The Pyle Academy series is an affordable option to provide high-power, high-quality sound to your vehicle's speakers. Academy amplifiers are sturdy with amp heat sinks and accept both low level RCA inputs as well as high-level, low-impedance MOLEX inputs. And our D-series feature Class-D digital amplifiers, which greatly reduce power consumption and heat while increasing sound levels for an overall major boost in efficiency. The PLAM2001D is a 2000-watt class-D monoblock amplifier. It's equipped with variable gain control, a built-in variable subwoofer crossover, and a three-way configuration. Silver RCA inputs ensure your sound is insulated from the harsh electromagnetic environment. The MOSFET pulse width modulation power supply allows for a clean, distortion-free signal to your speakers. To keep both your car and the amplifier safe, this model is equipped with thermal, overload, and short circuit protection. Welcome to the academy - the Pyle Academy.
