Power - 3000 Max x 1 @ 1 Ohm, 1500 Max x 1 @ 2 Ohms, 750 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 EVO3000.1 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” Variable Subsonic Filter - To prevent your subwoofer(s) from bottoming out, the variable subsonic filter filters out frequencies below the subwoofer(s) specified low frequency limits and allows the driver to reach a maximum safe excursion Variable Bass Boost - Bass Boost allows you to adjust the low bass within the boost range to just the way you like it Specs - Dimensions: 12.69” x 10” x 2.3”, Weight: 8.81 lbs., Speaker Impedance: 1 to 8 Ohm, THD @ RMS Output: 0.01%, S/N Ratio: 100 dB, Frequency Response: 15 Hz to 500 Hz, Fuse Quantity: 3 35 ATO Blade Sound Storm Laboratories provides a 6 Year Platinum Online Dealer Warranty for purchases through Amazon.Com.
