Compact Class D Bass Power with Precision Tuning

This mono subwoofer amplifier delivers strong low-end performance with 200W RMS at 4 Ohms and up to 300W RMS at 2 Ohms, making it perfect for powering a dedicated bass system. Its high-efficiency Class D design keeps output powerful while reducing heat for stable long-play performance. With an adjustable 20–500 Hz low-pass filter and a variable 10–500 Hz infrasonic filter, you get precise bass tuning, cleaner speaker blending, and added protection against damaging ultra-low frequencies.

Enhanced Bass Tuning with Rugged IP67 Durability

Dial in stronger low-end performance with a switchable 0°/180° phase control to reduce bass cancellation, plus an adjustable 0–18 dB bass boost at 37 Hz for added punch and depth. Built for extreme environments, its IP67 water and dust resistance makes it perfect for marine or off-road use, while the heavy-duty cast alloy chassis improves cooling and protects internal components for long-lasting reliability.

Flexible Installation with Reliable Performance & Warranty Support

Compatible with both RCA preamp and speaker-level inputs for easy integration with factory or aftermarket systems, this amplifier is designed for flexible installs in any setup. It supports recommended 8-gauge power and ground wiring with a 35-amp fuse for safe, stable operation, while its external fuse design keeps multi-amp installations clean and efficient. The slim chassis fits tight spaces with ease, and long-term confidence is backed by a 3-year warranty and 60-day return policy.
