48TRTP122 12" Down-Firing Subwoofer + Amplifier + Wire Kit Bundle

This bundle pairs the Kicker 48TRTP122 TRTP 12-inch down-firing subwoofer enclosure with a Rockville dB12 mono amplifier and an RWK41 4-gauge wiring kit, built for anyone who wants serious bass without losing cargo room. The TRTP enclosure loads a passive ReFLEX subwoofer alongside an active CompRT sub in a thin-profile box pre-wired to a single 2-ohm terminal, so it fits under a truck seat or in a cargo area and holds up under stacked gear. Extensive internal bracing, thick MDF construction, and Forced-Air Cooling keep it running about 20 percent cooler than earlier designs.

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 completes 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 deliver a complete down-firing bass system, matched for power and wired end to end, ready for a truck cab or SUV where cargo space is at a premium.
