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.

Questions about this item

How deep is the mounting hole for these 4-inch coaxial speakers and what clearance mistake do installers make?

The mounting depth is 56 mm; the common error is not checking door-panel clearance behind the speaker before cutting.

Which part of the 2-way coaxial design will need attention first as the speakers age?

The rubber edge on the injection-moulded cone can dry out and crack over time, affecting bass response.

At what RMS power level does the 1-inch ASV voice coil start to overheat during long listening sessions?

The voice coil is rated for 30 W RMS; sustained output above that level will cause thermal compression first.
