Question about JBL PB12 Subwoofer

Sub Zero 632

The handles are loose. If I pull back the gasket the only screws that I can see, seem to hold down the gasket.

My question is about a Sub Zero 632 Fridge not a subwoofer. Your system must have automatically but it into the subwoofer section. Do I need to repost?

Fuse replacement


The fuse is integrated in hte AC socket. You'll need a small screw driver to pry up the part that talks about the power requirements. Check the online manuals for more details.

Sub works then turns off


You're dancing around the clues. The position of the monster cable seems to affect it. What shuts off - the receiver (need to know make/model) or the sub? Just connect the cable deep enough to make contact with the metal parts you can see of the clips and/or binding posts. Don't let any conductor touch more than one metal surface. Now what?

How is it attached - RCA cables or speaker output from the receiver? Need specific info to make a good diagnosis.

The time factor is curious. Again, what's turning off? The receiver? There should be no reason for it to overload since it just supplies either Line Level to the sub amp's Low Pass Input or speaker level to the sub's Speaker In terminals. Are you slaving your Front Speakers out the back of the sub or are they on the receiver? Experiment with them disconnected.

Jbl eon


the eon woofer is designed to fit the small frame of the inside cabinet. The EV woofers look too deep to fit but you can try. I do think that the built in amps were set to work with only the JBL woofers so there might be a signal problem using the built in amp. The eon face seems to have their own screws to hold the grill so if they aren't holding you can drop some cement to help hold the srews in place. The front does not allow removal of the woofer so it seems whatever you do should not effect anything.

A few more questions-
Does the sub hum without anything plugged into it except for power? If it makes a real loud hum almost a squeal then I think the rca cable between the receiver and the sub is dead shorted and needs to be replaced. If it's more of a low level hum, then it's a ground hum caused by many things, ie........the receiver and the sub being on different power circuits in the house.......sometimes diconnecting the cable tv feed as it enters the room while the sub is connected and humming to see if it stops........the easy fix sometimes is using a 3 to 2 prong ac adapter but lifting the ground on such a powerful amp could be a fire hazard.

Sunfire Mk II hum (different from greekboy post)


I had this issue a few years ago and the power cable from one of the inner terminals had come loose. It was still touching but whenever the sub would really pound it would jump off the connection and then reconnect causing it to hum. It was the most annoying thing ever so I finally pulled off the amp plate (super easy) and you could clearly see the loose wire. I had to use a good soldering iron to put it back on since it's a pretty fat wire. If you're not under warranty anymore then pop the back off and see if that's the issue.

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!

No LED light on PSB Alpha Subzero-i and keeps blowing fuses.


Others have had similar problems with the amp on this model. There is probably a circuit design error which causes some components to blow and as far as I've read, fixing it (or replacing the fuse) won't make the problem go away for long. Try contacting PSB or the retailer.

Since this is a sub I assume the sound is not coming from the speaker but is mechanical and coming from the amp in back. The tranformer can be the problem if it has delaminated or may be loose. Try removing the amp and tightening the screws. If there are rubber grommets to isolate the tranformer don't overtighten. www.pardigm.com for contact info and parts. They are very nice. If the noise is coming from the speaker then you are still under warrantee and they will replace it free.
