How to choose your car speakers?

1. Why change your car's stock speakers?

Factory-installed speakers are often of average quality, limited in frequency and power. Replacing them with higher-quality models offers many benefits:

Improved sound : better clarity, deeper bass, crisper treble.
Personalization : choice of musical style (powerful bass, hi-fi balance, etc.).
Compatibility with amplifiers or subwoofers for a complete system.

2. The different types of car speakers

There are several types of car speakers, to choose from depending on your preferences and current setup:

➤ Coaxial speakers

They integrate several elements (woofer, tweeter, etc.) into a single chassis. Ideal for easily replacing the original speakers.

✅ Advantages : easy to install, good value for money
❌ Disadvantages : less precise than an exploded view kit

➤ Speakers in exploded kit (separate)

The woofer (midrange/bass) and tweeter (treble) are separated for more faithful sound reproduction.

✅ Advantages : better spatialization, more precise sound
❌ Disadvantages : more complex installation, higher cost

3. How to choose your car speakers?

Here are the essential criteria to consider before purchasing:

✔️ Size and compatibility

Each car has specific locations (13 cm, 16.5 cm, 6x9", etc.). Check the recess size and available depth .

👉 Tip: Use our compatibility tool or contact our Multison team to find the models that fit your vehicle.

✔️ RMS power

RMS power indicates the continuous power the speaker can handle without distortion. It should be matched to your car stereo or amplifier.

Car radio only: choose models between 25 and 60 W RMS
With amp: choose speakers with 75W RMS or more

✔️ Sensitivity (in dB)

It indicates the speaker's efficiency. The higher the sensitivity, the louder the sound will be at equal power.

Good sensitivity: > 90 dB

✔️ Frequency response

A wide frequency range ensures faithful reproduction from bass to treble. Look for a model between 50 Hz and 20 kHz at a minimum.
