SPL3800.1 - 3800 Watt Mono Class-D Amplifier

The SPL3800.1 is a competition-grade Class D monoblock built for high-demand subwoofer applications where power density and control matter. Rated at 3800W RMS into 1 ohm, it supports strapped operation for installers who need to push the limits further. A microprocessor-controlled fan and four-way protection circuit keep it stable under sustained competition loads.

• 3800W RMS @ 1 Ohm (14.4V) — scales to 2600W @ 2Ω and 1400W @ 4Ω for flexible system matching
• Strapped Mode — bridges two SPL3800.1 units for doubled output in competition builds
• Remote Bass Boost — 0–16dB range with voltage display on the wired remote for real-time monitoring
• HPF/LPF Crossover — low-pass filter adjustable from 35Hz–258Hz; subsonic filter covers 12Hz–48Hz
• Microprocessor-Controlled Fan Cooling — regulated cooling responds to thermal load rather than running at fixed speed
• 4-Way Protection — guards against thermal overload, overvoltage, speaker short, and DC offset
• Low THD+N — less than 0.09% at 1W with a 95dB signal-to-noise ratio
