The voice coil on the speaker is toasted. The insulation on the voice coil wire has bubbled and now the coil is stuck in the magnet pole gap.
This is not user repairable. Caused by over driving speaker with excessive current that it was not designed for.

You can place speakers on shelves or on/in a low cabinet or entertainment center. Some speakers are better suited to this arrangement than others. "Acoustic suspension" sealed satellites are the most appropriate. Next best are ported speakers--as long as the ports are located on the front of the cabinet. However, speakers with rear-mounted ports won

Tar like adhesive has gone sticky round speaker cones and volume has droped


The tar like sticky substance is the suspension of the speaker cone and there is nothing wrong with that. Its doping compound applied by the speaker company to damp the speaker ( Was it not always there? ) If the suspension has come off the bass notes will flutter, if not its some other problem. Play some music and put your ears near the tweeters flared horn to see if they working. Nearly 30% of your sound comes from the upper part and if you have damaged it there will be a volume drop.
These speakers are quite complicated on the inside. It has two amplifiers, one for the woofer and one for the tweeter. It also has a digital sound processor. Any thing could be at fault, even a simple wrong setting.

My surround disintegrated should i replace the surround or get a new speaker.


You could get to buy the right size and suspension material, a good one from a spare shop dealing in speaker diapharam, coils, spiders and surrounds. If you can paste the suspension without removing the coils it would be good. but if the spider had come off, remove the coil/paper carefully, fix the suspension, use a thin film inside of the coil insert to centrallise the coil between the magnets and paste the spider/ suspension after removing the film. The speaker must move without any rubbing to finalise your fixing. allow it to dry, connect the coils and test. You must take patience and time to get this right and you can. Do not park your car in open sunlight/ accumulating dust, to reduce further weathering. Good day

I have a kicker 05cvr122 and the rubber around the outside got punctured how could i get that fixed?


The foam suspension often goes bad and turns to powder with age. There are kits to REPLACE the suspension but it requires some skill to do it. Often the center dome must be removed to allow shimmming the voice coil for centering while replacing the suspension foam. If you are not skilled in this, best take it to a speaker reconing service. Most pro speakers do NOT use the foam, but a fabric flex material.

How to replace rear shocks on 96 bmw 328i


Inside the car carefully pry up the speaker covers off the rear parcel shelf and undo the two screws that secure the speaker assembly onto the shelf. Release the clip and carefully from inside the boot pull the speakers away and disconnect the speaker connections
Open the boot and remove the carpet from the rear "wall" by unscrewing the 4 retaining "nuts" at first by hand and then using a phillips screwdriver.
bootcarpet.jpg

Lift this out and lift out the floor carpet. Carefully pull the side carpets away from the boot interior. They are held in 3 places : on one of the retaining bolts by the rear carpet, by a metal ledge at the top near the rear lights and by the ledges on the plastic parts in the boot.

Jack up the car and chock the front wheels so it can't roll anywhere. Also put something underneath the wheels so they cannot drop down when you undo the shock mounts.
reartower.jpg
Using a 13mm socket undo the two top shock mounts ONLY once you have supported the wheels so that you dont put stress on the suspension arms. Pry off the rubber dust cover.
shocklwrbolt.jpg
Undo the lower shock retaining bolt and carefully lift the entire shock away from the car.
oldcompleteshock.jpg
The old knackered shock and shock mount!
undotopmount.jpg
You need to recover the lower cup, upper cup and bump-stop from the old shock. To do this you need to remove the top mount from the old shock. If you look at the top of the piston it has a flat section to it. Get a set of mole grips and clamp them onto the flat section, do this as tight as you can so that you dont round it and using and adjustable spanner undo the piston retaining nut whilst holding the piston shaft using the molegrips.
keepthesebits.jpg
You need to recover 3 pieces from the piston shaft. 1- the bump stop, 2 - lower cup, 3 upper cup. Using the new shock mount as a template cut out a gasket from cardboard (the box the mount came in is ideal) to go between the upper shock mount and the suspension tower. Incidently according to the haynes manual this is made of rubber but mine was made of card! under no circumstances put the upper shock mount directly into the suspension tower.
newshock2.jpg
Put the 3 pieces onto the new shock and tighten the piston nut to secure the shock mount and put your new gasket onto the upper mount.
reartowernoshock.jpg
Use the opportunity to clean the suspension turret - do the top and the underneath making sure it's all clean and dry.
Put the new complete assembled shock into the suspension tower and either get someone to do up the top bolts a few turns or rest the bottom of the shock in the inner circumference of the wheel and lift it into position by lifting it up using the piston nut and then do the bolts up a few turns.
Bolt the bottom shock bolts back into place after putting some nut-lock on the threads and tighten them up securely, then tighten up the top mount securing bolts and put on the rubber dust cap.
bootcarpet.jpg
Put the side carpets back in making sure the speaker cables aren't trapped behind, putting in the end nearest the tail lights first making sure it's behind the retaining ledge both at the top and the end. Then do the centre section and finally over the bolt at the rear of the boot. Put the rear carpet back in and do up the retaining nuts. Reconnect the speakers and engage the lip and push the speaker up until the clip clips into place and do up the securing screws and clip the speaker cover back on.

I think that one reason for a speaker to rub is due to over heating of the voice coil. This happens when power is applied to the speaker that is greater than the speaker is capable of handling. A second cause could be that the suspension and or cone is damaged or degraded causing the coil to be tilted or off center. In either case nothing short of rebuilding the speaker can be done to repair the speaker. Rebuilding would involve removing the cone and voice coil and replacing with new items. If you were talented you might be able to repair the existing cone or voice coil but the results could be iffy.

To remove the stapled grilles, have a look at:

To go further and remove one or several drivers, remember that these speakers are air-tight (acoustic suspension); Don't break gaskets.
