    Class D Mono 5000W Amplifier

    Number of channels:

    1 / Mono Block

    Max power output: 5000 Watts / Linked = 10000 Watts

    RMS power 2-ohm: 3000 Watts / Linked = 6000 Watts

    Class: "J" Digital

    Speaker connection: 8-Gauge

    Recommended power connection: 0-Gauge

    Dimension: 2.375" x 10.125" x 16.5"



    4000 Wrms @ 1 ohm

    DIMENSIONS ( L x W x H ) 13.375 x 11.5 x 2.125

    What does it take to create an HD4000?

    First we started out with a total redesign of the Class D input section. We gave the amp a 150 volt rail as opposed to our standard 80 volt rail. But, simply raising the rail voltage is not enough. The switching of the power supply had to be adjusted as well as the protection circuit and transformer ratios. The output section also needed to be beefed up with higher voltage/amperage MOSFETS to handle the substantial increase in power.

    The results:

    4000 watts of Pure Sine Wave POWER from only 13.8 volts of battery power and an Efficiency of 76% at full power! This level of efficiency is a HUGE factor because many of the street classes limit the amount of batteries you can have or add to your system.

    Big power in a single chassis! You don’t need to “stack” amplifiers to get the power you need. The HD4000 measures only 13 Inches in length; not much bigger than a sheet of paper… Absolutely the smallest amplifier on the market producing 4,000 Wrms at 13.8 Volts.
