Thanks to all for the Help, actually im going to check the ground, like u say, also my Car is a Hyundai Elantra, and i think it have a 75 amp alt.
The ground wires i connected to the Chasis of the Seat, i dont know if it gets too hot, or what, but im going to check; also the sound just decreases, its nbot turning completly off, and the impendance its the corretc (i think), 4 ohm, for each amp, Thanks again for all the help, and keep replying, THANK U ALL

My money is on bad ground. Try to ground it to the chassis of the car too, if possible.

after that last post im gonna go with ground also....i never ground to the seat...its always best to strip an area to the paint and using a self tapping screw and star washer screw the o-ring (you have one on the end of your ground right?) to metal....

if it isn't going completely off, then the amps are not over heating and going into protection mode. I would go with the general concensus here and say bad ground.
