## Long description

The JVC CS-J420X is a round 10 cm (4") 2-way coaxial car speaker designed to upgrade in-car audio. It has a peak power of 210 W and a rated power of 21 W, a 10 cm woofer with a ferrite magnet and a mounting depth of 4.31 cm, making it suitable for many standard vehicle speaker openings while remaining compact and lightweight at 230 g.
Advantages
The CS-J420X provides clear two-way sound reproduction from a compact 10 cm driver, with a ferrite magnet that contributes to reliable low-frequency performance. Its 210 W peak handling allows compatibility with a range of aftermarket head units and small amplifiers, while the 90 dB maximum sound pressure level ensures audible output in typical car environments. The shallow mounting depth and low weight simplify installation in tight factory speaker locations.
