Full Range Class D Digital Monoblock Amplifier — 8000 W RMS

The Concrete Audio CA8000-1SLM is a high-power Class D digital monoblock amplifier engineered for massive output and refined control in custom audio systems. Designed to stay stable under heavy load and deliver clean, dynamic power, this amplifier is ideal for high-output subwoofer, pro audio systems and serious performance builds. 

With power ratings that include 8000 W RMS at one ohm, 4300 W RMS at two ohm, and 2090 W RMS at four ohm, the CA8000-1SLM provides flexibility for a wide range of configurations while maintaining solid performance across the frequency spectrum. Its 10 Hz-20 kHz frequency response and signal-to-noise ratio greater than 90 dB ensure dynamic power delivery with minimal distortion.

Tuning options — including an adjustable low-pass crossover (50 Hz–20 kHz), subsonic filter (15 Hz–5 kHz), and a 0–12 dB bass boost (30 Hz–70 Hz) — give you precise control over your system’s low-end response. Built-in protections for thermal, overload, short-circuit, and voltage help keep your system safe under demanding conditions, while included remote level control simplifies adjustment from the driver’s seat.

Whether you’re pushing for competition-level SPL or building a high-output daily driver system, the CA8000-1SLM brings serious power and refined tuning to any custom audio install.
