Question about Speakers & Subwoofers

Connect powered subwoofer

My stereo has 1 RCA audio out for the powered subwoofer. The subwoofer has a low level input RCA R (mono) and L. Do I connect the stereo's subwoofer RCA out to one of the Subwoofer RCA input jacks? Or do I hook up all the speaker wire of the Subwoofer for the High Level From Amplifier ''In'' AND High Level ''To Speaker'' Out? And if the answer is to the last 2 questions, where do I hook up those speakers wires on my stereo since I do not have ''Subwoofer'' speaker inputs OUT and IN on my stereo?

    Sounds like you just connect the RCA Sub out to the R (mono.) You may need to enable the sub out put on your amp, though.

  • If your receiver has a dedicated subwoofer line level output, we recommend connecting your subwoofer to this jack. Most receivers will have just one (mono) subwoofer output, while quite a few subs require two inputs. You can use an RCA "Y" adapter cord , which is a cable with one female RCA jack at one end, and two male RCA plugs at the other. Some receivers require menu settings (such as "sub-on" or "front speakers-small") that must be made before the sub output will be active.

    Can I use a JX-S900 Y/C separated I/O to run two subwoofers out of same reciever??


    Yes, on two conditions:

    1) the JX-S900 needs to be a proper matrix switcher. It has to have the ability to route 1 input to more than one output.

    2) the sub signals need to be low level RCA/phono, and not high level speaker wire connections. That's not just about the type of connector. It's about the signal going through those wires. A low level RCA/phono sub connection conducts a maximum 0.7 Volt. A speaker wire connection can transmit 30 Volts! If you put 30 Volts in to a line level switching device such as the JX0S900 you'll fry it.

    Provided that the above two criteriia are both met, then yes it will work.

    • Connect the AV receiver's sub out to Source 1 - white RCA phono.

    • Connect the two subs mono LFE Left input (white RCA) or the single black RCA/phono inputs to the JVC's outputs 1 and 2 - white RCA/phono.

    • Set the source routing: input 1 goes to output 1 and 2

    Infinity Subwoofer input signal mystery


    Have you tried changing the connector leads? They can become faulty. Powered Subwoofers generally work off one connector from the amp. The Sub is a mono amp basaically. So all it needs is the main imput and an earth. One possibilty is that you have the wrong jack plug. Say a stereo instead of a mono, or the wrong size one!

    How do i connect subwoofer (canton movie 125 mx) to amplifier(onkyo txnr609)? there is one subwoofer output on the amplifier with either L & R(mono) high level input or L & R(mono) low level input...


    Connect front the sub out (single) on the amp to one of the rca inputs on the sub, This will work reasonably well but to make the most from the sub buy a 2 rca to 1 rca cable and use it to connect both rca inputs on the sub to the single output on the amp

    Apart from the "line input"


    input and output are for low level ( as with RCA cable connectors) ,, the speaker connections are for high input, (red and black connections. ) you can run the mains to the (rca) from your receiver to run the sub woofers, and from that use the speaker wire connections, to go to the left right speakers, (out only not in) this is done if you want to run the subs and the Rt/lt/ speakers , eliminating the speaker connections coming from the receiver. which you could use for 2 additional speakers if you want

    Hello ! I'm not sure how to connect my kef psw 2500 sub to my yamaha amp. I've got a subwoofer out on my amp but there's 4 inputs on the sub and I don't no which one to use ! Please help as getting...


    Just for clarity, I need to explain what the four inputs are on the KEF subwoofer. There is a left and right RCA input which is the input signal to the subwoofer and there is a left and right RCA output which is the High Pass output from the subwoofer.

    On the back of the Yamaha receiver, you said you have a subwoofer output. This output is most likely the mono subwoofer part of the home theater system and can be used if you like. The left right signal input into the KEF is summed into mono so if you only connect one channel you will basically reduce the signal level by 1/2 (-3dB) but it will work fine.

    Alternatively, if your Yamaha receiver has monitor out and monitor in, you can run the monitor output signals to the subwoofer and you can then run the high pass outputs from the subwoofer back to the monitor in. This will give you the subwoofer and provide a smoother signal matching with your audio system.

    It is not always easy to connect the subwoofer up to an integrated receiver/home cinema system using the high pass channels of the subwoofer as you don't always have access to the analog output and input of the front channels. In this case, just use the Subwoofer output or just the monitor out only.

    I hope this solution is helpful.

    I have a KLH bassbite II sub, not sure how to connect it to my receiver. Can you help? There are 4 wire amp inputs and 4 speaker wire outputs which I am assuming are right and left channels. There are...


    Forget the 4 wire inputs on the sub as you have pointed out. use the low mono input only.this can be plugged into any audio out connections at the amplifier.so it is one rca/low wire from sub to amplifier then plug in power cord and adjust volume as desired.

    My klh subwoofer has R&L connections to speaker and R&L connections to amplifier, but my new amp has a RCA cable connection plug-in. Any way I can use the old subwoofer with the new system?


    Yes, you use a subwoofer cable and hook it into the mono rca jack in the back of the sub. or you can use a Y splitter 1 female to 2 males. or if your amp has 2 sub outputs (L&R) then use both. I do believe it's said that if you use the high level input, it's better. I forgot why...

    Oh yeah. the difference between the 2 is a high level input allows the currant from the amp to pass through the sub, thus allowing the continuation of wattage to your other speakers.
    Low level input is only taking a audio signal from the amp. No power is being sen through the connection.

    Subwoofer connection


    if this is ao powered sub, that plugs into the wall, there should be no problems, if it is powered solely by the reciever it may work fine but be sure you dont exceed amperage on the subwoofer.

    Most AV receivers do not have a built in amplifier block to drive a subwoofer, and merely provide the subwoofer output channel at line voltage. Thus, a powered subwoofer is required. Does the subwoofer require mains power? From your description, I'm guessing it doesn't. If not, it does not have a buit in amplifier, you will need to purchase a monoblock amplifier, which is just a mono amplifier with a volume control, no tone controls or anything else. Make sure that the amplifier power rating is as close as possible to the subwoofer power rating, as it is quite possible to blow a speaker by using an amplifier whose power output is too low, by overdriving the amplifier , and putting DC through the voice coil when the amplifier clips. If it does require mains power, it will have an amplifier built in, but does not have line level inputs.
