Question about JBL PB10 Subwoofer
I have a JBL subwoofer model PB10. I had a power surge at my house and now the 1.25A slo-blow fuse has blown. I have replaced it with a 1A slo-blow fuse and it blows. Any suggestions outside of sending it to a repair shop?
make sure you have the speaker connection right if you do then it is a ground problem try plugging it in a different outlet

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.
