The MTX Thunder4250D mono subwoofer amplifier uses a "pure N-channel" design with a MOSFET power supply for outstanding efficiency — turning most of the available energy into usable wattage rather than heat. MTX's Adaptive Class D Technology preserves Class D's cool-running efficiency, while improving the signal-to-noise ratio of this amp design.
