Problem with Subwoofer amp/driver ? Help !

[yxiang]

Hi there,

Thinks my sub amp/driver is faulty, give out a "pop pop...." sound whenever there is heavy bass and there's a loud "boom" when turning off the main switch. Did call the local service center, but the charges was like USD140. So now I' thinking iit's worth servicng or just get a new one? Hope someone can give some advice or help me in troubleshooting or repair it myself. Thanks for listening.

Good Day !

PS: my sub is 3 yrs old model PSW 202 Polk Audio.

It's not worth fixing. Buy a new sub.

I second that. It's time to upgrade. Consider this a blessing!
