Product notes

What each pick is best at

Focal Auditor ACX100 - 4" 100mm 2-Way Car Door Coaxial Speakers 120W

Best overall speaker upgrade

Focal Auditor ACX100 - 4" 100mm 2-Way Car Door Coaxial Speakers 120W

A coaxial option for making a factory system clearer without changing the whole car.

What we don't like

  • Unlike some alternatives, the listing does not show a comparable power figure, so matching it to the rest of the system takes more checking.
  • The fixed coaxial layout offers less placement flexibility than a component set, and the speaker size and depth still need measuring.

A coaxial option for making a factory system clearer without changing the whole car.

What we don't like

Buying guide

What to check before ordering

Measure the original speaker opening and mounting depth. Compare RMS power and impedance with the existing stereo or planned amplifier, and check whether grilles, tweeters or crossovers are included.

Use the model number as the final reference. Retailer images and prices can change, and vehicle fitment should be confirmed for the exact make, model and year.
