU at a high volume level?

Are you using the factory Monsoon amp, or an aftermarket one?

Do you have any fans other types of electrically inductive coil motors running as loads? (like an actively cooled amp with a built in fan)

You might try putting in a capacitor:

What ground are you checking? There is a ground in the harness that he HU wires into that you should be using.

volume doesnt effect it. i turn it down all the way and it still pops. i am using an infinity amp to power the speakers.

i didnt check that ground. im talking about the ground for the amp.

Stinger makes something that supposedly helps, their "SGN21".

I have never used it, and I make no claims as to how well it does or doesn't work.

Popping is usually a small amount of DC potential which appears at the output at turn on and off. There should be no difference in DC potential at the speaker output terminals, ever. But a 'Pop' means that for a split second, there is. This can be caused by all sorts of things.

It can be internally generated, faulty muting circuits, the start of a fault in the output stage. If you have a friend with an amp you can borrow, you could swap it in temporarily and see if that eliminates the problem.
