- Package Includes: (1) Rockville ATOM S20 Marine Bluetooth Amplifier 1600w 4 Channel/Volt Meter+PA Mic; (1) Rockville RMWK4 4 AWG Gauge Waterproof Marine Amplifier/Amp Install Wire Kit; (1) Rockville MRCA25 25 Foot Twisted Pair Marine RCA Cable 100% Copper, Split Pin
- Marine-Ready Power And Control: Rockville ATOM S20 packs Class-AB punch with Dyno-Certified 440-Watts RMS (110x4 @ 2-Ohm; 70x4 @ 4-Ohm; 220x2 bridged @ 4-Ohm), Bluetooth audio, a digital volt meter, and an included PA mic for clear onboard announcements. Dual 12 dB/oct HPF/LPF (50-250 Hz) on both channel pairs plus 2CH/4CH input mode let you fine-tune zones, run speakers or subs, and keep rigs compact with its rustproof stainless chassis and conformal-coated PCB.
- Clean, Reliable Wiring: The RMWK4 4-AWG marine kit is purpose-built for harsh environments with flexible, chemical-resistant jackets, a sealed mini-ANL fuse holder, and high-current, low-impedance power and ground runs for stable voltage delivery. Included remote turn-on and speaker leads support neat, labeled runs from helm to transom, helping prevent voltage drop, reduce heat at terminals, and deliver consistent performance during long cruises or high-volume sessions.
- Noise-Free Signal Path: MRCA25 premium 25-ft twisted-pair interconnect uses tinned copper conductors, polyethylene dielectrics, and waterproof split-pin plugs to lock in tight, corrosion-resistant connections. The construction improves common-mode noise rejection to fight alternator whine and RF interference, preserving detail, stereo imaging, and low-frequency weight-so wireless streaming through ATOM S20 stays clear from idle to wide-open throttle across open water.
- Flexible System Design: ATOM S20 drives up to eight cabin or tower speakers, a pair of subs (bridged), or mixed zones with independent crossovers on each channel pair for precise tuning. Adjustable input level, 12 dB bass EQ, RCA line out, and protective undervoltage/overvoltage circuits simplify expansion and safeguard gear. Pair with the RMWK4 and MRCA25 to build a dependable, serviceable marine system for cruisers, pontoons, and wake/surf boats.
