Question about JVC SPPWA670 Subwoofer
This sub used to go off and on but now it blew the fuse which is 1 amp, it even blew a 5 amp fuse. I experimented with a 20 amp fuse but as soon as you apply power the speaker makes a humming noise. I read the coils on the speaker itself it reads like 8 ohms. So i am guessing the problem is in the transformer or curcuit board does any one know what to points to read and test? Is this a common problem if this model?

You may have a break in the wire. You can find out by slowing moving your fingers down the wire until you notice sound coming from the subwoofer. You can fix it yourself by cutting about an inch away from the break both ways. Then cuttings some of the wire off, so the copperwire is exposed. then wrap the two copperwire ends together and seal it with elections tape. or Try replacing the 60 watt subwoofer wire.

I would suggest to buy the entire cone speaker because the inner windings is harder to find or not available.
The cone speaker part number is: CR160058-01. Try contacting this website to find the cone speaker or you could find a cheaper speaker cone with the same dimensions and wattage.
I can also send you the service manual for this subwoofer.
