The subwoofers still thump when i turn the volume all the way down. and they're not thumping the song it's kind of random thumping. I looked at the amp, the power wire looked like it was slightly pulled out from the amp.I disconnect the wire and reinstalled and the thumping still happens.Any ideas?

Try running a wire from the ground to the shielding of the rca's. if that works you have a bad rca ground. you can either get the amp repaired or solder a wire onto the shield of the rca's.

Intermittent thumping sound from the subwoofer!

Check for it grounding out somewhere or the ground wire isn't grounded well. If all is well it is internal in your amp.

Wont charge properly, music only last 5 minutes or so

Hello there :)

Try to chance the battery and see if it helps or read this site :

The write on the site :
5. I'm sure my THUMP is fully charged, so why doesn't it play music?
  • Make sure the volume is not set too low to hear.
  • Make sure there are song files stored on THUMP. Connect THUMP to your computer and open the folder that shows the contents of the THUMP memory
  • Make sure you have the correct music file formats loaded into the THUMP memory. Currently, THUMP plays MP3, WMA and WAV file formats. No other music file formats are supported at this time.
  • Make sure the WMA music files you are trying to play are not protected by DRM. (See below for more information on DRM.) If the song files are protected by DRM, you need to download the DRM Enabled Utility found at
6. Why can't I get a full six hours of song play time out of THUMP?
  • Many things affect play time, including the volume level, file compression and music file format. Also, lithium ion polymer batteries gradually lose their charge while not in use. These batteries are also susceptible to temperature.
  • Even though they represent the best technology available, lithium ion batteries do not perform best in high heat.
7. Is it best to completely drain the THUMP battery before recharging?
  • It makes no difference. Lithium ion batteries have no "memory effect" like older technologies such as nickel cadmium, so you can charge them at any time - even when they are not fully discharged.
Hope thats helps
If not then try to return here

I bouht my boston pv350 subwoofer from binglee at beresfield a bit over 12 months ago . i have hardly used it and now it wont work . It has power thats all could you please let me know what i can do with...

call customer service and request info on warranty service period. second ; unplug the sub..for 10 minutes and you should hear a thump when plugging it back to the wall socket. check that the volume is turned up-maximum and finally pull the RCA plugs out- then back into the sub. again you should hear a thump. If no thump. and customer service does not assist, it is a job for a audio repair tech.hope you see something during the steps above.

Makes thumping noise without input from receiver

So no wires plugged into it at all? Sounds like a cold solder joint on a board or a bad connection inside the amplifier.

My subwoofers don't perform consistantly. Sometimes they work flawlessly, other times they make a loud thumping that is not coming from the music (but it does interfere with the music). To be more...

Try turning the gain, or output level down on the amp, if that doesnt solve the problem then check the aux wires and the remote wire for shorts...

P110 thump,twich when volume off

that is normal. Just because they get such a boost when amp is first turned on. You can always turn off high pass and turn gain down just a tick

Pb12 makes thumping sound after warming up

Hello there..Thats normal only if your sub volume and the pre amp is turned up..Your amp is the cause of the speaker jump..Turn amp volume sub level down a few and check your wire from sub to amp..If all of that is good is a normal operation for pre amp warm up in sub if level is turn to max..Try unplugging amp freom sub then turn sub on stand alone(just sub outlet plugged in and no wires from base amp plugged in..If sub stops the its the amp making the problem..If it still is there then the pre amp is either dusty on inside or the outlet plug that it is plugged in doesnt have a good ground..Hope these help to solve your problem..Have a great day...

Subwoofer "thumping" w. no audio feed

You need to check your ground connection. If there is a bad ground there will be feedback to the amp and it will just sit there and loop back with the Thump, Thump, Thump sound. I had to wire my amp's ground all the way back to the negative battery terminal. It was a pain but I have never had a problem since :)
