KS-DR1004D Amplifier & RMSTS65W White Marine Speakers

This bundle pairs the JVC KS-DR1004D 400-watt 4-channel amplifier with two pairs of Rockville RMSTS65W 6.5-inch marine speakers in white, giving a boat, RZR, or UTV a complete powered sound system instead of a head unit driving underpowered stock speakers.

The KS-DR1004D delivers 400 watts of Class-D power across 4 channels, enough to power all four RMSTS65W speakers with real headroom. Conformal coating protects its circuit board from moisture and salt spray, while separated pre-amp and power-amp boards cut down on radiation noise. Variable HPF and LPF rotary controls let you fine-tune the crossover to match the speakers exactly.

The RMSTS65W speakers step up from an entry-level marine speaker with a 1-inch PEI dome tweeter and a larger magnet rated for 400 watts peak and 100 watts RMS each. A molded ABS basket, polypropylene cone, and rubber surround are fully marinized against salt and fresh water, with stainless steel terminals that won't corrode. The swivel tweeter lets you aim the highs toward the listening position, and pre-mounted grills with included mounting hardware and 16.4 feet of speaker wire mean everything needed for the install is already in the box, finished in white to match a lighter deck or dash.
