Popping is 2 bad capacitors on amp circuit. If < 3 years since purchase, covered by Polk. Mine was 4 years out. Cost $48 to get it fixed and shipped back from Polk.

Fixed PSW125 HearBeat Problem by replacing the main capacitor on the amp board.
Power off the sub. Push the reset then power back on.

Run 2 RCA cables from the two Purple connections on your Receiver (Labled "PRE OUT SUBWOOFER") to the Red and White connectors on the back of your Sub (it does not matter which Purple connecter you plug into either the Red and White)
Set the volume control on the Sub to about 75%, and keep the power switch in the "ON AUTO" position. To set the Low Pass value, look at the back of one of the front speakers in your setup, and note its frequency range (will look something like 100Hz - 17kHz). Set the Low Pass at a value slightly higher than the low value on the back of your surround speakers.
To set the phase switch, stand in the middle of the room with some music on (something with some bass, but not over the top bass) and have someone switch between 0 Deg and 180 Deg. Listen for which setting sounds "Louder and Fuller". This is the one you want. You will need to do this each time you move the Sub, as its position may change its phase in relation to the rest of your system.
Good Luck!

Yea, now its time to replace it! the magnetic effect is weaken which makes the very bass low frequency sound to be distorted! You should re engergise the magnet of the subwoofer or should buy the new!

Connect the subwoofer to an amplifier/audio receiver with the proper cables. Reply back with your setup so I can get some more information.
