If it doesn't show a diagram by the speaker terminals you probably can't/shouldn't with your amp. Usually they show attaching the positive of one channel and the negative to the other to the speaker. If it doesn't show you how or say Bridgable on the amp - I WOULD NOT TRY IT.

Very week sound


Definitely need more info - such as type of amplifier or receiver, how many speakers you are running, whether the subwoofer is powered or not.
As a simple test procedure: Disconnect all speakers and plug in a pair of headphones. Get a strong audio signal? Good, move on. No signal or week signal, you have an amplifier issue before the audio even gets to the speakers.
Next: Disconnect all speakers, turn the volume down, and connect one speaker to the left output channel. Slowly increase the volume. If that works, do the same on the right channel. Everything OK? You're putting out enough gain on both channels. Sometimes one channel goes bad. You can still listen to your sound in mono moder, or drive two speakers from the single working output. Not stereo, but dual mono. Move on.
Connect left and right speakers but not the subwoofer. Repeat the test. Whatever is left is probably the problem. If the subwoofer is powered, check the power supply or incoming voltage. If the other speakers are driven off the subwoofer or powered from there, that's likely the problem.

Im trying to hook up a paradigm pdr-12 to my tv and xbox 360 and need an idea of how to do this the right way so it only plays the bass and nothing else


Hello there this subwoofer has a built in crossover variable from 50hz to 150hz which means that any signal you feed it the sub it will ignore anything but bass anyway.

As for the connection it is made quite difficult if you don't already have an amplifier powering your other speakers, usually home cinema amplifiers have a low level pre out for subwoofers, for which you would just need a phono to phono cable.

However if it doesn't and you have any type of amplifier with at least 2 separate left and right speakers you can connect the wires from these into the subwoofer and it will output the bass from these 2 channels.

Another option is to use a mono to stereo (2 to 1) phono cable where the 2 connectors at one end connect to a tape or record output on your amplifier and the single phono at the other connects to the subwoofer, the same would go if you have a red & white phono (RCA) output on your TV you could also use this to power the sub, in the worst case scenario you could use a single to single phono or rca cable to connect one of the output channels (left or right) on your TV to the subwoofer however this would mean that the subwoofer would only output bass from either the left or right channel.


Hope this helps


Kind Regards

Conncet a sony sub to a denon reciver


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..

Hello, can someone help me, i want to know how to connect the wires if i want to use 2 channel instead of 4. THANKS IN ADVANCE!!!!!!!!!!!!!


You would want to bridge 2 of the left channels and 2 of the right channels, essentially combining the power output of the amp.

This article should help you out:
http://knowledge.sonicelectronix.com/car-audio-and-video/car-amplifiers/how-to-bridge-an-amplifier.html

Essentially you will just be using 2 channels (left, right) instead of 4 (front left, front right, rear left, rear right) essentially combining the power of those outputs. You'll want to check the amp to see if it tells you which of the outputs should be used for the "bridged" method.

Best amplifier for bose 901 VI speakers


By all-in-one amplifier that handles the surround I think you mean all-in-one receiver or preamp. Amps are just big dumb muscular power supplies for speakers.

The source control and digital decoding could be handled by a modern AV receiver with multichannel analog outputs for driving separate amps or you could get a digital AV preamplifier/control unit functionally like this Adcom. Prepare for sticker shock.

http://hdtvdreams.com/Adcom-GTP-870HD-7.1-Multi-Channel-Processor/Preamplifier-GTP870HD.aspx

Understand that EACH PAIR of Bose 901's will require its own DEDICATED two channels of amplification AND someplace to jack in its Active Equalizer - between the line level source and the power amp.

Conventional speakers can probably run off the receiver's amplifiers since they don't/can't/must not have the Bose Active EQ in line with them.

Having a single pair of 901's plus a passive subwoofer or two in the same room for accurate 6- or 7.1 surround would require at least four stereo amps or some combination that adds up to 8 channels.

In my own system I have a Pioneer VSX-36TX Receiver (with 5 potential channels of amplification for Left, Right, Center, two Surrounds) doing light duty as the control and routing center but ONLY driving the Center (two Kenwood 777's) and Surround speakers (Bose 301's). I have a Carver 5-channel amp pushing the Bose 901 Front speakers (100Wx2), two dbx Subwoofers (110Wx1) and the Bose 301 Rear Surround speakers (60Wx1).

You could probably get by with a powerful 2-, 3- or 4-channel amplifier to push the 901's and subwoofer(s) as I did. It's the cheapest way out if you get a decent AV receiver. Once you set up the levels and delays the receiver does all the thinking and controlling for you.

if you have dual voice coils connect on each seporate sub negative left channel to possative right channel of the subwoofer same to other sub then conect the left possative and the right neggative to your box power terminal same to other sub then conect the two sub outs on your box left speaker positive to your positive left channel bridge then conect left speaker negative to the right speaker possative then connect your right speaker negative to your right channel negative brigdeg to your amp is single coil hook the box its self up the same way to your amp i have two dual voice cooil 12" hooked up to the same amp that way and it rocks without the power protecter turning on

Subwoofers


This will depend on the amplifiers capabilities.

I will give 2 different scenarios.

#1 Stereo configuration

If the amplifier supports an RMS power output close to the RMS input power of the subwoofers then run the amplifier in stereo mode. For example 150 watts RMS X 4 channels driven at 20-20khz. (If you can provide a model # for the subs and the amp your looking at I can help you further with this decision.

Wiring for this is easy and simply involves matching the connectors for 2 of the channels (Front or Rear) to each of the subwoofers.

#2 Mono Bridged mode.

If the amplifier is lower power but mono bridgable you can bridge two Pairs of channels and power each of the subwoofers this way.

Generally speaking a 2 channel bridgable amplifier will be able to at least combine the wattage of each channel into a single monural channel and in many cases its actually higher.

So you would bridge the front 2 channels into a single bridged mode for one subwoofer. and then you could bridge the read 2 channels into another bridged mono channel for your other sub woofer.

For example if you had bridgable amplifier thats 50 watts RMS X 4 you coudl very likely (Generalization based on quality of amplifier) send 150 watts RMS to each subwoofer.

Again I would need to know what amp you're refering to to provide specific wiring instructions. Many Bridging amplifiers either have a single switch that will send them to bridged mode or you would use the positive + terminal from one channel and the negative - terminal from the other channel or a combination of both.

RCA cable use


You can plug into the left channel and it will feed both the left and right channels.

To confirm that it's feeding both channels, connect the speaker to one channel at a time. With signal fed into the left channel only, you should get sound when you connect the speaker to either channel.
