JVC CS-J520X 5.25" 2-Way Coaxial Car Speakers - 250W - Pair

The JVC CS-J520X is a pair of 5.25-inch two-way coaxial car speakers designed as a drop-in upgrade for factory speaker locations. Each speaker pairs a mica cone woofer with a 1-inch poly-ether imide balanced tweeter driven by a neodymium magnet, producing a frequency range from 40Hz to 22,000Hz. The mica cone material provides a rigid yet lightweight diaphragm for controlled midbass response, while the tweeter adds clarity and detail to vocals and higher-frequency instruments. Together, the two-way design delivers a noticeable improvement over stock paper-cone speakers.

Practicality is a strong suit of the CS-J520X. The shallow mounting depth of just 1-23/32 inches (43.5mm) means they fit in tight spaces where deeper speakers cannot, making installation straightforward in a wide range of vehicles. A 91dB sensitivity rating ensures they play efficiently on factory head units without requiring a dedicated amplifier, though they can also handle up to 250W peak (30W RMS) if paired with a modest amp. With a 4-ohm impedance and standard 5.25-inch fitment, they are compatible with most aftermarket and factory systems, making them an accessible first step for anyone looking to improve their in-car listening experience.
