Skar Audio RP-350.1D Monoblock Class D MOSFET Amplifier — 350W RMS at 1 Ohm

Powerful, Compact, and Ready for Real-World Subwoofer Punch

The Skar Audio RP-350.1D is a dedicated monoblock amplifier designed to deliver clean, high‑output power in a compact footprint. Engineered for efficiency, this Class D MOSFET device checks the box for reliable performance in tight spaces without sacrificing headroom. It is conservatively rated at 350 watts RMS into a 1 ohm load, with a peak potential that can approach 388 watts under demanding conditions. This combination makes it an attractive option for those who want confident subwoofer control in smaller enclosures or trunks.

With 8 gauge power and ground terminals, the RP-350.1D is built to handle larger currents, which helps maintain strong bass response even at higher listening levels. The included remote subwoofer level control puts bass tuning at your fingertips from the front seat, allowing quick adjustments to match music, mood, or listening volume. The built‑in bass EQ switch gives you a choice of +6 or +12 dB boost at 45 Hz, enabling you to tailor the boom to your vehicle, subwoofers, and personal taste.

Designed for Performance and Protection

Designed around a robust heatsink and a well‑thought PCB layout, this amp aims to stay cool and responsive during long listening sessions. Its 4‑way protection circuit guards against common threats such as short circuits, overheating, and voltage fluctuations, helping to preserve the amplifier and your speakers over time.
