  • Car speakers are susceptible to all kinds of repair issues, depending on the design of your vehicle and the speakers themselves.
  • Start troubleshooting by listening to the speakers for a blown speaker crackling or distorted sound. This indicates a faulty voice coil.
  • When it comes to making necessary repairs, hire a pro as modern car speaker wire connections are complicated, and poor repairs lead to bad sounds and poor sound quality.

Car Speaker Repair Tips

Before learning how to fix a speaker, you have to learn what the actual problem is. There are many cars out there and many different car speakers, which you’ll know when you research the best car speakers for bass. In other words, there is no universal solution here, as it depends on the issue at hand.

Insider Tip

You should have your car speakers inspected every year or so by a qualified professional during an annual tuneup.

Here are some helpful troubleshooting steps to fix the problem of a broken car speaker, so you won’t have to look for the loudest Bluetooth speaker for that next road trip.

Test the Speakers

If you have a firm grasp of some basic electrical concepts, test the speakers to see if they are partially or fully blown. You can do this yourself with an electric meter. Set it to record OHMS (impedance) and make sure the speakers are turned off. Place a meter lead on each of the two speaker terminals. If the speaker is blown, the tool will read infinite impedance. If the speaker is fine, it will read 1.0.

Don’t have an electric meter or looking for a simpler way to get to the bottom of things? Use your ears. Blown car speakers will be fuzzy, crackly, or may not produce sound at all.

Check the Bluetooth

Your speaker may not be damaged at all. You could simply have the Bluetooth on and have the speakers send audio streams to a connected device that you are not hearing. Look through all of your recently connected devices and be sure to turn the Bluetooth off at the source, your car’s media panel. This is a good step to try when you aren’t hearing anything at all from your car speakers.


Playing your speakers at a higher than reasonable level can cause them to blow out.

Hire a Pro

Today’s cars make it truly difficult for the layperson to conduct repairs and replacements. In other words, you’ll have to hire a reputable professional to take a look at the speakers, diagnose the official problem, and install a replacement. In the vast majority of cases, it is cheaper to replace the speakers than to conduct repairs.

STAT: If you can’t feel any vibration or thump coming from a subwoofer when the volume is up, your speaker may be damaged. Place your fingers lightly on the speaker and turn up the bass. (source)
