Mono Power Density Digital Amplifier - PDX-M6

Meet the New Amplifier Benchmark
The new Alpine PDX Series amplifiers are completely re-engineered for performance, sound quality, and reliability. The PDX series are for the true car audio enthusiast, all from a compact size. Consider the bar raised.

Product information

New Reference Grade Output Stage

 

Ultra-Wide Frequency Response

This super-wide, industry leading frequency range offers listeners unparallel sound quality and detail that bests even the most high-end audiophile equipment. 5Hz-100kHz for 4ch, 5Hz-400Hz for Mono (+0,-3dB)

Total Harmonic Distortion Rate (THD) vs. Frequency

The all-new PDX series amplifiers are not your typical class-D amplifiers. Traditionally, class-D amplifiers have not been known for high frequency reproduction. These new PDX amplifiers are the first ever class-D amplifiers to break tradition and trump the amps of yesterday. The PDX-M12, PDX-M6, PDX-F6, and PDX-F4 are synonymous with extremely high frequency reproduction. The THD is actually falling at high frequencies, resulting in a clean and clear signal where your ear is most sensitive to distortions. -<0.005% THD+N @ 1W, <0.05% THD+N @ rated power.

Signal to Noise

These amps are capable of unheard of S/N ratio up to 95dB S/N @ 1W, 122dB S/N at rated power for extremely clean, uncolored sound. Forget unwanted background noise or static. The PDX amps deliver crystal clear music every time.

Damping Factor

With ultra-low output impedance, the new PDX offers extremely controlled, tight bass for unprecedented sound quality. Ratings are >1000 for Mono and >500 for 4ch.

Power Output to the Extreme

 

Beefed up Power

The PDX power supply delivers tremendous headroom with low distortion and noise. PDX amplifiers have an extremely high total system efficiency of ~80% (power supply is rated at >90%, output stage is rated >90%).

Power Management Processor

PDX amps incorporate Alpine’s new Power Management circuit. The Power Management Processor controls all aspects of amplifier performance, monitoring voltage, temperature and output to ensure uninterrupted power output for non-stop listening. If the amp gets too hot, the Thermal Protection circuit kicks in and gradually decreases output power until it cools down. Once cool, the power output automatically increases back to the previous level. If the circuit detects a Low Battery condition, it will gradually decrease power output if battery voltage becomes too low. Once the battery voltage increases, power will be restored. This interruption-free design allows for non-stop enjoyment with no hiccups or drop-outs, just clean, clear output.

Low Impedance Stability

These amps are stable at low impedances and are capable of their rated power from 2 to 4 ohms for all models. This allows excellent flexibility with multiple speaker and subwoofer loads and is adjusted automatically.

Certified Power From Birth, Guaranteed.

Each PDX amplifier comes with its very own birth-sheet. PDX amplifiers are tested and documented to show their true actual output.

Application Flexibility

 

Unique Stacking System

The new PDX series amplifiers are 20% thinner than previous models at only 2” thick. New stacking system packs the amps closer together so there are no gaps and to save space in the trunk while directly coupling the amps heatsinks to help share cooling duties.

Speaker terminals

The super high power speaker connectors allow for up to 10 mm² wiring and have a unique quick disconnect design for simple error-free installation.

Power Connector

The new removable connector features a low-loss, high-current design. It accepts up to 25 mm² wire, to ensure your amp gets the power it needs while allowing for easy installation.

Remote Control Bass Knob (RUX-KNOB)

Simply add the RUX-KNOB (sold separately) and get full control from inside the dash for remote on-the-fly bass adjustments. You also have the ability to control multiple amps from just one controller with simple telephone cord adapters.

A Touch of Personalization

PDX amplifiers come with easy-to-remove trim rings, so if you would like to customize them, you can have them painted. Add it as another Do-It-Yourself project, or leave it to professionals and ask an Authorized Alpine installer near you. The removable trim ring can be custom painted to match your vehicle or personalized to anything you want.
