#1 speaker not making any noise
If the speakers didn’t make any noise, obviously you may need to check wires. If it is not plugged properly, it won’t work. If anyone side of the speaker works and another side not working, try to switch the wires to solve the issue. To check the ohms between the positive and negative leads to the speaker, use a multimeter. The range should be between 1 and 16 ohms, if it is 0 or infinity there are likely problems and the speaker may be blown.
Active or Passive?
When you start to repair, check whether the power cord is plugged in an active speaker. And for the passive check, the amplifier is on and sending the signal. You may need to diagnose the problem if the amplifier part is broken. But, if the amplifier is working and the speaker is just blown, you should repair or replace the speaker.
#2 Speakers making a funny noise
If your speaker makes a funny noise, take off the grill and figure out the speaker cone. Look for problems like cracked or loose parts. Gently push the speaker in without applying power. If there are any loose pieces of dust cap or rubber surround or if you hear a crunching noise, you may glue it with epoxy or super-glue.
Replace speaker driver or tweeter
One of the easiest ways is to obtain a replacement tweeter or woofer. Search for a model online and get reliable parts.
Reckoning a speaker
Make sure that the voice coil, speaker cone as well as rubber surrounding are in a good condition. If any of the parts are damaged, replace them.
Cleaning it up:
Clean all traces of the old speaker cone. Peel off the entire outer surround or gasket as well as the cone and the voice coil by using a razor blade or scraper tool. There is a crinkled piece of wavy material under the speaker cone that serves to suspend the speaker cone. It may be called a spider sometimes. As well as, clean out the air gap in the magnet. Clean all pieces of the cone and surrounding rubber with the recon kit obtained from the manufacturer.
Prepping the area for gluing:
Clean the outer and inner area of a speaker and pre-assemble the voice coil and driver. Make sure if all the areas are covered otherwise use glue.
Assembly and glue:
Assemble the speaker cone and voice coil, as well as the dust cap and spider by applying adhesive. Attach the metal frame with the new speaker and also reattach the positive and negative terminal of the speaker. Refer to the manufacturer’s guidelines and assemble it.
Letting it all dry:
Let the speaker dry and then test the speaker voice coil by pushing the cone in and out with your hand. If something is rubbing or scraping, you need to tear it out and check the gap for foreign material.

4. Gain access to the wire connectors that attach the terminal block to the driver by lifting the driver from the enclosure. Carefully remove the wires from the rear of the driver or the terminal block by using pliers. Make sure that the internal wire is clipped or soldered.
5. To access the internal parts, remove the crossover network from the unit and access inside the unit once the main driver is removed.
6. Test the unit’s fuse by using a multimeter
7. Test resistance by using the multimeter,
