48TCWRT122 12" Slim Subwoofer + Amplifier + Wire Kit Bundle

This bundle pairs the Kicker 48TCWRT122 CompRT 12-inch slim subwoofer enclosure with a Rockville dB12 mono amplifier and an RWK41 4-gauge wiring kit, covering the full signal path for anyone adding real bass to a factory stereo. The CompRT enclosure combines an active CompRT subwoofer with a passive ReFLEX radiator in a single 2-ohm-terminated box, built with thick MDF and internal bracing that holds up under stacked cargo. Forced-Air Cooling keeps the sub running 20 percent cooler than earlier designs, and the slim profile fits under a seat, behind a back bench, or in a compact cargo area.

Powering it is a 2,000W peak / 500W RMS Dyno-Certified mono amplifier at 2 ohms, with a fully adjustable 12dB/octave crossover, subsonic filter, bass equalizer, and a dashboard remote for on-the-fly bass control. The RWK41 kit rounds out the install with 100% copper RCA cables, 4-gauge power and ground wire, an 18-gauge remote lead, and a 60-amp AGU fuse, wrapped in a flexible, temperature-resistant jacket that routes easily through factory door and firewall openings.

Together, the three pieces remove the guesswork of matching sub, amp, and wire gauge separately, delivering a complete 12-inch bass system in one order, ready for a trunk, SUV cargo area, or truck cab install.
