(2) Autotek ATK12D4 12" 400w RMS DVC 4 Ohm Car Subwoofers+Mono Amplifier+Amp Kit

This bundle pairs two Autotek ATK12D4 12 inch subwoofers with a Rockville KRYPTON-M0 mono amplifier and an RWK81 8 gauge wiring kit, giving you a complete low end system instead of three separate purchases to research and match. Each subwoofer handles up to 800 watts peak and 400 watts RMS on a dual 4 ohm voice coil, while the KRYPTON-M0 delivers 350 watts RMS at 1 ohm, enough headroom to power both subwoofers together without running the amplifier at its limit.

A digital voltage display and a bass remote with a clipping indicator let you dial in gain on the fly, setting the amplifier right up to the edge of distortion on any track instead of guessing with a test tone. The fully adjustable 12dB bass equalizer and crossover shape the low end to fit a sedan cabin, a truck, or an SUV, so the same combination adapts to different vehicles and listening preferences rather than locking you into one tuning.

The RWK81 kit rounds out the package with 8 gauge power cable, 100% copper RCA cables, an 18 gauge remote wire, and a 60 amp AGU fuse, covering the wiring an install like this needs. Everything scales from a daily driver system focused on clean, deep bass to a setup built around SPL, since the amplifier's dyno certified rating and the subwoofers' power handling leave room to push harder without immediately hitting a ceiling.
