KS-DR1004D Amplifier & RWB90B 8" Wakeboard Tower Speakers

This bundle pairs the JVC KS-DR1004D 400-watt 4-channel amplifier with a pair of Rockville 8-inch black wakeboard tower speakers, stepping up from a 6.5-inch driver for more low-end output at the back of the boat.

The KS-DR1004D powers the pair with 400 watts of Class-D output across 4 channels, and conformal coating protects the circuit board from spray and moisture. Variable HPF and LPF rotary controls let you fine-tune the crossover to the larger driver's range.

Each 8-inch speaker is a 2-way system with a 1-inch polyimide dome neodymium tweeter, a polypropylene cone with a Santoprene surround, and a high-density Y30 magnet for stronger bass output than the smaller 6.5-inch option. The nylon mounting bracket, reinforced with embedded steel, rotates 360 degrees and fits tower bars from 1.26 to 2.87 inches thick. Stainless steel hardware and rubber-gasket-sealed terminals resist corrosion from salt and fresh water, and the pair is rated for 300 watts peak and 200 watts RMS, delivering noticeably more volume and bass than a standard 6.5-inch tower speaker at true, CEA-tested power ratings.
