4 Common Car Stereo Speaker Power Problems

Various types of auto speakers are on display

Though car stereo speakers are easy to install, they aren't always easy to operate. No matter how recent your new car audio installation may or may not be, many issues can crop up, such as sound cutting out, being distorted, or not working at all.

Whether you are interested in audiophile-level quality or just want to listen to your favorite tunes on your daily commute, these tips can help you keep the music playing in your car.

1. Connections

Whether the connection is to an amplifier or directly to the receiver, it is worthwhile to check all the connections on car stereo speakers. Because a vehicle is constantly vibrating while in operation, it is easy for connections to become loose or disconnected.

You also need to make sure that the wires are able to accommodate the entire power needed to operate the speakers. One common symptom of loose or faulty connections is that the speaker will occasionally work, cutting out from time to time, or that they will not work at all.

2. Grounding

The stereo's system ground or earth wire greatly affects the performance of the overall system, particularly the speakers. In this situation, the user may experience spotty sound from the speakers or no sound at all.

Try relocating the ground wire to a more stable location and securing it firmly, particularly if it is loose or bouncing around. If the stereo is not properly grounded, it may also pick up EMI (electro magnetic interference) from the alternator, resulting in a buzzing or whining sound that fluctuates as the vehicle’s speed varies.

3. Amplifiers

Amplifiers can enhance the sound of a car stereo system greatly. They also make the vehicle's audio system a bit more complex, and knowing how to operate the amplifier is critical to maintaining peak performance. If your car’s audio system includes an amplifier, be sure to check its connections and settings.

You may also need to adjust the settings on the amp as too much or too little power may be routed to the speaker.

4. Blown Speakers

Blown speakers have a distinct distorted sound quality and are not repairable. This may also be visibly indicated by damage behind the speaker cover. Unfortunately, the only way to correct this problem to replace the speaker.
