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 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.

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
