ATK12D4 12" Subwoofer, Mono Amplifier & Amp Kit

This bundle pairs a single Autotek ATK12D4 12 inch subwoofer with a Rockville dB11 mono amplifier and an RWK81 8 gauge wiring kit, giving you a complete bass system sized for a single sub setup instead of a full dual sub install. The subwoofer handles up to 800 watts peak and 400 watts RMS on a dual 4 ohm voice coil, and the dB11 delivers 350 watts RMS at 2 ohms, enough clean power to run the sub near its rated limit without straining the amplifier.

A bass remote with a clipping indicator lets you set gain right up to the edge of distortion on any track, so the sub gets maximum clean output instead of a rough estimate. The fully adjustable 12dB bass equalizer and crossover shape the low end for a sedan, coupe, or smaller cabin, making the combination flexible across different vehicles rather than tuned for one specific install.

The RWK81 kit completes the setup with 8 gauge power cable, 100% copper RCA cables, an 18 gauge remote wire, and a 60 amp AGU fuse, so the electrical side of the install is covered without sourcing parts separately. Because the amplifier's dyno certified rating exceeds its stated power, there's headroom for a daily bass boost or a more focused single sub build without pushing the system past what it's rated for.
