Package Includes: (1) Rockville ATOM 8W 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. Marine-grade power & control: ATOM 8W drives multi-zone systems with 3,500-Watt peak / 880-Watts Dyno-Certified RMS across 8 channels. Efficient Class-D topology, Bluetooth with auto pairing, voltage display, and 4CH/8CH input mode simplify daily use. Independent 12 dB/oct crossovers (CH1-4 & CH5-8) support full/HP/LP at 50Hz-250Hz with 0-12 dB bass EQ @ 45Hz, S/N >95 dB and <0.05% THD for clean, controlled output. Flexible zone configurations: Run 8 full-range speakers, mix mids and tweeters, add 2-4 subwoofers on CH5-8, or bridge to 220-Watts x4 @ 4 Ohms for tower or cabin channels. Independent filters tailor each bank; damping factor >150 @ 100Hz and channel separation >45 dB improve control and stereo imaging. Wide 10Hz-30kHz response and 280 mV-7 V input range integrate with common marine head units and DSPs. Built for harsh marine environments: Conformal-coated PCBs resist moisture and salt spray; UV and salt-water resistant finish, stainless steel end caps, hardware, and bottom plate fight corrosion. Non-corrosive RCA inputs and bolt-down block terminals keep connections solid. 4-Way protection (DC, short, thermal, overload) with soft-start, mute, and delay safeguards gear; compact 6.7" W x 2" H x 10.8" L chassis fits tight helm spaces. Complete 4-AWG install kit (RWK42): Includes two 17' twisted-pair 100% copper RCA cables, SuperFlex 4-AWG power and ground, 16-gauge speaker wire, 18-gauge remote wire, gold-plated AGU fuse holder with 80-Amp fuse, split-loom, and install hardware (ties, rings, spades, butt connectors, grommets). Soft abrasion-proof PVC jacket improves routing and resists oil; color-coded cables speed a neat, serviceable installation. Power your boat's sound with a compact, high-output system built for the water. This bundle pairs the Rockville ATOM 8W 8-channel Class-D marine amplifier with the RWK42 4-gauge wiring kit, giving you the clean power, corrosion resistance, and installation parts you need to drive multiple zones, add subwoofers, and keep the music clear over engine and wind noise. Performance: 3,500-Watt peak / 880-Watts Dyno-Certified RMS total; 70-Watts x8 @ 4 Ohms, 110-Watts x8 @ 2 Ohms, or 220-Watts x4 bridged @ 4 Ohms. Independent 12 dB/oct HP/LP/full crossovers for CH1-4 and CH5-8 plus 0-12 dB bass EQ @ 45 Hz help you tune each zone. Durability: Conformal-coated PCBs, UV/salt-resistant finish, and stainless steel end caps, hardware, and bottom plate fight corrosion season after season; non-corrosive RCA inputs and bolt-down block terminals maintain secure connections. Connectivity: Bluetooth with auto pairing, RCA line out, 4CH/8CH input mode to use two RCA outputs for all eight channels; voltage display simplifies diagnostics; S/N >95 dB with <0.05% THD preserves detail. Installation: RWK42 supplies SuperFlex 4-AWG power/ground, two 17' 100% copper twisted-pair RCAs, 16-gauge speaker wire, 18-gauge remote, AGU fuse holder with 80-Amp fuse, split loom, ties, rings, spades, butt connectors, and grommets for a neat, serviceable run.Specifications: Frequency response 10Hz-30kHz; damping factor >150 @ 100Hz; channel separation >45 dB; input sensitivity 280 mV-7 V; chassis 6.7" W x 2" H x 10.8" L; color White. Ideal users: boat owners, installers, and marina shops needing multi-zone coverage with simple control. Competitive advantage: compact footprint, dual independent crossovers, genuine Dyno-Certified ratings, ABYC-conforming design, and a true 4-AWG kit that supports reliable, code-minded marine wiring.
