The RAM Audio XTR Series has been designed with the aim of offering the proper and more reliable amp to users of very big subwoofers with no concessions. Their output performances (270V/70A) are more than needed to push your subs as far as their maximum limits accept.

These 2-channels devices are based on the field proven Quanta PulseTM Technology with an oversized dual high capacity regulated power supply with PFC to deliver their full performances independently of mains status, and an also oversized high efficiency audio power stage, forced front to back cooling through a component-free path with removable front panel dust filters, improved rugged mechanical design with even weight distribution.

In short… with XTR amplifiers you make sure that you will get the maximum output performances to your more powerful subwoofers without compromises!
