Description of Soundmax SX-CX420

Soundmax SX-CX420 – 4" 2-way coaxial speaker

The Soundmax SX-CX420 is specially designed to replace worn-out 4" factory speakers. With a built-in tweeter and an easy-to-drive design, it delivers clear, crisp, and significantly more dynamic sound directly from your car stereo or a small power amplifier.

Key features of the SX-CX420:

  • 40W RMS / 120W Max: High reliability and clean sound reproduction.
  • Integrated tweeter: Clear treble without the need for external crossovers.
  • Easy to drive (4 ohms): Works excellently directly with the car stereo’s built-in amplifier.
  • Standard dimensions: Fits most 4" factory mounting holes in the dashboard and doors.

Frequently Asked Questions (FAQ)

Can I power these speakers directly from my car’s factory stereo?
Yes, thanks to their high sensitivity and 4-ohm impedance, they work perfectly with the car stereo’s built-in amplifier.

Does the tweeter include a crossover filter?
The tweeter has a built-in crossover on the coaxial chassis, so no external crossover box is needed.
