Experiencing distorted sound from your car stereos can be frustrating, especially when you’re trying to enjoy your favorite tunes.
A blown speaker often results from playing loud music, leading to damaged speaker cones or the need for a new voice coil. This guide will help you diagnose and fix blown speakers, ensuring your car’s sound system delivers crisp and clear sounds. Understanding how speaker damage occurs is crucial for maintaining audio quality.
Whether it’s due to worn-out components or excessive volume, addressing these issues promptly can save your speakers and enhance your driving experience. Dive in to learn the steps to restore your car’s audio excellence.
What is Blown Speaker?
A blown speaker refers to a damaged or broken speaker cone, causing distorted sound or no sound at all. It’s the most common problem in car audio systems caused by various factors such as mechanical stress, excessive volume, and power overloads. Speakers work via vibration of its components; when these vibrations are too powerful for the cone material to handle, it can stretch or tear resulting in poor sound quality.
Moreover, a blown speaker can also occur due to excessive heat buildup in the voice coil, leading to melted or burnt components. This type of damage is often irreversible and requires a replacement. Additionally, damaged wires or connections can also cause blown speakers.
What Are the Signs of Blown Speakers?
Some of the common signs of blown speakers in a car include distorted or muffled sound, no sound at all, and crackling noises. When playing music at higher volumes, you might also notice that the bass sounds weaker than usual.
If your car has multiple speakers, you can easily identify which one is blown by adjusting the balance and fade settings on your head unit. If there’s no difference in sound quality when changing these settings, it’s likely that the speaker is blown.
Moreover, if you notice any physical damage to the speaker cone or voice coil, it’s a clear indication of a blown speaker. You may also experience more energy being required to produce the same volume as before, which can be a sign of damaged components.
What are the Reasons for Blown Speakers?
One of the main reasons for blown speakers is playing music at excessively high volumes. This puts a lot of strain on the components, causing them to stretch or tear. Additionally, prolonged exposure to high volume can also damage the voice coil by overheating.
Another common cause of blown speakers is mechanical stress. This occurs when the speaker cone moves beyond its limits due to powerful vibrations or impacts. This not only damages the cone but can also affect other internal components such as the surround and spider.
Additionally, using an amplifier with incorrect settings or too much power output can also lead to blown speakers. The excess energy from the amplifier can overload and damage the speaker, causing it to blow.
Moreover, general wear and tear over time can also contribute to blown speakers. This is especially true for older car speakers that have been used for a long time without regular maintenance. The components inside the speaker can become worn out or loose, making them more susceptible to damage.
Step-by-Step Guide: How to Fix Blown Speakers in Car
Now that you understand the common signs and causes of blown speakers, let’s walk through the step-by-step process of fixing them.
Necessary Tools and Materials
To fix a blown speaker in your car, you’ll need some basic tools and materials such as:
- Screwdriver (flathead or Phillips)
- Multimeter
- Replacement speaker(s)
- Soldering iron and solder (if needed for wiring repairs)
Step 1: Identify the Blown Speaker
The first step is to identify which speaker is blown. As mentioned earlier, this can be done by adjusting the balance and fade settings on your head unit. Once you have identified the blown speaker, make sure to mark it so that you can easily replace it later.
Step 2: Disconnect Power Source
Before working on your car’s audio system, always disconnect the power source to prevent any electrical accidents. This can be done by disconnecting the negative terminal of your car battery.
Step 3: Remove Speaker Cover and Grill
Using a screwdriver, remove the speaker cover and grill from the blown speaker. You may need to unscrew or gently pry off these components, depending on your car’s model.
Step 4: Disconnect Wires
Next, carefully disconnect the wires attached to the back of the blown speaker. Note down which wire is connected to which terminal for easier reconnection later.
Step 5: Test Speaker with Multimeter
Using a multimeter set on ohms, test the resistance of the speaker to confirm if it is indeed blown. If the resistance reading is too high or shows an “OL” (open loop) reading, it means that the speaker coil is damaged and needs to be replaced.
Step 6: Replace Blown Speaker
If your speaker is indeed blown, it’s time to replace it with a new one. Make sure to get an exact replacement or one that has similar specifications as your old speaker for best results.
Step 7: Reconnect Wires and Test Sound
Carefully reconnect the wires to the new speaker, making sure they are connected to the correct terminals. Once done, turn on your stereo at a low volume and listen for any improvements in sound quality.
Step 8: Reattach Speaker Cover and Grill
If the sound quality has improved, reattach the speaker cover and grill using a screwdriver. Make sure they are firmly attached to prevent any rattling or loose components.
Step 9: Repeat for Other Blown Speakers
If you have multiple blown speakers in your car, repeat the above steps for each one until all of them have been replaced.
Step 10: Listen and Adjust Volume Cautiously
Once all blown speakers have been replaced, it’s important to listen carefully at different volume levels to ensure that no other issues arise. Avoid playing music at excessively high volumes to prevent future damage to your new speakers.
With these simple steps, you can fix your blown car speakers and enjoy high-quality sound in your car again. If right speaker blown out, it’s important to address the issue immediately to prevent any further damage and ensure that your car audio system is working properly.
