JVC CS-DR421 4in 4-speaker car speaker bundle

SKU CH-ZXAA-CARM7

Two pairs of 4-inch two-way coaxial speakers rated at 220 W peak and 35 W RMS each, with carbon mica woofers and balanced tweeters covering 114–23,000 Hz

  • TypeSpeaker
  • Factory upgrade with 220 W peak power per speaker
  • Carbon mica woofer cone delivers robust bass
  • 1" balanced tweeter sharpens high frequencies
  • CEA-2031 compliant for reliable performance
  • 4-ohm impedance fits most car audio systems

Upgrade for factory speakers

This bundle supplies two pairs of JVC CS-DR421 4-inch coaxial speakers built to replace original equipment. Each unit uses a carbon mica woofer cone and a 1-inch balanced tweeter for clear highs and defined lows. The 4-ohm impedance matches most factory head units without extra wiring.

Sustained output stays clean

RMS power is rated at 35 watts per speaker and 70 watts per pair, so the system handles continuous playback without strain. CEA-2031 compliance confirms the ratings follow an industry standard. Sensitivity of 88 dB means adequate volume from modest amplifier power.

Shallow mount depth fits tight doors

Top-mount depth measures 1-13/16 inches, letting the speakers sit in many factory locations where deeper units will not clear. Frequency response spans 114 to 23,000 Hz for full-range coverage. Buyers needing component separation or larger cones should consider other designs.

Questions about this item

How much heat or power draw should I expect from the CS-DR421 speakers when they run all day at high volume?

The speakers handle 35 W RMS each and present a 4-ohm load, so the amplifier — not the speakers — determines heat and current draw during extended use.

What amplifier or head-unit power rating do I need to drive the CS-DR421 speakers properly?

Each speaker is rated at 35 W RMS at 4 ohms; choose an amp or head unit that delivers roughly 35 W RMS per channel into 4 ohms for clean output.

Will the 1-13/16 in top-mount depth of the CS-DR421 fit the factory speaker locations in my older vehicle?

The 1-13/16 in mounting depth fits most standard 4 in openings, but verify your door or dash cavity depth before installing.
