Hard to tell whats causing this .Just curious make sure speaker wires going to subs are POLARIZED meaning positive from amp is with positive at woofer and NEGATIVE is with negative at woofer.When these are crossed and when volume is raised you will hear the bass cancell each other out..

    ohh okay ..thats better info than your previous..check the ground wire to amp .make sure its not on top of paint from car.make sure ground is to solid metal .Also you could adjust the gain properly to amp .first adj amp gain setting to lowest.then turn radio volume as high as it can get without distorting sound .Then touch it down a pinch .Then go to amp and raise amp gain up until amp cuts out .Then touch down a pinch .then your amp and radio are gian adjusted...

My subwoofer cuts out when their is only talking and there isnt any music or bassy stuff and stays off, once the music and anything that has bass starts up then it will come back on maybe its a setting...


You don't mention the sub model. Many have a setting for automatic response in the presence of a signal. You could try teh alternative to auto, maybe Always On.

Unable to receive optimum output. The bass is totally flat !


Hi, ok the Bose Acoustimass III system consists of two small cube speakers and one subwoofer unit called the Acoustimass bass module. If the subwoofer stops working, three points can be the cause of the failure. The Bose Acoustimass III is a passive system, meaning the speakers do not power themselves, but instead are connected to a receiver or amplifier. Thus, the amplifier, the speaker between the amplifier and the subwoofer, or the subwoofer itself could be the issue.

Things You'll Need:

* Amplifier
* Speaker cable
* Extra subwoofer


Instructions


Disconnect the speaker cable from the back of the Bose Accoustimass bass module and connect it to a subwoofer that is known to be working. If the subwoofer works, the bass module needs to be replaced.


Disconnect the speaker cable from the back of the receiver or amplifier you are using and from the back of the subwoofer in Step 1.


Connect a speaker cable that is known to be working between the back of the receiver or amplifier and the back of the Accoustimass module. If the module starts working, then the cable was the issue.


Disconnect the speaker cable from Step 3 from the back of the amplifier or receiver, then connect the cable to the subwoofer port on the back of an amplifier or receiver that is known to be working. If the subwoofer works, the receiver was the issue. If the subwoofer still does not work, verify that the speaker cable is in the subwoofer port of the receiver/amplifier and that the cable is connected securely to the subwoofer.



If you think you did the connection properly,Fine... If not you can use the manual from the below link and know how to connect it properly..

It comes on but no base sound and wont turn up


You have to fill in the details about what you're feeding it (the source and how IT's set up). It won't just >>create<< bass.

From the manual:

If you used the high-level (speaker) inputs and there
is no sound from any of the speakers:
• Check that receiver/amplifier is on and a source is playing.
• Check that powered subwoofer is plugged into an active electrical outlet and is switched on.
• Check all wires and connections between
receiver/amplifier and speakers. Make sure all wires
are connected. Make sure none of the speaker wires are
frayed, cut or punctured.
• Review proper operation of your receiver/amplifier.

If there is low (or no) bass output:
• Make sure the connections to the left and right “Speaker
Inputs” have the correct polarity (+ and –).
• Make sure that the subwoofer is plugged into an active electrical outlet and switched on.
• Adjust the crossover point.
• Flip the Phase Control switch to the opposite position.
• If you are using a Dolby Digital/DTS receiver or processor, make sure that the subwoofer adjustments on the receiver/processor are set up correctly.
• Slowly turn the Level Control clockwise until you begin to hear the desired amount of bass.

If you used the line-level inputs and there is no sound
from the subwoofer:
• Check that receiver/amplifier is on and a source is playing.
• Check that powered subwoofer is plugged into an active electrical outlet and is switched on.
• Check all wires and connections between receiver/amplifier and subwoofer. Make sure all wires are connected. Make sure none
of the wires are frayed, cut or punctured.
• Review proper operation of your receiver/amplifier.
• Slowly turn the Level Control clockwise until you begin to hear the desired amount of bass.
• Make sure that you have configured your receiver/processor so that the subwoofer/LFE output is on.

Subwoofer wont work


Receivers often have the ability to switch off the subwoofer channel. Especial if it wasn't connected before. If it has the ability to do a speaker test or set up try that. If it bypasses the subwoofer that will confirm the channel is not on.

Hi bob,
yes I have the active subwoofer book, SA-W305 1998

If you let me have an e-mail address, I will scan and send you copies (8 pages) regards Brian.

P.S. I have been using the unit on its own, just connected to my new tv, and the bass improvment is fantastic.

I had to have the amp TA-VE150 repaired,by having the IC joints resoldered, due to overheating.

Hi Cassie, unless your receiver is a surround reciever, it won't have an actual subwoofer output. The good news is that you can use either a "line out" jack or a "tape out" jack instead, which most receivers do have. These jacks always have the signal, so there are no special settings to remember - simply operate your receiver as usual. Everything comes out of these jacks, not just the bass - but it won't matter since your subwoofer will only reproduce the bass frequencies. The bass information is generally identical in both left and right channels, so either the right or left jack should work fine, and it's okay to leave the other one unconnected. The only bad thing is the line and tape outputs are not affected by the receiver's bass and treble controls, so you'll have to control the bass volume at the subwoofer if it has a control. If you can't control the amount of bass you hear, turn up the volume and reduce the treble which will give the illusion of more bass. I'm assuming you have "powered" subwoofer (has its own built-in amplifier). Good luck!

Cerwin Vega V-10S Subwoofer doesn´t sounds good


dear "rai17"

This, to me, is most likely the voice coil inside the driver rubbung against the yolk plate, or possibly the spyder slapping the metal plate underneath it, or the amp-(if it has one?) getting tired. this can occur from poor build quality, or playing the subwoofer too loud. depending on how much it cost you, you may want to get it repaired(voice coil re-alignment or something or new amp). But the way it seems, it is probably the driver itself. subwoofers get looser as they break in. This one may have been over-broken....sorry

I hope this helped clarify what is happening!
