Power - 4000 Max x 1 @1 Ohm, 2000 Max x 1 @2 Ohms, 1000 x 1 @4 Ohms, 8000 x 1 @2 Ohms Strapped
Class D - Power loss is significantly reduced making the amplifier highly efficient. Excess energy is stored until its needed instead of being converted into heat. Reduction in size/weight, reduced power waste, smaller heat sink, compact circuitry
MOSFET Power Supply - A MOSFET is an electrical switch that allows the flow of electrical current. It controls the output voltage and current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry
1 Ohm Stable - Able to continuously power loads of 1 Ohm without encountering difficulties such as overheating. Typically made to power up subwoofers that demand the heavier power load requirements to be able to perform the way they were made to
Strapping Capable - You are able to strap two TR4000.1D amplifiers and double the power that is being sent to your subwoofer(s). You now have the ability to
