Alpine's new PDR series amplifiers

"Brand New PDR Amplifiers from Alpine Electronics Endure Legacy of Compact Amplifiers with Powerful Output"

"Key features of the new PDR amplifiers include:

Quiet Performance: The ultra-low signal to noise ratio provides clearer music without background hiss.
Power Density: The PDR amplifiers are small and easy-to-install, with big power output.
Quality Bass Performance: Ultra-high damping factor keeps bass clean and tight.
Power Verification Certificate: Every PDR amplifier comes with a “Birth Sheet” indicating the actual measured power of the amplifier.
Easy-to-Adjust Bass: The mono PDR-M65 and 5-channel PDR-V75 are compatible with the optional RUX-KNOB remote bass knob for easy bass adjustment from the dash.
Rotatable Alpine Badge: The Alpine badge can be installed in four different orientations so it is straight no matter what position the amplifier is installed.
Thermal Performance Stability: The higher efficiency design allows for improved thermal management, to help sustain output power and prevent shutdown of the amplifier.
Dual Feedback Modulation: Dual internal error correction technology, which is incorporated in other Alpine amplifiers, is adopted in the PDR-M65 mono amplifier.
2- or 4-channel Speaker Input and Pre-Outs: The PDR-M65 mono amplifier can connect to a factory head unit via speaker-level inputs (up to 10V), making it ideal for an easy factory system upgrade.
Remote Sensing: The amplifiers automatically turn on when voltage is detected on speaker-level inputs, eliminating the need to run a separate amplifier turn-on wire when upgrading factory systems."

Oh I did steal the info from an article about the release... oops...

You can defiantly notice the wear on these from the two prior days at the show as well as the press conference a week earlier.
