Pyramid® - America Class AB 2-Channel Bridgeable 5000W Mosfet Amplifier
It's good for the money you pay. I have a Lanzar 12" 6000 watt peak 3000 watt rms with dual voice coils and it bumps it pretty hard but no where near close to its potential. Then again my sub cost three times as much as the amp lol. The protect comes on and you have to completely power down your head unit for it to go off, rather than turning it down and waiting a minute for it the amp to kick back on. I'd almost rather put this amp on some bada** door speakers. Bottom line you get what you paid for.
