How to check if a speaker is burned out?
A multimeter tester will help you determine if the cone or voice coil is damaged. Set the meter to ohms, make sure the speaker is off, and touch the multimeter lead to the speaker terminals.A multimeter reading of 1.0 ohm means the speaker is not blown, but an infinity ohm reading means it is blown.
A blown speaker can have visible physical damage. To check your speaker,Remove it from the amp or instrument and take a look at the cone. There must be no holes or tears.. Damage to the cone prevents it from properly reproducing your signal and often results in ugly distortion.
Speaker Test Option 1:Connect a 9 volt battery to the speaker leads, the positive lead to the positive battery terminal and the negative lead to the negative battery terminal.. If a pulse is generated in the speaker, the speaker is still working properly. This same practice also applies to the tweeter.
Blown speakers often have hissing, fuzzy, or humming sounds emanating from them. Alternatively, they may sound like they are scratching or scratching as they play. Or, in more serious cases, a blown speaker is completely dead and produces no sound.
Burned speakers can exhibit any of the following symptoms: High levels of audible distortion. Limited frequency response (especially in multi-driver designs). Low sound levels.
The most common damaged areas of a burned out speaker
Most small tears and holes in speaker cones can be repaired with a thin mixture of white glue.. Extensive damage may require re-engineering, which is a complete cone replacement best left to a professional.
Usually, when a car speaker is only partially burned, you can still get sound from it, but the sound will be distorted.. Depending on the type of speaker that failed, you may hear hiss or crackles, static or diffuse distortion that seem particularly prevalent in a given tonal range.

If you don't have a multimeter, you can test your speakersUse a 9 volt AA or AAA battery to see if the speaker is registering power. If you quickly touch the battery posts with the speaker terminals, a soft "pop" should indicate that the speaker can form a circuit and is therefore working.
Make sure the speaker cables are properly connected to the speakers and stereo receiver. Turn off any nearby electronic devices that may be interfering with the speaker's audio. Route speaker cables away from any power cables. If the problem persists, reset the receiver to factory settings.
How much does a burnt speaker cost?
The cost to repair or replace burnt out car speakers ranges from approx.US$ 300 a US$ 500. If you choose to replace the entire sound system with something a little fancier, you could pay anywhere from $800 to $1,000.
How do you check speaker output on a receiver?Set the multimeter to AC voltage, place the multimeter probes on the appropriate speaker terminals on the receiver, play a 500 Hz to 1 kHz tone and check the readings between 2.3 V and 2.5 V.
