Want an amplifier that is built to last? Go for Diamond Audio D1000.1 1100 Watt 1-Channel Amplifier. The Diamond D1000.1 mono sub amplifier sends up to 1100 watts RMS of clean, pure musical power to your subwoofer, with no audible colouration or distortion. This mono powerhouse loves a 1-ohm load, so it will work well in a wide variety of sub systems. The D1000.1 can be strapped with a second D1000.1 to achieve a respectable 2200 watts RMS at 2 ohms. The focussed mass heatsink draws heat away efficiently by attaching 75% of its mass directly to the components that create the most heat. The amplifier's output transistors also mount to the heatsink using a special system that provides better heat flow than commonly used clips. The D1000.1 features variable low-pass and subsonic filters, a bass boost, and a phase switch so you can focus all that power to make your sub system sound its best. A pair of preamp outputs makes it easier to add more amplifiers when you want, without having to run a new RCA cable to the receiver. The D1000.1 comes with a remote level controller, so you can adjust the amount of bass on each song from the front seat.
