43C154 Comp 15" 500W SVC 4-Ohm Subwoofer

The Kicker 43C154 Comp 15-inch subwoofer is built for drivers who want a noticeable low-end upgrade without stepping up to a multi-sub system. A 4-ohm single voice coil design pairs with a thick polypropylene woofer cone, a high-density UV-treated surround, and 360-degree back bracing to keep the cone controlled at higher excursion. The bumped back plate and large magnet structure support deep bass output, while the high-temperature voice coil is rated to handle sustained power without breaking down. Peak power handling reaches 500W, with 250W RMS and a recommended amplifier range of 200 to 300W RMS, so it pairs cleanly with a mid-size mono amplifier. Sensitivity comes in at 90.3 dB and frequency response runs from 25 to 500 Hz, giving it enough range to blend with factory mids and highs. The sub fits a sealed enclosure between 2.25 and 5.0 cubic feet or a vented enclosure between 3.0 and 4.0 cubic feet, with a mounting depth of 7-7/16 inches and a mounting cutout of 13-11/16 inches, so it is worth measuring your enclosure or trunk space before ordering. It works well as a standalone upgrade for replacing a blown factory sub or building a first dedicated bass system, and it keeps the fit and finish expected from Kicker's Comp series.
