Subwoofer repairable?

[TLS Guy]

hmm i see i have all of the tools just no kit at loud speaker glue where should i buy the kit from... i looked on the internet but could not find anything ... how would i take everything apart? with out injurying it to bad? do i have to remove the magnet? how am i supposed to get to it? thanks!

and more thing my buddy has two 12 inch pioneer in a legit box.... but he just recently blew them and one of the subs were brand new.... they are 800 watts each running off a 4000 watt amp but its not turned up all the way or anything.... thanks so much!

I just told you how to do it. You work from the front, and now you don't take the magnet off!

You need to see if you can get a rebuild kit for that speaker, from Pioneer or a speaker repair outfit like Orange County Speaker repair.

If you know of other units that have failed, then these units are probably junk and not worth the time of day. There are a lot of junk subs out there.

Hi, I was wondering if my subwoofer was repairable.

Now, before I start off, I'm not going to lie and say that I'm some amazing professional with subs, but that's why I'm here, I guess. I figured someone on here has GOT to know a lot about subs and could help me out. The 100% honest truth, however, is that I know very little about car audio. I simply hate the fact that my sub isn't working correctly, so I took it out, looked it over, and decided I wanted to fix it. I tried looking for ways to fix it on the internet, and found this place, and thought someone could maybe help me out.

I have a JL audio 12W3-D4 Dual Voice Coil Subwoofer. It came in the truck that I bought off of my friend. The truck is a '95, so I'm very strongly assuming that the sub is newer than that. The problem is that it makes a popping sound whenever I get my sound to -20dB or above, and sometimes much lower on some songs, depending on the base levels in the song. The only time I hear it is when the song makes a thump - it's fine on sounds like low rumbles, etc. I know it's attached to Punch 600a4 amp, if that helps at all. When I took it into a shop certified to deal with JL audio, they listened to it for 5 seconds, said that it was the voice coil, and assured me that the only course of action was to throw it out and buy a new one. Well, I'm a cheap person, and I'd rather repair this than buy an all new one.

If anyone could either show me a tutorial on how to fix it, be willing to help walk me through some simple (or, if you're willing, not so simple) steps to fix it, or simply explain to me why it's gonna be pretty darn near impossible to fix myself, I'd really appreciate it. I'd just ignore the problem, but to be totally honest, it's getting difficult, because the thing seems to be getting worse as time goes on, and I don't want to hit some point-of-no-return in terms of repairs.

Thanks for any help you guys can give me!

Have you thought of contacting JL about this?

Does it pop AND scrape? If it makes a scraping sound, the voice coil is either toast or it could be that the frame is twisted. If the box is sealed, it may not be sealed well. Could be a bad joint in the box, too. I would remove the box, make sure it's mechanically sound and listen more closely. Also, I would remove the driver from the box and look it over. If the cone, surround or spider are damaged, it should be reconed or replaced depending on where the damage is. You can't ignore this kind of damage and it won't go away. If it has damage, it's already at the point of no return. If the voice coil shorts out from scraping on the magnet, it can take out the amp, too.

There's a possibility that the amp is puking because its power cabling isn't heavy enough, grounded properly or its connections aren't very good. When an amp's power supply is lacking, the amp don't operate at full spec.

TLS, I already read that post you made to that guy who was talking about how he heard that basketball against the wall thump, and the only reason I didn't simply listen to that one was because of the fact that I didn't hear any huge thump, or anything. In any case, I'm gonna take some time to look around and see if I can get it repaired cheap, and I'll check out that OC audio shop. Thanks for the help everyone! I really appreciate it.

There's a saying about having things done by someone. "You can have it done fast, good or cheap. Pick two, because you can't have all three".

If parts aren't available for it, it won't be the same as a new one. If it's not as good as a new one, what's the point of having it done at all? Other than saving money, it'll never be "right". You can't take parts from one company and use them on a speaker from another company unless they're made for the speaker, except by coincidence.

Did it sound like this from the time you bought the truck? Did you ever hear this problem before you bought it? It's possible that if the box isn't from JL, it's not the correct internal volume for that driver, too.
