Smart Stacking
The PDX amplifiers feature a smart stackable design. All PDX amplifiers are the same size, regardless of the amount of power or channel specifications. Their exclusive design allows them to be stacked vertically on top of one another. This is an industry-first installation option that saves a ton of space.

Unprecendeted Sound Matching Accuracy
A highly effective Powerful Feedback Circuit accurately compares the amplifiers output against the original music signal. If there are any differences found between the two, the feedback circuit automatically removes the distortion in real-time! This keeps your music true to the original recording without added distortion or filter noise.
