The Sundown Audio SIA-3500D V2 Mono Amplifier paired with the RWK0CU 0 AWG OFC Wiring Kit provides dependable high-output performance and installation components for serious car audio systems. This bundle is built for enthusiasts who require strong, stable bass output along with efficient power transfer and clean signal flow.
The SIA-3500D V2 features an intelligent full-bridge mono design capable of producing 3,500-Watts RMS @ 1-Ohm, 3,300-Watts RMS @ 2-Ohms, and 2,600-Watts RMS @ 4-Ohms. With a 108dB signal-to-noise ratio and operating voltage range of 10.5V–15.5V DC, it maintains clean and controlled output even during extended high-power sessions. Adjustable 12dB low pass filtering from 40Hz–20kHz, high pass filtering from 10Hz–1kHz, subsonic filtering, and 12dB bass boost @ 50Hz allow precise system tuning.
Thermal stability is supported by a heavy-duty aluminum heatsink and advanced 3-speed Smart Cooling fan system. Integrated thermal, voltage, speaker short, and DC-offset protection circuits safeguard both amplifier and speakers. A wired remote with clipping indicator allows accurate monitoring and adjustment from the driver's seat.
The RWK0CU installation kit complements this amplifier with true-spec 100% silver-tinned oxygen-free copper 0 AWG power and ground cables featuring a 4704 strand count for maximum current flow. The kit includes triple-shielded twisted pair RCA cables for interference reduction, 12-gauge flat speaker wire for high-power signal transfer, a gold-plated ANL fuse holder with 250A fuse, and nickel-plated terminals for secure connections.
Ideal for high-output subwoofer builds and daily-driven bass systems, this bundle delivers reliable power, efficient cooling, and quality installation for demanding car audio setups.
