SOURCE: Subwoofer Connection: Speaker wire to Mono RCA

The easiest solution to use your subwoofer is to buy an amp for it. Any old stereo receiver from a garage sale will probably do just fine.

  1. Connect the mono RCA subwoofer output from your Sony with a 1xRCA-to-2xRCA splitter to both the left and right input of the cheap reciever's tape or aux input
  2. connect both speaker outputs of the cheap reciever to the speaker input on your subwoofer. make sure both black (-) outputs on the reciever connect to the black input on the sub, and the red outputs (+) on the reciever are both connected to the red input on the subwoofer.
  3. make sure the cheap receiver's volume is all the way down. turn your Sony up to about the loudest you'll listen to it. turn up the subwoofer amp until it's loud enough to sound good.
  4. leave the subwoofer amp alone, the Sony volume will all you ever need to touch from now on.

You can even now turn off your subwoofer / adjust the volume easily now!

SOURCE: I HAVE JVC SURROUND SOUND

Here is a link to the system cable that I think that you are reffering to. The model number of the system you have is TH-M45

The model number you gave is for the sub-woofer only. This is the system cable that is required to connected between the sub-woofer and the main head unit with the DVD changer in it.

If you can not click on the above link, just copy the entire link and paste it into the address bar of your interent browser.

Since this is the part you want and it is the cheapest place to purchase it, a rating of "FixYa!" would be appropriate and very much appreciated. After all, it is the only reward we get for offering people like yourself this free technical support.

SOURCE: Bose Acoustimass 15 woofer, Replacement of RCA female connector

On the end opposite of the jacks (top of the sub opposite connectors) in the exact middle, there is a ratchet looking device (flashlight and magnifying glass reveal the little culprit) with a very small flat screw driver rotate the piece CCW until a small tab is protruding from the middle. Pu the palm of your hand on the plastic case and give it a small whack (in the direction of the jacks) it will move about a 1.2 inch. Lift straight up and the case will come off and reveal the connectors. Trust me, get a flashlight and magnifying glass and peer through the small crack between the cover and the box, you will see the little notch (encoder looking) rotating wheel

SOURCE: My amplifier has one pair of rca inputs. radio only has 1 output

Subwoofer signals should be MONO - not stereo (hence the single Component out on the radio)
Only use one RCA to send signal to your amplifier.

If you use a Y splitter - the signal voltage will be cut in half - deteriorating the quality, and therefore amplifying "dirty" signal.

If you require further help, simply reply to this thread.

Thanks for using FixYa - a FixYa rating is appreciated for answering your Question.

Subwoofer not working


The subwoofer is normally the main power supply for the other speakers. When setting up the system, there is a set up guide which allows you to control the power supplied to each speaker. You may have inadvertently set the subwoofer to have 0 output.

Can i hard wire my rt 2770 rca home theater subwoofer to my receiver lost white plug that plugs into receiver and can't find a new one?


I have one if you still need it. Hooked my sub up to a different receiver and cut that end off to hard wire it. It has about a foot of wire and the white plug on the end that goes into the receiver.

I have an rt2870 and am just wondering where i connect the yellow subwoofer cord to the TV at, and i set my tv setting for the surround sound


You shouldn't connect the subwoofer to the TV. Just connect the Right and Left audio cables (red and white RCA plugs) to the TV audio out and then the other side goes receiver's audio in. If you are using the subwoofer that came with the unit, connect it to the sub port (purple and grey or black striped). The red and black striped cable goes to the subwoofer control.

If you are using another active subwoofer, connect it to the RCA jack labeled Subwoofer Audio OUT.

If you have a 3-plug RCA cable that is a composite video cable. The yellow plug carries the video, the red and white carry the audio signal. This cable is most often used for connecting older VCRs and game systems to a TV (or newer devices to an older TV). Thus leave the yellow jack dangling if using it for an audio cable.

Set your TV to use the external audio speakers and the receiver will take care of the signal to the subwoofer. (You only would connect the speakers individually for a computer sound system.)

I hope this helps.

I have a subwoofer with standard speaker wire connection, how to I attach to a receiver with a subwoofer cable?


The Subwoofer is Likely Passive....meaning no amplifier is within the enclosure itself....the incompatible connectors mean you cannot connect the subwoofer itself to your surround sound system.

look for a Suitable stand-alone (1 Channel) Amplifer with sufficent power.....connect the RCA Imputs (subwoofer cable) to the Recievers RCA subwoofer output....then connect the amplifier's output to the the wire going into the subwoofer enclosure....if there is a plastic connector simply cut it off and strip the wires down a sufficent lenght....then secure the wires to the output of the amplifier.

if you do this make sure you know the ohm rating of the subwoofer and the minimum ohm rating of the amplifier your using.

I need the audio cable that hooks the dvd/vcr player to the subwoofer


your player output is RCA connection and your subwoofer since you didn't mention it i think its a mini jack connector or BB plug connector...so you have to costumize for that cable... or u will buy a RCA cable in the market then buy a coonector that will convert your BB plug in your subwoofer to RCA... i

what i mean is this... from your player put a RCA coonecotr it is 2 wires in your subwoofer its output is BB plug so you have to buy a connector that will make your BB plug become a RCA male...in your RCA cable from your player its output is RCA male so again convert it to RCA female connector to so that you can connect it

COBY cs-p63 ,how to connect to a computer


Hello,

with this system it comes with connector cables, on one end is 3.5mm to go into your computer and the other end is rca jacks that go into the subwoofer, all the speakers go to the subwoofer. your computer must have all 5 ports to get true surround sound, if not, just hookup the ones for the FL FR and run RCA split from that to the speaker output on your computer.
