The tough-looking Profile Clarus CL600M mono amplifier makes the perfect engine for your subwoofer setup! The lightning-fast MOSFET power supply gives you all the juice you need.

A built-in low-pass crossover and a switchable subsonic filter (off/20/50 Hz) let you tune your sound for maximum slam. And when you need just a bit more oomph, you can engage the 0-18 dB bass boost, centered at 45 Hz.

Speaker-level inputs and preamp outputs simplify connection and multi-amp system expansion. The CL600M will readily accept up to 4-gauge power and ground wires, and up to 6-gauge speaker wires.
