43C104 Comp 10 Inch 300 Watt SVC 4-Ohm Car Audio Subwoofer

The Kicker 43C104 is a 10-inch Comp subwoofer built around a single 4-ohm voice coil, made for drivers who want a straightforward bass upgrade without juggling multiple coil wiring options. An injection molded SoloKon cone and 360-degree back bracing keep the cone rigid under load, which cuts down on the distortion that cheaper subs introduce once you push past moderate volume. The optimized polyfoam ribbed surround is double stitched for durability, and Kicker's Spiralead technology weaves the tinsel leads into the spider so they hold up to the constant flexing a subwoofer goes through over years of use. A 45oz magnet structure and high-temperature voice coil give the sub a recommended power range of 50 to 150W RMS, with a peak rating of 300W, so it pairs well with a mid-power mono amplifier without demanding one of the larger units on the market. Sensitivity comes in at 86.2dB with a 30Hz to 500Hz frequency response, tuned toward the low end where bass actually lives rather than stretching into midrange territory. The 43C104 fits a 9-1/8 inch mounting cutout at a 5-1/16 inch mounting depth, and it works in either a sealed enclosure between 1.0 and 2.4 cubic feet or a vented enclosure between 1.25 and 1.75 cubic feet, giving installers flexibility in box choice. It's a solid single-sub option for anyone building a first bass system or replacing a blown factory subwoofer.
