Committed for Better Business

Having an audio system in your car provides an enjoyable driving experience as long as you have the right set of components. If you forget any of the components or find that the system performs suboptimally, look for better components to replace them.

Most of us waste our time repairing existing components properly, but you had better opt for replaceable car stereo components, which not only ensure a better audio experience but also a trouble-free audio experience.

Below is the list of replaceable car stereo components that enhance your driving and audio experience on your travels.

Main Unit (HU)

The head unit is the most vital part of a car audio system. The HU controls the volume and other audio sources in the car. A CD/DVD player is attached to the HU. These days, HUs with MP3 support are also available. These have great functionality for you to enjoy music better. You can use your iPod with the HU and you can play music. Plus, you can even connect your Bluetooth to the HU and play the music you’re currently playing on your smartphone.


An amplifier multiplies the sound produced by the system, giving you a powerful music experience. When buying an amplifier, make sure you go for a high-quality product for better performance. In addition, you can connect as many speakers as there are channels on the amplifier. Some HUs come with built-in amplifiers, eliminating the need for a separate amplifier.

main speakers

The speakers are the center of the stereo system as they are the main devices responsible for you listening to the music. Therefore, while opting for the speakers, go for the higher frequency ones.

Speakers are available in two types: coaxial and component. While the former has two units, namely the low and high frequency units, built into one physical frame, the latter has an additional part: the crossover. Component speakers offer better quality output, but are more expensive.


Subwoofers change the qualitative characteristic of the sound output of the system. So if you want to get a booming sound, you need a subwoofer. This device should be sealed in a good quality wooden box which should be kept in the back trunk of your car.


Don’t go for cheap cables when choosing cables for your car audio system, go for ones made by a reputable company. Cheap cables not only affect the sound quality, but also cause the headlights to dim when the music is played at a high volume, since the car battery is connected to HU, which is then connected via cables to the amplifier and speakers.

Generally, the amplifiers are located in the trunk of the vehicle and the HUs in the dashboard of the vehicle, therefore, you need a connection cable whose length is equal to the length of the car. Since the signals emitted by the HU are not strong, they cause typical noise. To play music alone, you need to opt for a good quality connection cable.

Professional installation is recommended.

It is always better to go for professional installation of your car audio system as certified professionals can enable secure connections for your audio components and are also good at placing them correctly. And furthermore, if you find that any component is working suboptimally, you should seek the help of a professional.

However, in any case, do not do the work yourself, or have it done by an ordinary mechanic who may cause serious damage to the audio system and the vehicle. Therefore, it is strongly recommended that this be done only by a certified professional.

The car audio system is worth spending. If you have a good one, it makes your driving more enjoyable; overcome loneliness and boredom. It’s not just sound, calm your mood while driving. So check these qualities in your system and make a proper decision.
