Here are the results of preliminary testing of the 'infamous' Buttkicker amplifier. It would not even come close to rated specifications. On the other hand, the specifications are rather limited. Here they are directly from the website.
"ButtKicker Amplifier Specifications
Model #: BKA1000-4A
1000 Watts @ 4 ohms
1900 Watts @ 2 ohms - will power 2 ButtKicker LFEs wired in parallel , and 4 ButtKicker LFEs used in individual home theater seats.
Class D switching technology
Variable high cutoff, 40 to 160 Hz
Low cutoff, 25 Hz switchable
RCA and ¼ inputs with 160mVolt and 1.25 Volt sensitivities eliminates the need for a separate pre-amplifier
Five way binding post output
120v or 240v versions available
Convection cooling, i.e. no fan
12"W x 11"L x 4.375"H,
11 lbs / 11.36 kg"
No S/N, distortion, frequency response, etc. is given at all. Here are the preliminary results of testing at 4 ohms. It doesn't look good for 2 ohms. Power is down, distortion is up, and frequency response, well, you get the picture.
I will post more tomorrow.
