MB1200.1D 1200W Class D Mono Amplifier with RWK41 4-Gauge Amp Kit

The Planet Audio MB1200.1D pairs a 1200W Class D monoblock amplifier with a Rockville RWK41 4-gauge wiring kit, giving a subwoofer install the amp and the cable to run it in one order. The amp is 1 ohm stable and outputs up to 900W RMS at 1 ohm, 450W at 2 ohm, or 225W at 4 ohm, so it scales down cleanly if the sub load changes. A fixed high-pass filter protects the amp's own circuitry while a variable low-pass filter, variable subsonic filter, and 0 to 18 dB variable bass boost let you tune output to the subwoofer in use, and the included remote subwoofer control puts that bass adjustment within reach of the front seat instead of requiring a reach to the amp itself. High-level and low-level inputs plus switchable input sensitivity mean the amp connects to either a factory speaker-level harness or an aftermarket RCA preamp output, and thermal and short-circuit protection shut it down safely if conditions run outside a normal range. Illuminated end panel strips make level and status visible without pulling the amp out to check it. The RWK41 kit covers the physical run: 17 feet of 4-gauge power cable rated for this amp's 1-ohm draw, a matching twisted-pair copper RCA cable, remote and speaker wire, a grounding cable, a gold-plated 60 amp AGU fuse holder, and the terminals and loom needed for a clean install. Between the two pieces, this bundle covers a full monoblock subwoofer setup from the head unit connection to the final ground point.
