Sound Storm Laboratories EVO4000.1 Evolution Series Car Audio Amplifier - 4000 High Output, Class D, Monoblock, 1 Ohm, Mosfet Power, Low Level Inputs, Low Pass Crossover, Hook to Stereo and Subwoofer

Power - 4000 Max x 1 @ 1 Ohm, 2000 Max x 1 @ 2 Ohms, 1000 Max x 1 @ 4 Ohms 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 EVO4000.1 amplifiers and double the power that is being sent to your subwoofer(s). You now have the ability to connect more subwoofers to take advantage of the extra power Phase Control - Phase control lets you adjust the speaker phase with the amplifier if your speakers or subwoofer are hooked up “out of phase”
