Good chance it's the power supply; a capacitor there, the large one, may have gone. These things age and when they go, there's noisy power to the amp circuit and ... well, that may be what you're hearing. You should check your audio wiring, too. That woofer could be picking up a 60Hz hum from the AC mains and amplifying it. Maybe you can try another spkr on same cables and see if hum is in your woofer or elsewhere. Good luck.

If you have checked the fuses which it sounds like you have, your amp may be out. Take that RCA and plug it into the other speaker. If thar she blows, treat as warranty and call the factory. If this is helpful, please post as such.

It sounds like the voice coil is blown. You could price just buying a replacement sub for it or pricing a whole new unit

SOURCE: JBL PB10 subwoofer sounds distorted and lights on the front flash

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.

Bose 321 power woofer buzzes but produces no audio sound


I assume the other two speakers are working fine. Contact Bose and ask them. Could be a simple fuse. Sounds like a fried speaker driver, but do this first. Take the back off and check the power amplifier for a blown fuse. If none, disconnect the power amplifier. Reconnect the speaker cabinet w/o the built-in power amplifier to a known good amplifier to see if the speaker works. If it works then you know its the built-in power amp that's fried. Contact Bose for a replacement or better yet buy a another one with a higher RMS watt capacity. Wattage ratings in other than RMS are worthless. JBL and Cerwin Vega produce high wattage units. You need to keep the volume lower to avoid the problem in the future.

Can we use the subwoofer as an amplifier for speakers? it has jacks for speaker in/out, but i can't figure out how to make it work because the speakers have no sound.


I don't believe this hookup is amplified; but, if you have used the regular unfiltered speaker connections from your receiver/amplifier to hookup the subwoofer, the system will pass the signal thru the outputs subject to the crossover adjustment on the back panel. You cannot get the full signal if your system is sending only the bass signal to the subwoofer. I have copied the instructions below from the manual. You would set the high freq crossover to the low end of your satellite's frequency range. The full manual is here: http://www.jbl.com/EN-US/Products/Pages/ProductSupportDetails.aspx?PID=PSW-D110

High-Pass Control
• If you hooked up your subwoofer
as shown in Hookup
3 on page 4, you also have
the capability of adjusting
the high-pass frequency.
The High-Pass control
determines the frequency at
which the main speakers
will start reproducing
sounds. If your main speakers
can comfortably reproduce
some low-frequency
sounds, also set this control
to a lower frequency
setting, between 50Hz –
100Hz. This will concentrate
the subwoofer’s
efforts to the ultradeep
bass sounds, while your
main speakers continue to
reproduce the mid-bass
information. If you are
using smaller bookshelf
speakers that do not extend
to the lower bass frequencies,
set the high-pass crossover
control to a higher setting,
between 125Hz – 180Hz.
With this setting, your main
speakers will not have the
burden of reproducing any
low-frequency sounds.
• If you hooked up your subwoofer
as shown in Hookup
1 on page 3, the high-pass
frequency is fixed at 180Hz.
• If you hooked up your subwoofer
as shown in Hookup
2 on page 4, there is no
high-pass control. Unless
your receiver/amplifier
incorporates a high-pass
crossover, your main speakers
will continue to get a
full-range signal.
Final adjustment and blending
of the low-pass and high-pass
controls may evolve over several
listening sessions. A good
starting point would be to set
both the low- and high-pass
controls to the same frequency
and adjust from that point.

Velodyne model spl88v will only make a high pitch chirp used to only happen at turn on now wont play


Could be one of two things.

The speaker could have a rubbing voice coil, that was the "chirp" sound

Over time, this will damage the speaker. If it shorted, then it may have blown a fuse in the amplifier section.

Any good electronics shop should be able to fix this for a reasonable cost. You also could try the place you purchased the unit from.

You could also contact Velodyne.

High pitched noise comin from sub


if sound also goes away when throttle is released and sound returns when throttle is pressed down, then you have engine noise from car engine electronics. In older cars, this was quite noticeable when the cars had distributor caps. The electrical noise caused by arcing required for the spark plugs could be your issue. It is resolved with a noise filter which gets wired inline leading to your in-dash deck and power amp (if you have one). The filter can be found many places including Radio Shack and Crutchfield.com. First find your total wattage draw for each component of the sound system (deck and amplifier), then divide by 12 to get current draw through filter. Purchase that size filter or larger.
