Question about JBL PB10 Subwoofer

1 Answer

Fuse blows when i plug in the subwoofer the fuse blows I noticed the other day my Sub was not working, so I check the fuse in the back and it was blown. It was a 3.125 Amp fuse, so I went to the store, but they did not have the 3.125 Amp fuse, they had a 3 & 4 Amp fuse, so I tried the 3 Amp fuse and it blew as soon as I turned on the Sub, without having any audio playing. So now I am stuck and not sure what I should do being that I have not been able to find the exact fuse match. Would a 4 Amp fuse harm the Sub? Mahalo!

Both 3 or 4 amp slow blow fuses are suitable replacements for the 3.125 amp subwoofer fuse.

It could be that the subwoofer is blowing the fuse because the one you installed was not slow blow.

But, more likely is the subwoofer has a short in the power supply which is causing the fuse to blow.

You may have blown a fuse, check those to make sure they aren't blown. Verify that the connections are in place again and make sure the settings on the amp are correct as well.
If the fuse isn't blown and the connections are secure, I would make sure that the wire that you have ran from your battery is within the specifications for use with your amplifier.

Sub-Woofer blowing fuses.

You should open it up and look for a short. Usually, an exposed wire is touching metal. Wrap the wire with electrical tape and look for a ground wires that are loose. That will blow fuses too.

Fuse blows, replaced the two capacitors and it still blows fuses... sub is fine and not blown...what else could it be??

If your sub is made to be used in other countries check to make sure it hasn't been switched to a different voltage.

Klipsch ksw subwoofer wont power on

The power supply switching transistors are likely fried. Dangerous high voltages involved. I would remove the plate and send it to Klipsch for repair.

Subwoofer

Repeated fuse blowing generally indicates a blown power supply, or blown output stages or both. One thing to do is be sure that you have replaced the fuse with the correct type. A T stamped into the metal of the fuse near the rating, indicates sloblo or Time Lag fuse. A fast blo fuse, may work once, or more times, but will never replace a sloblo fuse in this type if unit. Good Luck, hope this info helps, don't hesitate to hit me back here for more help :)

Subwoofer just stopped working. There's power but no sound.

I have the same problem. My guess is that the subwoofer coil is messed up. You MIGHT have to get it recoiled. But before you do any of that get someone with a sub to play their sub in your car, if it works.... then your sub is messed up, if not.....then your amp is messed up ( trial and error ). Today i noticed my subs rubber surrounding is crooked, that may be the problem for me. Also when I press down on the sub it makes a sticking sound, like something came loose. So once i get everything opened and out ill let you all know the solution. Good Luck!
