Left speaker jack on subwoofer damaged - Harman Kardon HK595 Computer Speakers

Left jack goes to Mic and right jack goes to PC Audio/Headphones.

Depending on the model, there are two ways to connect a subwoofer to an amplifier, receiver or processor. The best way is to connect the subwoofer to the SUB OUT or LFE output of a receiver, but some subwoofers can be connected to the speaker level outputs of the receiver or amplifier.


1. How to Connect a Subwoofer to the Subwoofer Output


The preferred method of connecting a subwoofer is through the LFE or Subwoofer output (SUB OUT) of a receiver. Almost all home theater receivers (or processors) and some stereo receivers have a subwoofer output. The LFE (Low Frequency Effects) is a special output for subwoofers and is often labeled 'SUBWOOFER' not LFE. 5.1 channel programs on DVD discs have a dedicated .1 channel output with bass-only content that is best reproduced by a subwoofer. Connect the output of the LFE or Subwoofer jack to the Line In jacks of the subwoofer using a single RCA cable (the two jacks on the left in the photo). A 'Y-Cable' may be necessary to connect the LFE output to both the left and right channels of the subwoofer.

2. How to Connect a Subwoofer to Speaker Level Outputs
Some receivers and amplifiers do not have an LFE or Subwoofer output. In this case you can use the speaker outputs of the receiver to connect the subwoofer. Using speaker wire, connect the left and right channel speaker outputs of the receiver to the left and right channel speaker level inputs on the subwoofer (the speaker inputs on the right side of the photo). Using speaker wire, connect the left and right channel speaker outputs on the back of the subwoofer to the left and right channel front speakers.

Hope it helped..

Assuming you have the BA745 2.1 speaker set up, all of the cables connect to the subwoofer and then to the computer or the satellite speakers (these are built into the speakers IIRC). Take the cable with the black box (2 pins) to red and green. The red and green plugs go into the matching color ports on the computer and the pins on the black end fit into the jacks between the those for the two satellites. Plug the single end speaker cable into the subwoofer port all the way to the right on the back of the subwoofer. Plug the wire with the two plugs into the matching color jacks (blue to the left, red to the right). Then plug in the power adapter cable in the farthest left jack and plug in the other end to a surge protected power strip (that is plugged in and turned on).

No, Please do not try that it is not the right approach and it can also damage you DVD player.

Step 1 Connect the green connector
from the subwoofer into the green jack on the computer
(the black connector is not used)

Step 2 Plug the orange connector from the right/control satellite into the orange jack on the subwoofer.
Step 3 Plug the brown connector from the left satellite into the brown jack on the subwoofer.
Step 4 Plug the AC plug into the wall outlet.
Step 5 Turn on the speaker set and adjust the volume accordingly.

Sort of sounds like there's a PC in the mix.

Can you swap the left and right speakers to isolate the speaker from the source as the problem?

Have you tried switching the various plugs around to isolate if anything comes out to the Left Channel, ever or if any other speaker plugged in as the Left works at all? Turn the volume down and bring it up slowly at first because if you send Subwoofer programming to a speaker not designed for it you may damage it.

If nothing works when plugged in as the Left speaker, maybe the sound card is the problem. Resubmit a question with the source or the PC as the problem

On the back of the amp, there should be a jack with the name "SUBWOOFER PRE OUT". It is a standard RCA jack, but it only puts out a line output, meaning only self-powered subwoofers will work with it. Usually, if the subwoofer does not have an amp, it will have 2 imputs and 2 outputs. You plug the two left and right inputs into the front speaker jack on the amp, and then plug the front speakers into the left and right amp on the subwoofer.

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.

Please check your model number, I can not find it on the JVC service website.

This is a powered sub-woofer I think. You need to have a thick black cord that connects the sub to the head unit. Then the satellite speakers get connected to the speaker jacks on the sub-woofer box. The sub-woofer should also be plugged into an A/C outlet on the wall.

The speaker outputs are labeled right there where you connect the speaker wires. You should see a red and black connector for each speaker and they are labeled "front right" "front left" "center" "rear right" "rear left".

If you do not have the thick black cord you need to connect the head unit with the sub-woofer, you can not use this system.

If you look at the head unit and give me the model number on it, I may be able to find the part you need. But I must have a good model number to work with, preferably from the head unit.

have you checked for the continuity of the wirings? check for the resistance of your speaker from it jack..... it should measure close to 8ohms or 4ohms using a digital multimeter (DMM). check also the sub out jack of your reciever if there is a signal from it using your main speakers if they come with jacks also (turn the volume low to prevent damage to other speakers you connect on it!
