    Chances are it is not overheating - its that its being over-driven.

    Are the subwoofers in seperate or common enclosure?

    Sealed or vented?

    If they are contacting anywhere on the basket during play, it will cause a short and melt the wire.

    We have had many problems with JL and tinsel lead length.

    Inspect the basket and see if there are char marks.

    RePost so I may help you further investigate.

    Those subs are 300W RMS, and you're giving them close to 400W ea.

Check the impedences. How many ohms are you running each speaker at? Are they both wired the same?

Also after repairing unless it's done by a true professional normal solder will not work.. it doesn't flex as well as it does from factory, and it's very hard to extend tinsle lead length, I would suggest returning to original store for swap or return to JL for swap.. (or get new ones.... not JL :) )

I have an amp hooked up in my car.when I tried to connect the two woofers up to amp, the stereo cut off and the deck said protect.now that's all it will do is read protect.Wat do I do?


This is a circuit protection to stop you frying your audio! Could be a short circuit or wired wrong......remove the fault and it should reset! First remove the 2 sub woofers since that was when this happened and test the deck!

I think its my voice coil but I might as well ask to make sure. At higher volumes, my W7 will make a wierd rattling sound from inside the sub. Is it the voice coil or something else?


tinsel lead on terminal needs to be coated with a layer of black rtv sealant where it comes out of voice coil on back of speaker temporary fix since you have OVERPLAYED your subs,

How can i fix a focal sub that does not get current threw one voice coil?


Sorry I do not believe that sub to be rebuildable. You can try running the sub with only 1 voice-coil but either way I think it is time for another sub unless it is a de-soldered tinsel lead (where you connect your wires to the sub).

My wire got pulled off my sub how can i fix it


Hello gatmanfromda,

I'm assuming you mean the "tinsel" lead going from the connector to the sub cone. In many cases, the wire can be soldered back on. It takes care and patience and you need to be sparing with the solder and prevent it from stiffening the tinsel lead. Otherwise it will tear out again when the sub cones moves out. If the cone itself was damaged when the lead pulled off, you can use silicone sealant to repair it. Again, be sparing with the silicone and allow it 24 hours to set up before trying to operate the sub. If the wire pulled off from the connector terminal, just solder it back on.

Hope this helps.

The positive wires are snapped how do i fix it


Hello gosecoa,

The tinsel leads can usually be soldered back on OK. You may need to remove a small amount of the sleeve. Make sure that your soldering iron is clean and well tinned. Hold the tinsel lead gently in position with a nonconductive tool and apply the soldering iron to the edge where it meets the solder pad on the back of the sub cone. After the solder has melted (usually you won't need to add any additional solder), remove the iron first and continue holding the lead into place until the solder hardens.

Hope this helps.
