From /products/buttkicker-bka-1000-n-audio-amplifier-1000w  :The ButtKicker BKA-1000-N 1000W Power Amplifier is designed specifically to power the ButtKicker Tactile Transducers. ButtKicker amplifiers feature a wider frequency response than your average subwoofer amplifier. The wider frequency response means your Tactile transducers will provide more punch down at very low 10Hz frequency which is where you want to be in a Home Theater environment. No preamplifier is required. For home theater, just use a RCA cable to go from your processor's subwoofer out* to the RCA input on the ButtKicker Amplifier. Then, use 12 gauge speaker wire from the amplifier to the ButtKicker. It's as simple as that, plug-n-play. With 1000 watts into 4 ohms and 1900 watts into 2 ohms. Not only does the ButtKicker Amplifier have over 1900 watts of power, it adds low and high cutoff filters at no additional cost. The BKA-1000-N is able to power up to 4 BK-LFE Transducers or 8 BK-Mini-LFE Transducers.Specifications:1000 Watts @ 4 ohms1900 Watts @ 2 ohmsPowers up to 4 BK-LFE Transducer (Series/Parallel Network 4 Ohm Load)Class D switching technologyVariable high cutoff, 40 to 160 HzLow cutoff, 25 Hz switchableRCA and ¼" inputs with 160mVolt and 1.25 Volt sensitivitiesFive way binding post speaker wire outputConvection cooling, i.e. no fan12"W x 11"L x 4.375"H,23 lbs. / 10.5 kgDo I dare open this?  I really don't want to...
