If you're tired of listening to a blown speaker and want to fix it, this is the article for you. We'll talk about how you can tell if your speaker is blown and what steps to take in order to fix it.
Check the speaker for physical damage
Once you’ve determined that the speaker is blown, it’s time to check for any physical damage.
Check for broken wires or loose connections. Use a multimeter to test each wire connecting your speakers and their corresponding wires in your car's stereo system. If any of these wires are broken or shorted out, they will need to be replaced before you continue with the repair process.
Check for blown fuses by turning off your vehicle and opening its fuse box (usually located under the hood near where your battery is). You may need a special tool to remove blown fuses; if so, consult an auto parts store on how best to proceed after checking which fuse has been blown and what size replacement fuse should be used instead of it.
Replace the speaker if it is physically damaged
If you do not find any physical damage to the speaker, it is likely that the wiring in the amplifier is damaged. The next step would be to check for signs of physical damage on your amplifier and replace any parts that are damaged.
If your amplifiers have a separate power supply, make sure its fuse hasn't blown by checking with a multimeter or tester. If this fuse has blown, replace it before turning on the power again.
use a multimeter to test the ohms
The first step is to test the ohms of your speaker. This can be done with a multimeter, which measures voltage and current. It can also be used to test resistance, or ohms the amount of electrons that flow through a material when it's connected to an electrical circuit. This is how we are going to test whether your blown speaker needs replacing or not:
The needle on this meter shows us the resistance of our blown speaker. As you can see from my picture above, there was no reading from my blown woofer! This means that there was no resistance at all (no sound coming out), so we know for sure we need a new woofer for our system!
replace the speaker if is not working
Remove the speaker from the phone and replace it with a new one.
Test the speaker by playing music or other audio on your phone to see if it works properly.
If your speaker gets blown, you can fix it
First, check the speaker for physical damage. If it's cracked or damaged in any way, you'll need to replace it. If your speaker is working properly, use a multimeter (you can often find these in your local hardware store) to check the ohms of your speaker. Replace the speaker if it's not working and make sure that you've wired everything correctly before turning on the device again.
If you have blown speakers then don’t worry, there are many ways to fix them without buying new ones. You can easily fix a blown speaker by following the steps mentioned above.
