The CT Sounds ATv2-1400.1d monoblock class d car amplifier will deliver the power you need to destroy the competition in the SPL lanes. Rated at 13.2v, this monoblock amplifier will deliver over 1800 watts RMS power at 1 ohm. The car monoblock amplifier is strappable (slave/master switch) so that you can get more power output should your system require it.

Engineered to be the best in its class, the amplifier uses an advanced PCB board featuring Korean capacitors, MOSFET pulse width modulated power supply, high-quality transformers, and cutting-edge inductors. The amplifier comes equipped with a 4-way protection circuitry along with reverse polarity protection.

The plexiglass backing, illuminated LED CT Sounds logo, and white chassis give this amplifier an unbeatable appearance. Variable adjustment controls feature gains, subsonic, bass boost, low pass filter, and phase settings so you can get the exact sound you are looking for out of your amplifier. Included with the amplifier is the highly demanded AT Series On/Off Bass Knob which not only lets you adjust the bass boost but also displays your system voltage.
