I wish to replace a subwoofer on a surround sound system


In most surround sound systems the sub woofer is powered separately and uses a standard RCA coax connection to the receiver/amplifier.

Replacing is simply plugging in the new and reconnecting the coax cable.

Usually the audio signal is Dolby Digital 5.1 the (.1) is the LFE Sub-woofer. The connection is between the Subwoofer RCA connector on the amplifier and connects to the (LFE-Line) in on the subwoofer speaker.

Hope this helps?

Can't get cable sound to run through surround sound


You would have to have a cable box, from the cable box, you would hook up the yellow to your tv, and then the red/white audio would go to the subwoofer on your DVD765 where it is labeled (TV), you then hit the switch on the subwoofer to TV. Another option is if your TV has audio output, you could just run RED/WHITE audio from your tv to the back of the subwoofer where it is labeled (TV).

We have a jvc home theater surround sound system and the subwoofer just stopped working. the model number for the sub is sp-pwc30 and we want to just replace the subwoofer any ideas how to get one?


Depending of the type of Subwoofer that required your system.

A) Amplified Subwoofer. (With 110volts A.C. cord attached to the sub)
The subwoofer electronics circuit needs repair or change.
You will find a compatible subwoofer for this type of subwoofer in audio appliance stores.

B)Not amplified Subwoofer (No 110volts A.C. cord attached to the sub)

Bring your sound system to a technician to have the soldering remaked to the devices bolted on the main heatsink.
And have the Subwoofer checked too.

This type of subwoofer can mostly be buy in kit with the satellites speakers.
And need to match thee impedance of the output of your system.

Search for ( 4 ohm or 6 ohm 8 ohm ) near the Sub outlet behind your system.

Have you tried connecting an AV cable from yoursuboofer to your TV?
If so, what type of connection cable does your Woofer have?

Is your subwoofer apart of a surround sound system or is a separate unit?

Subwoofer FPS 1000 4.1 sound bad


hello,

I had a problem closely with my FPS 1000 4.1 sound works four point surrond : my subwoofer sounds a metallic noise when the bass are loud.
Maybe it is the same problem ? :

It were vibrations that go through the subwoofer and cause the noise.

Check the four screw well (the four hole on the back of the subwoofer). Put your finger on them to clog them and hear if your problem is solved.
If yes, put scotch on them.

Secondly (i think you have disassemble your subwoofer), you can put silicon joincture on the box near the circuit, under the translucides cables. (the box where there are the plugs). >> if there are any hole between his box and the speaker, there will be some metallic noise (vibrations trough the box and the back plugs).



bye

Subwoofer humming/buzzing


It sounds like one of the internal solder welds to the cable or a/v connections inside the cable box is bad.

Acoustimass Subwoofer has a low "hummm" sound when turned on.


Sounds like an inadequate ground wire in the signal cable. You may have to replace the cable between the reciever and bass module. It also, however, may be IN the bass or reciever module.
