You see that black round on the middle, ussually they put name print (infinity). You have to take that to access the voice coil. You can use a soldering iron to heat up the adhesive but make sure you dont burn it. Use a low wattage soldering iron.

My 12" jl W6 v2 has a bad voice coil. What parts am I going to need to fix it?

Figure out if its a blown coil or damaged cone

1. Blown Coil:

The voice coil is the component, which amplifies the current run through the speakers. If you doubt that the coil is damaged, connect the terminals of the coil to a multimeter, and if there is no resistance detected, it could be because the coil is damaged.

2. Damaged Speaker Cone:

If there are no issues with the coil, the next possibility can be a damaged speaker cone, which can be detected easily. In normal condition, since the subwoofer is built on a suspension system, the cone is easy to move. Look for the following signs to understand that your speaker cone is damaged:
  • If you could gently take the cover of the subwoofer off and check for the movement of the cone by gently pushing along the sides
  • If the cone is rigid and does not move its indicator
Once you make sure that you have a blown subwoofer, the next step will be deciding on how to replace it. Imagine if your subwoofers can be fixed easily with minimal efforts within a set budget rather than buying a new one.


1. Detaching the speakers:

Use a screwdriver to take the speakers from the place where it is mounted and take off the attached wires. After that, separate the surround and the frame by removing the glue on the frame edge by using a small knife or a sharp object like a tester edge. Be very careful when you do this because the frame edges can be damaged.

2. Separate the voice coil and speaker cone:

Using the same small knife or a tester edge, slowly take out the voice coil from the speaker cone. Cut all the terminal wires and keep the voice coil, speaker cone, and spider separately in place.

3. Fixing the new voice coil:

Clean the trapped dust particles in the voice coil gap carefully by using the compressed air. The voice coil is the piece of wire that is attached to the speaker cone, and that is responsible for amplifying the current, which is passed through the speakers. Remove the old voice coil and fix the new voice coil within the space if the problem is with the coil. Place the spider around the new voice coil, replace the spider and then the speaker cone in the middle. Don't forget to apply enough glue so that the cone doesn't come out. Let it dry for about 24 hours.

4. Fixing the speaker frame:

After it is dry, apply glue on the surround to fix the speaker frame and the cone in the right position. Now we are about to reassemble the components of the sub-woofer.

5. Fixing the wires:

Once all the components are put together in the right place, use a soldering iron to connect the old terminal wires with the new voice coil terminal wires, if the voice coil is replaced. If the new cone has no pre-attached wires, use small wires to the terminal wires, and then create small holes in the cone. Place the wires into the holes and connect them to the voice coil using the soldering iron.Now the connection is also reestablished.

Blown speaker

Your best bet here would be to contact one of these authorized dealers for advice I think.

Blown speaker cones can be fixed by Elmers glue and tissue paper, without performance degradation.Overheated coils can be rewound by the speaker manufacturer.

My subwoofer distorts/rattles. the amp isnt the problem and the wiring was done correctly. maybe the sub is blown? can anyone help me? does anyone know how to fix it? if so can the walk me through it or...

If it distorts and rattles, chances are high that the woofer has blown, which usually means the wiring around the cone overheated or the cone itself hyper-extended. In either case, it would have caused irrepairable damage.

To my knowledge, it cannot be repaired. In this case, I hope I'm wrong...

Best of luck!

Can a kicker cvr be fixed if it is blown if so how

Speaker lesson here. For space and time, I'll not get into certain nomenclature. Working from top to bottom, you have the cone, rubber surround, basket, spider, voic coil former, voice coil, and the magnet. The binding posts are connected to the tensil leads which connect to the spider and the voice coil. As the woofer is positively + and negatively - charged, it creates a magnetic field which moves the woofer up and down. There is a small gap between the magnet and the voice coil and former that's called a magnetic gap. This gap is what helps the speaker to move up and down, and creates the Xmax. The Xmax of the woofer is the maximum linear excursion the woofer can travel without causing permanent damage. With a blown speaker, normally the voice coil and voice coil former have been pushed out of the correct magnetic gap, usually around the top of the magnet. That means that the only way to fix it is to take the woofer completely apart. My suggestion is to just go and spend the money. A blown speaker is a sign of abuse, and voids warranties from the majority of companies out there to include Kicker.

My basslink worked great, son blew fuse, replaced, now sounds lik

If the speaker has been overdriven, it may have damaged the cone surround or damaged the speaker coil, causing it to 'rub' inside the magnet. To check for rubbing, you need to move the speaker cone backwards and forwards by hand and listen where the speaker coil/cone goes into the magnet. It should be silent if ok. If you can heara rubbing or grating noise, then the speaker is damaged. If the output driver on the amp is damaged it can give a distorted sound, which could easily happen if it tries to provide too much current.

Blown sub, butIdon't know why

if you use a right channel on one coil and a left on the other different frequencies are going in different directions in each channel thus blowing a coil or badly damaging it-z

Repair or replace?

If the rip or split extends from the voice coil out to the edge, the speaker may be too far gone to replace. I have repaired expensive speaker cones with epoxy cement, provided the tear is fairly small or narrow. No noticeable degradation of performance either.

Do all speakers have fuses? I may have blown one of my Bose 151 outdoor speakers, but can't find a fuse inside.

Unfortunately many speakers do not have fuses. Most likely the voice coil has opened up inside the speaker itself. You can either get a replacement driver (speaker) or re-cone the one you have. In any case, the driver needs to be replaced.

You can verify this if you use an ohmmeter. With an 8 ohm impedence speaker, the reading should be about 6 ohms. If you read a higher number or infinity, the coil is bad.


I blew out my car speaker. Can I fix it?

Yes you can if you >
The term blown speaker can have several meanings. If it was not fixable I would say it was a blown speaker.

So 1st is it a Subwoofer or a midrange.
The Sub a little easier to fix you can send it Back to the maker of the sub and they will fix it ($)
If the cone is damaged then just use silicon
if the wires + - that are attached to the basket and the cone have fried .Soilder a new coper wire on
If the voice coil has ripped silicon
and if the copper coil is melted (you can see it but the cone will not move in or out Frozen) then this is a good time to replace it

You can go online and see if there are professional Repair kits
