The CXA800.1 is a CX-Series mono Class-D amplifier designed to drive subwoofers with up to 800 watts into one bass channel and is stable down to 1 ohm. It features KickEQ variable bass boost for up to 6 dB of extra low-end when paired with the optional CXARC Remote Bass Controller, plus a 12 dB crossover and a 24 dB subsonic filter for precise tuning.

The amp accepts speaker-level input up to 40 volts (400 watts) to eliminate the need for line-output converters and includes full-range RCA pass-through outputs to expand or chain additional amplifiers. It ships with hardware for standard or vertical mounting to suit different installation orientations.
