Planet Audio PL4000.1D Pulse Series Monoblock Car Amplifier — Class D MOSFET, 4000 Max x 1 @1-Ohm

Overview: The Planet Audio PL4000.1D Pulse Series is a monoblock car amplifier designed to deliver powerful, efficient bass with modern Class D topology and a MOSFET power supply. Power Output: 4000 Max x 1 @1-Ohm; 2000 Max x 1 @2-Ohms; 1000 Max x 1 @4-Ohms. When two units are strapped the amp delivers 8000 Max x 1 @2-Ohms. MOSFET Power Supply: A MOSFET functions as an electronic switch that controls current flow. This design allows precise regulation of output voltage and current by removing output current sensing loss and eliminating secondary feedback circuitry. Class D Efficiency: The Class D architecture greatly reduces power loss, increasing efficiency. Instead of dissipating excess energy as heat, it stores and uses that energy when needed, resulting in lower power waste, reduced size and weight, a smaller heat sink, and more compact circuitry. 1 Ohm Stable: Built to continuously drive 1 Ohm loads without overheating or strain, making it well suited for demanding subwoofers that require higher current to perform as intended. Strapping Capable: You can strap two PL4000.1D amplifiers together to double output power, enabling you to power additional subwoofers and achieve higher overall SPL.
