AR4000D Class D Monoblock Car Amplifier - 4000 High Output, 1 Ohm, Low Level Inputs, Low Pass Crossover, MOSFET, Bass for Subwoofer

Power - 4000 Watts Max x 1 @1-Ohm, 2000 Watts Max x 1 @2-Ohms Class D - Power loss is greatly minimized, making the amplifier highly effective. Excess energy is stored until required instead of being turned into heat. Reduced size/weight, lower power waste, smaller heat sink, compact circuitry. 1 Ohm Stable - Capable of continuously powering loads of 1 Ohm without facing issues such as overheating. Typically built to power subwoofers that need the heavier power load requirements to perform as intended. Strapping Capable - You can strap two AR4000D amplifiers and double the power delivered to your subwoofer (s).

You now have the ability to connect more subwoofers to utilize the extra power. Variable Bass Boost - Bass Boost lets you adjust the low bass within the boost range to exactly how you like it. Variable Subsonic Filter - To prevent your subwoofer (s) from bottoming out, the variable subsonic filter removes frequencies below the subwoofer (s) specified low frequency limits and allows the driver to reach a maximum safe excursion. Variable Low-Pass Crossover - Subwoofers reproduce sound based on a number of different low-range frequencies. You can set precise sound specifications for the bass frequency reproduction.

Specs - Dimensions: 14.3" x 6.5" x 2.8", Weight: 7.96 lbs
