Question about Jensen JS1000-A Subwoofer

2 Answers

Subwoofer just stopped working. There's power but no sound.

I have a Jensen JS1000 Subwoofer. It was working fine for New Year's Eve and then the next day it wouldn't work. We use this subwoofer on a daily basis and never had a problem. The LED still turns on but there's no sound. Not even the slightest noise or vibration. I checked The Power plug, the phono plugs, and even opened up the back.There's no burning smell. nothing seems fried. The wires are all connected. The Speaker isn't damaged. I checked the fuse, it was fine but I still replaced it. Still no sound. Please help if you have any idea what this problem may be.

    I plugged the sound connectors and the humming noise doesn't go away, no sound comes from the subwoofer.

I have the same problem. My guess is that the subwoofer coil is messed up. You MIGHT have to get it recoiled. But before you do any of that get someone with a sub to play their sub in your car, if it works.... then your sub is messed up, if not.....then your amp is messed up ( trial and error ). Today i noticed my subs rubber surrounding is crooked, that may be the problem for me. Also when I press down on the sub it makes a sticking sound, like something came loose. So once i get everything opened and out ill let you all know the solution. Good Luck!

I have a Sony STR-DE597 FM/AM Receiver .It has audio out plug and i have a Jensen js650 100 watt Subwoofer. how can i hook them up? Thanks.

The Jensen JS650 does not accept line level input so you need to use the Front B speaker output from your Sony receiver and not the RCA subwoofer output. Even though your subwoofer is active, it does not support line level (RCA) signals.

Just connect the subwoofer as you would a pair of speakers. Once connected, you make sure the front panel speaker switch on the Sony is set to A+B so you get sound from your existing speakers (A) and subwoofer (B).

I hope that works for you.

Why is my Jensen SPX-17 home entertainment subwoofer only putting out about 10% functioning base power volume level and loudness?

Gary, If you have the subwoofer open, what did you keep from measuring the voltage of both power supplies? And while measuring, why not put a load on both, and see what current they can handle?
When the error moves with one component (power supply) the error must be there. Without a multimeter, (I have several, but I'm not close to the power supplies) you can't tell if the power supply is working to full performance. So start there.
Just try to find out, if a part of the rectifier is defect (one diode) It won't be possible to point out what is wrong, if you can't measure on the device yourself.

I have a Jensen KS212 and I'm connecting it to a home theatre receiver direct to see if it works but nothing comes out of it. Does this mean the sub is not working or there's not enough power from...

Hi, welcome to FixYa..

Your subwoofer requires a seperate amplifier that has low pass filter in the pre out system, which means it will allow all low frequency signals from the input section of the amplifier/ crossover. Your receiver has combined signals of high, mid and midbass signals that will not be able to drive your subwoofer. That is the main reason why some receivers has "Subwoofer Out" to allow you to use "Active Subwoofer systems" (also known has self powered or has a built in amplifier w/ subwoofer)
For you to use your Subwoofer, it must have a seperate amplifier, connect it to Sub out of your receiver and from there you can hear the difference. Hope this helps.

No sound fuse good lite comes on

Chances are the main output semi-conductor has failed. It will be largest of the parts and might be on a heatsink. If it is an IC, 9 times out of 10, I would say it's gone.

Dont know how to wire a subwoofer


The Jensen XS1010 is a 4-ohm sub and should work properly off of the outputs of most any single channel monoblock sub amp or off a bridged 2-channel. You did not say what brand or type of amp you intend to use, but in any case, there's only 2 wires to connect to the sub, one positive (+) , the other negative (-). Simply match them up with the positive and negative on the amp speaker output and you are ready to bump.

Here's the link to Jensen's website:

I'd recommend downloading the XS1010 manual. They recommend an enclosure with at least .75 CuFt internal volume.

If this helps, please rate it as "FixYa". Thanks!
