43C124 Comp 12 Inch 300 Watt SVC 4-Ohm Car Audio Subwoofer

The Kicker 43C124 is a 12-inch Comp subwoofer built on a single 4-ohm voice coil, designed for drivers who want strong, consistent low end without the added wiring options of a dual coil sub. A thick polypropylene woofer cone and 360-degree back bracing keep the cone from flexing at high excursion, while a bumped back plate and perimeter venting help manage heat and airflow during extended playback. A high-density UV-treated surround and a large magnet structure with a high-temperature voice coil support a recommended power range of 100 to 150W RMS, topping out at a 300W peak rating, so it works well with a mid-size mono amplifier. Sensitivity sits at 88.3dB with a 27Hz to 500Hz frequency response, weighted toward the low end where a subwoofer's job actually happens. Kicker recommends running the 43C124 in a sealed or ported enclosure for the strongest results, and the sub fits an 11-inch mounting cutout at a 5-7/8 inch mounting depth. Box volume ranges from 1.25 to 3.5 cubic feet sealed or 1.75 to 2.25 cubic feet vented, which gives installers some room to work with depending on available trunk or cabin space. It's a dependable single-sub option for a straightforward bass build or a factory subwoofer replacement.
