Planet Audio PL4000.1D Pulse Series Class D Monoblock Car Amplifier – 4000 High Output, 1 Ohm Stable, Low Level Inputs, Low Pass Crossover, MOSFET, Hook Up to Subwoofer for Bass

Power - 4000 Max x 1 @1-Ohm, 2000 Max x 1 @2-Ohms, 1000 Max x 1 @4-Ohms, 8000 Max x 1 @2-Ohms strapped
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
Class D - Power loss is significantly reduced making the amplifier highly efficient. Excess energy is stored until it’s needed instead of being converted into heat. Reduction in size/weight, reduced power waste, smaller heat sink, compact 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 PL4000.1D amplifiers and double the power that is being sent to your subwoofers. You now have the ability to connect more subwoofers to take advantage of the extra power

Q: How many Ampere in 4500 Watt/Volt? The answer is 4,500. Others Electric Current converter. Convert: (Please enter a number)

Q: What is a Class D amplifier?

A: Frequently referred to as a digital amplifier, the class-D amplifier is an electronic device that increases the size of electrical signals. What distinguishes the class-D amplifier from other types of amplifiers is its design, which trades off the risk of increased distortion for a very high level of efficiency,…

Q: How do you calculate wattage?

A: Calculating Wattage. The formula for calculating wattage is: W (joules per second) = V (joules per coulomb) x A (coulombs per second) where W is watts, V is volts, and A is amperes of current. In practical terms, wattage is the power produced or used per second.

Q: What is a home stereo amplifier?

A: The function of a home stereo amplifier is to power the speakers connected to it, and some amplifiers are included in a receiver, which is a unit that powers the speakers and picks up radio signals for transmittal. A receiver can also control the audio mix as well as the power output, speaker selection, and so on.
