Try spraying switch cleaner into the body of the volume control. Sometimes works but if the resist is worn then the only solution is to replace the component.

No sub woofer output or very little


Your sub amplifier is detecting an overdrive condition and reducing volume to prevent the output stage from burning up. When reduced volume doesn't work, output is cut completely for 10 minutes until things have cooled down.

Tip for your home theater system: tweak your subwoofer level and crossover...


An important tip regarding your home theater system is to Tweak subwoofer-level and crossover controls:
Test tones and meters aren't the final arbiters in the bass department. If your sub's bass is boomy, thick, or uneven, first try lowering its volume --most people complain that their sub louder than necessary. Next, if your satellites are very small, the crossover control should also be set to its midpoint or higher. Bigger speakers produce more bass on their own, so they sound best with the sub's crossover knob set at or near the bottom of its range. Finally, moving the sub out of the corner and closer to one of the front speakers may produce smoother, flatter bass.

Subwoofer makes noise like an untuned TV regardless of volume knob


I would suggest your crossover unit has failed in the speaker cabinet. The crossover circuit board separates the low and high frequency content of your stereos audio signal. The low frequencies go to the bass unit (woofer) and the high frequencies go to the tweeter speaker. If the capacitor on the crossover goes open or near open circuit then noise is introduced into the sound system. Replace either the capacitor or crossover unit.

A425 subwoofer, more bass? wires came off, no bass managment.


I wouldn't cross wires or leave one disconnected. Can you solder the wires back on the the control knob? Did you feel the subwoofer cone to see if it's working at all? I would guess the wire you didn't connect, is the subwoofer wire. Try putting it back to original cofiguration and solder the wires in place.

Can i put an extra sub woofer on my lg da3525 via the woofer out socket and what plug do i require to do this


Hi,

How to Connect 2 Subwoofers to One Receiver

Subwoofers produce the deep bass sounds that give home theater the realism of being at the movies. A good subwoofer can rattle the walls during action sequences, while adding depth to recorded music and a heightened sense of feeling in the midst of a televised sporting event. Because most home theater receivers are equipped with a single subwoofer jack, connecting a second subwoofer requires a simple audio adapter available at electronics stores. Self-powered subwoofers have their own built-in amplifiers to drive the bass speakers, so they cannot drain power on the main receiver in a system and thus pose no danger to the equipment, even when an extra subwoofer is connected.

Things You'll Need:

Home theater receiver
Y-adapter with RCA jacks on two ends and an RCA plug on the other, available at electronics stores.
2 RCA subwoofer cables
2 subwoofers


Instructions


Plug the Y-adapter into the home theater receiver's "Subwoofer OUT" jack.


Connect an RCA subwoofer cable to each jack on the Y adapter and route the cables to the subwoofers in the room. Because subwoofers deliver an omnidirectional sound, the boxes can be placed anywhere they won't get in the way, but within reach of an electrical outlet..


Plug an RCA cable into the "Sub IN" jack on the back of each subwoofer.


Connect the subwoofers to wall outlets and turn on each unit by pressing the power button, typically located on the back panel.


Adjust the volume and crossover settings on each subwoofer as desired. The crossover adjustment knob tells the subwppfer which low-end frequencies to reproduce from the audio signal, such as a movie on DVD. All frequencies higher than the crossover setting will be transferred to the other speakers connected to the receiver.



Tips & Warnings

Use subwoofers that are closely matched in power, as rated in watts, when using two subwoofers in a home theater setup.

Disconnect the subwoofers from the power supply while making the audio connections.


Have a nice day...

Bass goes off when i turn up the volume


You need to install a heavier gauge wire to your amp and a capacitor. It works fine at low volumes because there is enough wattage from the battery to power the bass output of the amp but at higher volumes the amp does not have enough power.

Heavier gauge wire supplies more poer, and a capacitor stores a reserve of wattage for the amp to use so that it does not run out while blasting your tunes.

5.1 surround sound


Here is how you fix it. Its really easy actually take a look at your Subwoofer 99% of the time you can control two controls for your bass somewhere around the Subwoofer. If you raise the volume of your Subwoofer you'll get more bass. Try it and let me know how this works out for you alright.

Troubleshooting on Adjusting Treble/Bass


Look in your owners manual and make sure you are turning the right knobs or pushing the right buttons once you have the adjustment screen for the bass/treble showing. It could be that they use different knobs/buttons than the volume control. If you are using the right controls, then you have a problem that only a shop can fix. You might reset by taking away all the power (acc and bu) for a couple minutes and then reconnect, but if that doesn't help then it time to go to the shop.
