Question about Audio Players & Recorders
I would like to find a replacement speaker for the V2B Volkswoofer. It is a 12" speaker, with a integral amp (250 watts)
SOURCE: JVC Subwoofer problem.
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.

Looks like a broken copper braid that links the speaker terminal to the cone (from there on it goes to the coil which is underneath the cone).
Check the speaker connection terminals (near the magnet), you will notice that each terminal has a copper braid wire going from that terminal to the speaker cone.
Inspect both braid wires carefully at each end (near the speaker terminal and near the speaker cone), there will either be some damage to the braid at one or more of these four locations or the braid could be actually broken at any of these spots.
The braid can actually be resoldered at the point where it's damaged or broken - this task will require good soldering skills, mainly because this kind of braid wires are difficuld to solder (they are a bit difficult to clean because of their structure and solder won't attach itself well to oxydized copper), but also because some speaker cones are made of plastic which may melt if you overheat it with a soldering iron.
Besides that, when resoldering is being done, only a very short portion of the braid should be wetted with solder because the solder point will become rigid when the solder cools down, and the braid needs to remain very flexible when the speaker operates (if it's too rigid or too short, damage to the speaker cone could occur or the braid could get broken again when the speaker will be playing at a loud volume).
Hope you can have it repaired, it can be done at home, but there are also speaker repair shops where you can get it done (i'm not sure about the prices though).
Anyway, the alternative is to replace the speaker itself.

I'm assuming your amp for testing was NOT a subwoofer output. I could be wrong.
Your source is responsible for creating LFE output. Are you sure it's doing that?
Tune an FM station and connect any other active RCA output from the source (like a Tape Out) to the sub
