Kicker 43VC124 Comp 12" Subwoofer In Vented Sub Box Enclosure, 4-Ohm

The Kicker 43VC124 is a single 12-inch Comp subwoofer preloaded in a vented MDF enclosure with one round port and a single 4-ohm terminal. The port is the reason to choose it: vented loading raises output in the low bass region, so the box plays louder and digs deeper on the same 150W RMS than a sealed alternative of similar size. Frequency response starts at 27 Hz and sensitivity is 90 dB, which means a modest mono amplifier produces noticeable low end. The sub uses a thick polypropylene cone, a high-density UV-treated rubber surround, 360-degree back bracing, and a high-temperature voice coil, a combination that handles long sessions at volume without thermal or mechanical failure. Power handling is 300W peak and 150W RMS. The enclosure is high-density MDF in a black carpet finish that fits sedan trunks, hatchback cargo areas, and SUV floors, and the single-terminal wiring keeps installation to one run from the amplifier. It is a straightforward first subwoofer for someone adding bass to a factory or upgraded system.
