Show original supplier description
The CT Sounds ATv2-1400.1d monoblock car amplifier is engineered to deliver exceptional power for competitive SPL (Sound Pressure Level) applications. It provides a robust 1400 watts RMS at 1 ohm with a 13.2v system, and can push up to 1800 watts RMS at 1 ohm when operating at 14.4v, offering significant output for demanding subwoofers. This amplifier boasts a unique strappable feature with a slave/master switch, enabling users to connect two ATv2-1400.1d units. This configuration doubles the power output at 2 ohms, providing a substantial 3600 watts RMS for extreme audio systems. Customization is key with the ATv2-1400.1d's variable adjustment controls, including continuously-variable input gain, subsonic filter (10 Hz - 50 Hz), bass boost (0 dB - +18 dB at 50 Hz), low-pass filter (35 Hz - 250 Hz), and phase adjustment (0° - 180°). The included AT Series Bass Knob offers remote gain control, a clip light indicator, a built-in voltmeter, and a pushable on/off switch, allowing for on-the-fly adjustments and system monitoring. Beyond its performance, the amplifier features an eye-catching design with a plexiglass backing, an illuminated blue LED CT Sounds logo, and a white chassis. It also includes a remote turn-on/turn-off circuit that can be controlled by the head unit or the bass knob, with a default setting to turn off with the vehicle.
