5 Core CS 04 2W 4" 2-Way Coaxial Car Subwoofer Pair 250W

4-Inch Coaxial Pair for Door Panels

These 4-inch coaxial speakers mount in factory door or side-panel locations and ship as a matched pair. Each unit handles 30 W RMS and 250 W peak power at 4 ohms, making them a direct replacement for OEM drivers in cars, trucks or SUVs. The 88 dB sensitivity rating means they produce usable volume from standard head-unit power without a separate amplifier.

30 W RMS Thermal Limit and 80 Hz Low End

The single 1-inch ASV voice coil is rated for high-temperature operation so output remains consistent during extended listening sessions. With 30 W continuous power handling the thermal ceiling is modest, so prolonged high-volume use should be monitored to avoid coil fatigue. Frequency response starts at 80 Hz, giving noticeable mid-bass presence while leaving true sub-bass to a dedicated subwoofer.

Rubber Surround and 56 mm Mounting Depth

A rubber-edge injection-moulded cone resists moisture and UV exposure for long-term door-panel durability. The Y30-grade magnet structure keeps the motor assembly compact, resulting in a 56 mm mounting depth that clears most factory door cavities without spacer rings. Included hardware consists of two speakers only; installer must supply wiring, adapters or brackets if the vehicle's original harness differs.
