Tips for Improving the Sound Quality in Your Car

Cars have become a modern-day entertainment hub for people on the go. Older audio systems are being replaced by sophisticated systems that make even the most dedicated audiophiles look forwards to being on the road. Here are some tips for improving the sound quality in your car.



The quality of most built-in car speakers can make it seem that sound quality isn't a primary manufacturing concern. That's why the first step towards better audio involves changing out the factory speakers. There are two common types of car speaker systems available: full-range and component.

For people who want improved sound without much fuss, a full-range speaker will suffice. It's inexpensive, easy to install, and has all the speaker mechanisms in one place. Car owners who want more advanced sound potential will want to invest in component speakers. Different frequencies in the sound will become more distinct thanks to the separated woofers and tweeters in the speakers, giving much more depth to the sound.



For people who want the music loud, an external amplifier is an essential part of the picture. Amplifiers are not just used to crank up the volume. With powerful enough wattage, amps will allow car owners to listen to music at higher volume with no distortion. Considerations when choosing an amp include power, number of channels, and system compatibility.


It is important not to skimp on power, especially for owners who have just upgraded their speakers. Amps have two ratings when it comes to power: peak power and root mean square (RMS). Peak power refers to the maximum amount of power an amplifier can produce when increasing the volume, while RMS is the amount of power an amplifier can produce with continuous use. Car amp buyers should make sure that the amp's RMS matches the power ratings of the speakers.

Number of channels

Each speaker will need one channel. A car with four speakers will need an amplifier with four channels.

Receiver compatibility

Make sure the amp is compatible with the head unit. For example, for receivers without a preamp output, amps with speaker level inputs would be better choices.


Audio Equaliser

The car's interior can impact sound quality. Plastic surfaces and windows reflect sound while carpet and seat covers absorb it. The result can be a shrill sounding treble and woofers that give off an annoying booming sound.

Factory car receivers are equipped with bass, mid-range, and treble control. While these controls are enough for general fixes, car owners need more control to kill the frequency response peaks caused by car interior acoustics. This is where an audio equaliser comes into play. This device has wider frequency range control, allowing for easier customisation of sound to suit the car's acoustics.


Sound-Deadening Material

Most factory speakers are mounted behind the rear seats and in the front doors. The thin metals in the door panel and the area in the rear seat will vibrate as the speaker produces sounds. This vibration will compromise sound quality. A good solution to this problem would be to apply sound deadening kit on these areas.

Aside from providing a more stable platform for the speakers, sound-deadening materials can also mask road noise. Sound quality substantially decreases as speed increases because road and wind noise cut out lower sound frequencies. Find sound deadening materials like Dynamat or Antivibe oneBay to solve this problem.


Power Cables

Cables direct signal flow from the receiver to the amp. Undersized and low-quality cables will compromise sound quality when the volume is cranked up. High-quality power cables ensure better flow of signal for a more focused and crisp sound.


Mind the Tone Controls

Sometimes EQ settings could spell the difference between great and crappy sound. It's a good idea to have some presets on the receiver prior to hitting the road since it's unwise to play with those knobs while driving. In addition, maxing out tone controls is not a good idea as it may put a strain on the audio system--particularly if the owner has not upgraded the factory receiver.

There are many ways to boost the sound quality of a car's audio system. A few tweaks and additional components could produce the perfect symphony that converts the car into an audio paradise.
