AudioControl LC-1.1500 High-Power Mono Subwoofer Amplifier with AccuBASS® – 1500W RMS
Product Description
Experience powerful, deep and controlled bass with the AudioControl LC-1.1500 High-Power Mono Subwoofer Amplifier. Designed for serious car audio enthusiasts, this high-performance monoblock amplifier combines impressive output power with advanced signal processing and flexible factory audio integration.
Delivering 850W RMS at 4 ohms and an incredible 1500W RMS at 2 ohms, the LC-1.1500 provides the power needed to drive demanding subwoofer systems with authority.
One of its standout features is AudioControl's patented AccuBASS® technology, designed to compensate for factory-installed audio systems that reduce bass output as the volume increases. This helps restore low-frequency performance and maintain fuller, more consistent bass.
The LC-1.1500 also features MILC™ Maximum Input Level Control and GTO™ Signal Sense, helping simplify integration with compatible factory head units. Its speaker-level and balanced RCA inputs provide flexible connection options for both OEM and aftermarket audio systems.
With an adjustable 24dB/octave Linkwitz-Riley low-pass crossover, a 24Hz PFM subsonic filter and compatibility with the optional ACR-1 remote control, the LC-1.1500 offers extensive control over your subwoofer setup.
Housed in a solid one-piece aluminium chassis, this amplifier is built for high-power installations where performance, reliability and sound quality matter.

AccuBASS® – Restore Your Factory Bass
Many factory-installed car audio systems reduce low-frequency output as the volume increases to protect their original speakers.
AudioControl's patented AccuBASS® processing is designed to compensate for this factory bass roll-off, helping restore bass performance and deliver a fuller listening experience.
This makes the LC-1.1500 particularly suitable for powerful subwoofer upgrades while retaining a compatible factory head unit.
Advanced OEM Integration
The LC-1.1500 is designed to integrate with both factory and aftermarket audio systems.
Speaker-Level Inputs: Connect directly to compatible factory speaker outputs.
Balanced RCA Inputs: Connect to an aftermarket head unit or compatible audio processor.
MILC™ Technology: Helps manage incoming factory audio signals to maintain appropriate input levels.
GTO™ Signal Sense: Automatically switches on the amplifier when an audio signal is detected in supported installations.
Subwoofer Control & Performance
The adjustable Linkwitz-Riley low-pass crossover allows you to select a suitable frequency between 30Hz and 230Hz, helping match the amplifier to your subwoofer system.
The built-in 24Hz PFM subsonic filter provides additional protection against unwanted ultra-low-frequency signals.
For convenient bass adjustment, the LC-1.1500 supports the optional AudioControl ACR-1 remote level control.
