Question about Jl Audio 12W7 Car Subwoofer

2 Answers

I have a 12''W7 JL subwoofer and I believe that I have blown it. I'm wanting to get inside it to trouble shoot the voice coil or the resistor to see if one of those are blown. I've searched the web and cannot find out to take apart the sub. I'm attempting to remove the magnet from the body! Somebody with any info please help!

Try another speaker if it works then the speaker is the culprit, if it still doesn't work then the amp is at fault

A kicker 600.1 wired to a jl w7 10" sub? Will that work?


The kicker 600.1 provides 600 watts at 2 ohms and 300 watts at 4 ohms the 10" JL W7 has 2 1.5 ohm voice coils so you will have to wire them in series. Take about 1.5 feet of 14 gauge wire and connect the positive of one voice coil to the negative of the other then the positive and negative that are left go to the amp. Your impedance should be 3 ohms and that amp should work just fine.

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,

My 12 w7 makes a noise when I push down on it, what's wrong?


first of all the coil might have overheated and slightly made the voice coil go out of round or one of the biggest problems that jl has with their w6 AND w7's is that the magnet shifts because of the glue they use if its not annoying just keep using it or you can contact jl which by the way they charge about 250 to recone it plus at least 50 to ship and i dont think they pay for shipping to send it back you pay that also

My cone on my JL W7 cone is cracked, How can I replace?


JL has good customer service, and usually you can get a drop-in replacement core/coil/former/spider. Call/e-mail the techsupport listed on their website, or contact your local dealer for replacement parts/service.

I have two jl audio 12 w6v2 running with a jl audio 1000/1 and at high volume they make a poping noise does any one know y


That popping noise is your speaker telling you to turn it down, and that your amp is too powerful for your setup. The speaker cone is moving beyond its limits of excursion and on it's way to malfunction/blown. Basically the voice coil will fry.

I have a kicker 12 xpl that wont play mabey blow how do your determan and can it be fixed I checked the connection the lead directly to speacker and the terminals ?


Here is one quick little way to test the speaker.
Disconnect the wires from the amp that go to the speaker and touch them to a 9 volt battery.
If the speaker moves and you hear a sound then it is NOT blown and if you hear nothing and it does not move then chances are you have a blown woofer.
There are of course other more technical ways to test it with a digital millimeter but the simple 9volt battery quick test is easiest.
If t he voice coil is shorted and blown then there is usually no way to fix that and you would have to replace the speaker. (Some speakers like JL Audio W7 series have removable voice coils that can be replaced but most speakers do not.)

Jl 13 w7 burnt voice coil


Nope!! I burnt up my 12W6 from supposedly under powering it. Your going to have to pay for a new coil if under factory warranty. Other wise ..... spent good money on a paper weight. Sorry for your loss, I know that I was pissed. :-(
