The PM600X4 is a 600 Watt 4-channel amplifier with high dynamic power using Class-a/b technology and a conformal coated pc board designed for motorsport and marine applications.

The TM400X4ad is a powerful and compact 400 Watt 4-channel amplifier.  The amplifier features our proprietary high efficiency Class-ad topology for maximum power, sound quality and efficiency in full-range amplifier. It also integrates our patented Constant Power technology which results in up to 25% more output power. Top mounted controls feature our patented C.L.E.A.N. circuit to easily set your gains, integrated low-pass crossover, and our famous Punch EQ.
 
The amplifier also features high and low level inputs combined with our differential inputs to eliminate incoming noise.  It can also provide a remote-out trigger when using high level inputs. Dual fan cooling, real time thermal monitoring and dual extruded heat sinks maintain heat dissipation even at high outputs keep the amp cool.
 
In addition to the conformal coated pc boards, the Element Ready™ design ads protection against water, dust and UV rays, making it great for multiple applications where it could be exposed to harsh outdoor environment.
