Question about JBL PB12 Subwoofer

1 Answer

I have been getting static from my subwoofer. I thought I had a blown speaker so I bought a new one. I hooked it up and there is still static. So now I have two good speakers. Anyway, I went through all my wiring and I think everything is good. I don't see any postive negative problems. I don't think the speaker will make any sound if those are crossed anyway? I have been reading that there may be a lose connection in my amp. So, I took that out and everything looks fine there too. You think I need to keep looking for a crossed wire, amp needs repaired, or the whole thing is junk?

    Is the static more like a hiss or a dirty crackle. Is it 100% of the time, or only when playing a signal. Is it dependent on the input source used or is it with everything.

I have a similar problem, where a power surge zapped the power supply on the power section of my Velodyne DLS5000R recently. Probably a transformer or a capacitor in the power supply. Maybe the architecture of your amplifier is open and you can find it easily, but on mine, it's closed and glued where I can't get to it, and the only solution from Velodyne is to send it back for a replacement, at a flat charge of $230. Frustrating!

I get static thought my speakers they are hooked up though an amp im also running another amp thts running the sub i was seeing if u guys can help me fix the static noise

check all connections (speaker wires and rca jacks for shorts) replace them one at a time and listen if the static continues. Sometimes the static is due to a broken solder joint inside the amp either on the input or output connection post. hope this helps

The fade button isnt turning on the speakers in the bakc of the wagon. we just bought the car but have no owners manual. front speakers are good

They could be unhooked. If they were hooked up but blown, you would here static. If you hear nothing theyre either unhooked or the radio console is messed up.

The powered subwoofer should be connected to the black subwoofer output near the bottom of the receiver in just about the center. A subwoofer uses line level signals and has its own amplifier, Good chance that you wiped out a channel. Put the wiring back the way it was, and IF the channel was not directly connected to the speaker terminals, MAYBE, JUST MAYBE it will still work.
Chances are slim...

Check your rca cables they might be loose or not connected to the amp or the radio. Sometimes those rca cable outlets get worn out by being bumped, moved, hooking up and pulling out connectors. Plug in your rca cords and wiggle them on the amp while radio is on and see if the music cuts in and out

Voice coil has been blown open. Most likely alot of times what I do to test a speaker is connect it to a 9 volt battery. on and off and the speaker should bounce. If not speaker is blown. Plus this way you could save yourself lots of problems. If the speaker was shorted and not blown open. You would now possible have a blown amp and home stereo.
