This subwoofer is probably powered directly from the amplifier and doesn't have an internal amp. The connections are probably the same type as for any other speakers. And, there are probably additional connections for the rest of the speakers. The connection on your amp is likely an RCA phono plug connector that sends low level signals to a powered subwoofer. To connect a passive subwoofer, one without a built-in amp, the main speaker outputs connect to the subwoofer and are then sent to the regular speakers connected to additional terminals on the subwoofer. You may need an owner's manual for the subwoofer to determine how it should be connected.
Connect the subwoofer the following way if you have a separate subwoofer out in your amplifier (ie. 3 channel amplifier). Ones on the left are -1 and +1, the ones on the right are -2 and +2. I think you have to join +1 to -2 according to this diagram and then join -1 and +2 to the subwoofer out in the amp. I took this diagram from the following website but check with someone else as well.
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.
With everything connected correctly there could be a couple of possible problems:
1. If your receiver has on screen display capabilities, you may need to turn the subwoofer output "on" 2. If your subwoofer has speaker wire inputs/outputs, you could run speaker wire to it, then to your speakers & test if the subwoofer is working... hence verifying that the receiver has a function to turn the subwoofer output on/off 3. The cable between the subwoofer & receiver could be bad. Try another cable.
Good day. I take it that you have two subwoofers to connect and will explain the connections thereof. Place the two subwoofers face down and notice the connection point marked -, + on the one speaker, and the same-,+ on the second speaker. Now connect the center + and - together, leaving the two outer connection points open. The outer connection points will go to your amp. Next, take note on your amp, a "bridge" connection. It should be the outer connections on your amp. Hope this helps
Are these Dual Voicecoil Subwoofers? Are there 4 terminals on each sub for wires?
If they are Dual 4 ohm voicecoil subwoofers
- connect both + on subwoofer 1
- connect both - on subwoofer 2
- connect both + on subwoofer 2
- connect both - on subwoofer 1
This will give you a 2 ohm STEREO load.
To get a 1 ohm MONO load...
now connect only one of the + on EACH sub to the + on the amplifier.
and the - on EACH sub to the - on the amplifier.
You now have a 1 ohm mono load.
If your speakers are 4ohm single voicecoils (one pair of terminals) the lowest impedence possible is 2 ohms.
This is wired in the same fashion. Both + on the subwoofers to the + on the amp, and both - on the subwoofers to the - on the amp.

deppending on the subwoofer, theres all kinds of converters, u can do this, take the subwoofer to a radioshack or call them and ask that u need a wire converter 4 example say rca converted into headphones & they will hook you up, saves alot of money 4 a say 15 to 20 doller item, and ur subwoofer will be blasting like no tomorrow
hope tha helps
