43C154 Comp 15" 500W SVC 4-Ohm Subwoofer, RXA-T1 Amplifier & RWK81 Amp Kit

This bundle pairs the Kicker 43C154 Comp 15-inch subwoofer with a Rockville RXA-T1 two-channel amplifier and an RWK81 8-gauge wiring kit for a complete bass system in one order. The 43C154 is a 4-ohm single voice coil sub with a thick polypropylene cone, 360-degree back bracing, and a high-temperature voice coil, handling 500W peak and 250W RMS in a sealed enclosure from 2.25 to 5.0 cubic feet or a vented box from 3.0 to 4.0 cubic feet. The RXA-T1 supplies 1500W peak and 370W Dyno-Certified RMS bridged at 4 ohms, with a MOSFET power supply, ELNA capacitors, and an auto-turn-on feature that fires from the audio signal, so a factory stereo without a remote lead still works. A 12dB adjustable crossover, bass EQ, and mute and delay soft start give you room to dial in the sound. The RWK81 finishes the job with 17 feet of 100% copper twisted-pair RCA cable, 8-gauge power and ground wire, an 18-gauge remote lead, a gold-plated AGU fuse holder, split-loom tubing, and the terminals and grommets to route everything cleanly through the cabin. Together these three pieces take the guesswork out of matching a sub to an amp and a wiring kit to both, delivering a noticeably deeper low end for daily driving or long trips without the trial and error of building a system piece by piece.
