CRW12D4 Subwoofer + dB11 Amplifier + RWK81 Amp Kit

This bundle brings together a Crunch CRW12D4 12-inch subwoofer, a Rockville dB11 mono amplifier, and a Rockville RWK81 8-gauge wiring kit, covering everything needed for a single-sub bass upgrade in one order. The CRW12D4 handles 400 watts RMS and 800 watts peak through a dual 4-ohm voice coil, with a powder-coated steel basket and vented aluminum former that keep the driver stable under sustained bass output. The dB11 backs it with 350 watts RMS (1400 watts peak) at 2 ohms, Dyno-certified so the rated power reflects real performance rather than an inflated peak number. A fully adjustable 12dB crossover and bass equalizer let you tune the low end to the enclosure, and the included bass remote gives in-cabin control over output. The RWK81 kit rounds out the bundle with 100% copper RCA cables, 8-gauge power and ground wire, an 18-gauge remote lead, and a 60-amp AGU fuse, plus wire ties, ring terminals, and split loom for a clean install. Since the wire, amp, and subwoofer are sized to work together, this bundle removes the guesswork of matching gauge and power ratings across separate purchases for a single-subwoofer system.
