I was trying to find an owner's manual or picture of the rear panel of the sub, but had no luck. The subwoofer is a powered type - or "active" speaker. This means it has a built in amplifier. These active subs usually provide for one or both "low level" and "high level" inputs. Low level signals are usually carried by shielded coaxial cables and have RCA type plugs on the end. The low level is also called "line level". This is an un-amplified signal that might be heard on cheap earphones - but that's about it. It is similar to the output of a tape deck, DVD or phonograph. These signals require an amplifier to be heard. If you have a sub woofer output on your receiver or amplifier, you could run a patch cable between the low level input on the subwoofer and the subwoofer output of the amp or receiver. You receiver or amp may call this output "low frequency effects" or similar. The front and rear speakers would then connect directly to the receiver or amp's corresponding connections.

If you lack low level outputs on the amp or subwoofer, you'll need to run speaker wires from the amplifier or receiver's front left and right speaker output terminals to the subwoofer's high level input terminals. High level signals are speaker connections or amplified signals. These are typically connections that accept bare wire connections. The front speakers would then connect to the subwoofer's front left and right speaker output terminals. The rear speakers connect to the amplifier.

I hope this helps - and good luck!

This sounds like a dry capacitor on the input / output audio circuit or a dry solder joint on the IC chip left output.

audio board located inside the mainboard console to the right trace your speakers wire to bd, disconnect the three leads, 3 phillips screws, and examine bd for burns. If yes, ebay the board id for a replacement.

Hi, as a retired installer maybe i can suggest a better configuration. I would run your front speakers in series with your rear mids in low level. Your sound will be alot cleaner. Hppe that helps.

AUX usually refers to an INPUT, such as a CD player, etc. No signal comes out of a standard AUX jack, unless it specifically says "Aux speaker output". Instead, look for another speaker output jack, such as remote speaker, B speakers, etc. You may only have one set of speaker output jacks, in which case you would need to connect your wireless speaker to the speaker output jacks along with your main speakers, or buy a little speaker selector switch box to switch between main and wireless speakers. There's usually no harm in connecting more than one speaker set to the same outputs, though it is technically not recommended. In the real world, just don't crank it too loud and you'll be fine. The wireless speaker MIGHT run off of a standard line output also, if the wireless speaker has its own power amplifier.

you have to go to your audio output setup (try to look for an audio-related icon on your taskbar - next to time display)
setup your audio output for 6 channel or 5.1channel output (depending on software)
follow on-screen description of where to plug in your speaker jacks - green, peach and black.
enjoy...

1ST.-The right jack could be damaged!!
Usually, there is a [+} posaitve & [-] negative input\output to speaker connections. Not all [-]neg. is ground.Sometimes the [+] pos. is grounded. [The exception to the rule is that u SEE the black wire going to ground] the reason I am letting u know this is that u can test the INSIDES of the sound system.
If u can get inside of the unit. Cut the left speaker output [+] posative from both outputs. criss\cross wires.Place left speaker output to right speaker jack[ that does not work!!] & visa versa.If the [LEFT Output] stops working after u plug in the speakers,the internal RIGHT output is damaged. NEEDS TO BE TESTED
If nothing nothing changes.The left still works & the right still does not work, then it is the jack (shorted ?, opened internally ?)
