What this mono amplifier delivers

The AudioControl LC-1.1500 is a single-channel subwoofer amplifier rated at 850 watts RMS at 4 ohms and 1500 watts RMS at 2 ohms. Class D circuitry keeps heat low while supplying continuous power to one subwoofer. It is intended for car-audio enthusiasts who want strong, clean bass from a dedicated mono block.

How the included controls shape the sound

AccuBASS circuitry restores low-frequency content that factory systems often attenuate. A variable low-pass filter adjustable from 30 to 230 Hz at 24 dB per octave lets you match the subwoofer to the rest of the system. A fixed 24 Hz subsonic filter protects the driver from infrasonic energy. MILC LED indicators show when input levels are optimised or clipping occurs.

Build practicalities for daily install

Preamp and speaker-level inputs accept signals from almost any head unit without extra converters. GTO signal-sensing turn-on activates the amp automatically when music plays through speaker-level inputs, removing the need for a remote lead. Four 40 A fuses protect the power stage. Wiring and mounting hardware are not supplied, and an optional wired remote level controller can be added for dash-mounted gain adjustment.

Questions about this item

Will the 40 A fuses need periodic replacement under normal use?

The four 40 A fuses protect the power supply; they only require replacement if a fault causes one to blow.

What limits continuous output during extended heavy bass passages?

Thermal protection engages once the Class D heatsink reaches its safe operating temperature, reducing output until the amp cools.

How much heat and fan noise should I expect when the amp runs all day?

Class D topology runs efficiently, so the heatsink stays warm rather than hot and there is no cooling fan to generate noise.
