4 Channel Power Amplifier


Our Epicenter Amplifier is a BEAST! While prototyping new amplifiers, our tech, Jim, insisted that we offer this amplifier. He fought tooth and nail to bring this amplifier to life and add it to the Seismic Audio line up. He has been doing audio for 30 plus years and said it was the best bang for the buck he had seen in all his years. And he owns a TON of audio gear by brands you didn't even know existed and those you see in all the big box speaker stores as well.


Our 4 Channel Amps give you access to 4 channels while only taking up 2 Rack Spaces in your Rack Case and does not sacrifice power by doing so! This is a 4 channel amplifier capable of pushing just about anything. This is a high end amplifier that is rack mountable and has a Frequency Response of 5Hz to 50kHz. These are by far the best bang for your buck in the industry! These amps are easily capable of pushing eight 18" Subwoofer Cabinets or two pairs of Dual 15" Speakers. You can run your subs, monitors, and mains from one amplifier and consolidate your gear. Do a Google search for "Pro Audio 4 Channel Amplifiers".
