Can u hook it directly to a lg tv tried but sounded really bad


What are your front channel speakers connected to? Or are you just using the TV speakers for that? Most TVs don't have a dedicated subwoofer output and that's a necessary level of pre-amp out to give the subwoofer proper low frequency signals. If you have an amp/receiver then it probably has a subwoofer output.

Klh powered subwoofer model ASW10-120B... when you plug in to power... it makes a loud buzzing/humming noise


I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

No, those are speaker level inputs and the out side is to pass speaker power from your own amp on to any downstream speakers.

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.

The subwoofer just quit working I don't know if i turned something off. I check the various levels and found one that said "sub woofer off/ on and switched it to "on" but it still doesn't work. any...


1) Check your power outet - make sure you have power.
2) Check the cord going to sub-woofer, check power strip if using one, we want to make sure you have power going to the subwoofer.
3) If so check to see if you have a fuse installed in the subwoofer, replace if needed.
4) Make sure your audio wires are attached to subwoofer, inspect audio wire, if it is old wire then replace.
5) Trace your wire back to your system make sure it is connected to the Subwoofer terminal.
6) Check your menu options on your audio system, make sure the subwoofer is enabled.
