W10K9D4 2-Pack + RXD-M4 + RWK0CU 2-Pack

This package puts two Rockville W10K9D4 V3 10" K9 subwoofers together with a Krypton M4 mono amplifier and an RWK0CU 0-gauge 100% copper wiring kit for a high-output bass system you can install in one go. The subs combine for 6400W peak and 1600W RMS, each featuring dual 4-ohm voice coils and V3 upgrades: Punisher-series dustcap, inner dustcap for better cooling, redesigned pole vent, and voice coil spacer. The 3" four-layer voice coils are wound with USA-made OFC wire and backed by double-stacked 185 oz magnets.

The Krypton M4 delivers 1500W Dyno-Certified RMS at 1 ohm (1000W at 2 ohm, 550W at 4 ohm) through Class D circuitry with a high-speed MOSFET power supply. A battery voltage display on the amp and a bass remote with a built-in clipping indicator let you push the system to its limits without sending distorted signal to your subs. The amp includes adjustable low-pass and subsonic filters, a 12 dB bass equalizer, and phase control. The RWK0CU 0-gauge kit uses 100% copper cable throughout for maximum conductivity, with a 200A ANL gold-plated fuse and all connectors included.
