he's talkin about when you just turn the car on, or just turn the accessory on, then turn it off, the subs go POP! real quick, as if they're releasing power....

I have never seen a direct answer to this question so I can't help you out bro.... do you have a cap in your car??... This happened to one of my friends setups... never figured it out.

ground issue!

if you're talking about the amp's ground, i have it fastened straight to the chassis, but the screw goes thru the plastic covering the chassis, and in between the plastin n chas theres a washer.

as long as the terminal is directly tightened to the chassis you will be fine, BUT, then you'd have to make sure the paint is scratched off for a solid contact

Sounds like a ground issue imo.

not the amps ground but the headunits ground.

i have the amp hooked up to the hu from the hi input plug. 5 cables come out, the + n - left n rights, and the ground cable. but this is from the high input, i already have the amp directly connected to the chassis
