SOURCE: Thump at the time of shutoff
The amplifier in the sub as with any other amplifier has a capacitor in it. Essentially a battery that holds a charge. When you trun things off such as subs or amps with a powerstrip instead of the intended on off button, the power supply has been cut, but the capacitor is still energizing the unit. So it catches the noise in the line.

In the industry - It is called "Turn-On Thump".
There are some manufacturers that eliminate components like noise filters on enry level lines to save money.
There is no way to lessen this noise without ripping the amplifier apart and having a technical knowledge of the way amplifiers work. It would involve hard-wiring a slow charge capacitor in the turn on line so it gradually builds power instead of getting it all at once.
Thanks for using FixYa - a FixYa rating is appreciated!!

More likely to be the Class D power amp module, but you should look through the service manual to make sure all the parts are installed correctly. My PB10 AMP module went out and you cannot get one anymore.
