Package Includes: (1) Rockville ATOM 8B 8 Channel 3500 Watt Peak/880w Dyno-Certified RMS Marine/Boat Amplifier Amp w/Bluetooth; (1) Rockville RWK42 4 Gauge 4 Chan Car Amp Wiring Installation Wire Kit (2) RCA's — official bundle contents for this listing only. High-Power, Compact Performance (ATOM 8B): Class-D 8-channel design delivers serious output in a small footprint: 70W x 8 @ 4Ω, 110W x 8 @ 2Ω, or 220W x 4 bridged @ 4Ω. Wide 10Hz–30kHz response, >95dB S/N, <0.05% THD for clean sound across cabins, cockpits, and wake towers. Built-in voltage display and RCA line out simplify multi-zone setups on today’s boats without bulky gear or excess wiring. Marine-Grade Build That Lasts (ATOM 8B): Purpose-built for water with conformal-coated PCB, stainless steel bottom plate/end caps/hardware, and UV/salt-water-resistant enclosure printing. Four-way protection (DC/short/thermal/overload), mute/delay soft start, and an 80A fuse rating help protect speakers and electrical systems. Durable finish resists corrosion season after season for confident marine installations. Flexible System Tuning & Expansion (ATOM 8B): Independent crossovers for CH1-4 and CH5-8 support Full/HPF/LPF with 12dB/oct slopes and 50Hz–250Hz adjustability—ideal for dialing in full-range, mids/tweeters, or subwoofers. 4CH/8CH input selector lets limited head-unit outputs feed all eight channels. Bluetooth with auto pairing adds convenient streaming when your source is stowed, perfect for sandbars and dock-side gatherings. Complete, Copper-Focused Install (RWK42): RWK42 includes true 4-gauge SuperFlex power/ground, (2) 17' twisted-pair 100% copper RCA cables for low-noise signal, remote wire, speaker wire, AGU fuse holder with 100A/60A fuses, loom, and accessories. The soft, abrasion-proof jacket routes cleanly through tight runs; copper-rich construction lowers resistance to deliver steady current so ATOM 8B performs cooler, louder, and more efficiently on the water. This Rockville Marine Amplifier and Wiring Kit Bundle combines elite audio power with premium-grade installation tools—perfect for serious marine and powersport audio systems. Built to outperform in challenging environments, this system provides exceptional sound quality, durable performance, and all-in-one convenience.
