JPS10 subwoofer capacitor replacement

I need to replace capacitor C103 in the Jensen JPS10 subwoofer. Can anyone identify this component for me, or point me to the schematic? It's a grey plastic rectangular capacitor, apparently without identifying marks. Two similar components are labeled 63V, .18J and 1J88 respectively. All these are on the smaller component board, which seems to be an active cross-over.

many thanks

Martin

Make sure you have the polarity of the leads correct, ++, --. If you have the leads +-, -+, it may cause the speaker to be "pulled" instead of "pushed" like it is supposed to be. If they are correct, try reversing them anyway to see if that fixes the problem. There's no real harm in reversing the leads, it just won't be as efficient and the power will have to be turned down as to not cause damage. That's another suggestion, try turning down the power, if you have an amp that is overpowered for the sub, you could push it past peak and cause the bottoming out, damaging it forever.

Hum coming out of sub..need to replace power capacitors. Does anyone know which one they are or have schematic to share?


The power capacitors should be marked. Many places online to buy them but steer clear of the "made in China" components. You might be able to get them locally, as well.

Jensen QX-80 keeps cutting out even when on low volume. Have tested another SW and that worked fine so leads, speaker amp ok. Tried audio out from blue ray and same problem, the other SW was fine, the QX...


If I understand you, you're observing the speaker cone moving in one direction without any input. That would say the internal amp is malfunctioning and pushing DC to the speaker. Beyond that I can't say, but it is endangering the driver.

Jensen jps10 subwoofer: ******* Noise - your subwoofer is bottoming out, means its reach the limit of the voice coil and gone a little bit beyong it's limit. So what is the solution to bottoming out?

It makes a ******* sound


the capacitors probibly got to hot, try replacing them with the same value, unplug the sub and remove the metal cover at the back to see the amp curcuit look at the capacitors, if the aluminum cans look like they are swollen and ready to pop they are bad

When I plug the oudio cable into the sub woofer I get a hum in the system.


Try a different cable, make sure the cable you are useing is not a" twisted pair technology" cable, I have had that type of cable create a hummm in many subwoofers that I have troubleshot. Good luck !

See if any electrolytic filter capacitors are blown (bulged at the top), badly soldered or if they have broken contact pins (legs), a loud hum in the audio suggests there is a non rectified (AC) voltage present which could be caused by a bad or badly connected filter capacitor.

There may as well be other reasons for the hum (a bad earth connection,a loosely plugged or badly soldered audio or internal connector, bad rectifier bridge or diodes, as the case may be, bad solder joints on any component, possibly other components that are faulty).

I just suggested some of more common possibilities.

Hope you can fix it.

Basscube 10 dead...need zener and resistor help


The zener diodes are 1N4774, I believe they are one watt. Try 3 watt metal oxide for the resistors. You might as well replace the 6800uF 63 volt main filter capacitors and the 220uF 50 volt capacitors while you're at it. Half the time the heat that cooked your other parts takes them out as well.
