KS-DR1004D Amplifier & RWB90B 8" Tower Speakers for RZR/ATV/UTV

This bundle pairs the JVC KS-DR1004D 400-watt 4-channel amplifier with a pair of Rockville 8-inch black tower speakers built to mount on the roll bar or cage of a Polaris RZR, ATV, or UTV, stepping up from a 6.5-inch driver for more low-end output out on the trail.

The KS-DR1004D drives the pair with 400 watts of Class-D power across 4 channels, and conformal coating protects the circuit board from dust 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 than the smaller 6.5-inch option. The nylon mounting bracket, reinforced with embedded steel, rotates 360 degrees and fits roll bars from 1.26 to 2.87 inches thick, with 65mm and 80mm screws included to match a Jeep Wrangler or ATV cage. Stainless steel hardware and rubber-gasket-sealed terminals resist corrosion from mud and rain, and the pair is rated for 300 watts peak and 200 watts RMS, giving an off-road rig real bass over engine and wind noise.
