Question about JBL S120PII Subwoofer

1 Answer

Subwoofer not powering enough (Sounds like under powered 8inch)

When I have my subwoofer hooked up and have it cranked all the way on the sub output, it barely pounds or does anything except for it sounds like its being somewhat medium powered. Even with HIGH bass music it dosent sound correct. Almost like it Distorts sometimes or even dosent even pound. I used to own the 10in version of this sub but used warranty when that one blew. Someone please tell me why my sub isnt acting like it should.

How to hook up a Kenwood subwoofer to a pioneer receiver


It depends on the speaker and receiver inputs/outputs. If The speakers have bare wires, and the receiver has spring clamps, you are in luck! Check out what I mean by spring clamps in the image linked below. If you can give the model number of the receiver and describe the wires coming from the subwoofer, I can help a lot more.

How to hook up emerson subwoofer sw 03


For powered sub :If your receiver has a sub woofer output on female RCA plug, that is the way to go. If no output you will have to get a speaker line to line output converter to then connect to your subwoofer amp input.

Unpowered sub - just hook up across the speaker terminals for each channel making sure that you hook it up in phase.

HOW TO HOOK UP SDAT 8


You need a long enough subwoofer cable ( Male connectors on each end ) and connect it to the female RCA input on the sub and the rear of your receiver has an output labeled subwoofer out connect the other end of the cable there and you are good to go. Make sure both the receiver and the subwoofer are powered off when making the connections.

How to add a subwoofer?


Car systems and home systems are different in the fact that the car system expects to receive 12 volts DC for power, and they are usually 8 ohm speakers. I would not recommend doing this unless you are in the mood for some serious config. Power converter from 110 AC-12v DC and big enough to handle the amperage. If it's not powered, then your going to be running a 4 ohm speaker on an 8 ohm amp output. Again, not recommended.

I am trying to hook up a powered sub woofer to a yamaha rx-v461 and i dont know what cables go where on the back of the sub there are two speaker ports and there are two plug ins but each speaker port has...


Your subwoofer probably has both high-power inputs and "normal"low inputs. The first are for receivers, which don't have link-level output for sub, so they are able to take already amplified signal as input.
You need to use link-level input of your sub and connect it to subwoofer-output of your receiver. The output is marked as OUTPUT - Subwoofer and is black-color RCA plug (don't confuse with subwoofer INPUT under MULTI CH INPUT).
Receiver has only mono output for subwoofer. If your sub has stereo input (white/red RCA plugs), connect just the left channel to the receiver, it will still work.
Don't connect anything to the speaker output on the sub, you don't need that.

Can't get my Accurian subwoofer to work


Sounds like you have everything hooked up properly. Make sure the outlet is providing AC power to the sub. Check the power switch on the sub.

If it is not working still; bring it back and swap it for another one before you warranty runs out.

Connect powered subwoofer


  • 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.

    SA-AX720 no subwoofer signal?


    THIS UNIT HAS NO SUB WOOFER AMP IN IT. THE ONLY WAY TO OVER COME THIS IS TO HOOK THE LEFT AND RIGHT FRONT SPEAKERS STRAIGHT TO THE SUB WOOFER AND THEN GO FROM THE SUB WOOFER BACK TO THE INPUTS ON THE BACK OF THE UNIT FOR THE FRONT SPEAKERS. THE SUB WOOFER THIS WAY WILL EXTRACT THE BASS AND THE FRONT WILL RECEIVE THEIR PART. THIS SOUNDS CRAZY AS HELL I KNOW BUT THAT'S HOW I GOT MINE TO WORK. THE OUTPUT FOR THE SUBWOOFER IS USELESS AND PUT THERE FOR YOU TO HOOK UP AN AMP FOR A SUB WOOFER. EVERYTHING HAS SHORT COMINGS, AND THAT'S THE ONE FOR THE AX-720.

    Cerwin vega ht-10d subwoofer won't work in yamaha reciever


    Well, as I know, your Cerwin Vega subwoofer is designed for use with stereo systems. Therefore, it has only 2 channels for input, and 2 channels for output as well. However, you can try this out; the first thing I suggest is that you hook up your main front channels through the subwoofer. All you have to do is to connect the subwoofer input to the front channel output on the amp, then hook up your front speakers to the satellite output on the subwoofer. As long as you make sure that system is working on 8 ohms, I believe this can activate the subwoofer.
