bangbang, i think some of the guys have got it. you have two seperate issues. You did not say how you are getting the signal into the amp?I am curiouse about that. But lets look at what is called turn on thump or turn off thump. The biggest cause of this is as fusebolwer said, timming of turn off. what is happening is your factory head unit is turning off before the amp . does it do this if you turn the car off without turning off the hu. it it does not then make sure you are using the factory switched power wire at the head unit and just dont turn off your radio. just use the ignition to turn evrything off.

wen ever i turn off my car with my keys it DOES not make that sound. but i would like to fix it so i would be able to turn it on and off wenever i would like. is there something that i have to adjust on the amp or is it just bad wiring. the wires "amp kit" or wut evers is stock as well. wen i bought the car. i already came with it installed.. i just bought a new box and sub and amp to install it. so yeah do i need to buy a better head unit?

Someone let me know but could it be that he connected his remote wire to a constant 12v and his amp is staying on the whole time and thats why when he turns the radio off it makes the thudd and also thats mabe why his car battery drained cuz its being left on the whole time? Also mabe ran the rca and power togheter? Could this be a possibility?

bangbang, the problem is that when you turn off the factory radio the accesory power is still live and hence keeps the amplifier on until you turn off the car. There is no way to make it work the way you want it to. There is no out put on the factory deck that turns off when you turn the radio off. any aftermarket hu would cure the problem and would realy improve your overall sound.It can only sound as good as what you start with....

Just to answer Cybernerd, it is not likely that proximity of power wire to rca could ever cause this problem. as well if bangbang was using constant power on his triger line it would also make the popping noise when he shut of the car with the key.
