Alpine PDX-M6 600 Watt Power Density Digital Subwoofer Amplifier

The new Alpine PDX-M6 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.

Noteworthy Honors Award

Design and engineering showcase honors in 2010

The Alpine PDX Series is a recipient of the 2010 CES Innovations honors award. Every year at the world’s largest consumer technology tradeshow, the Consumer Electronics Show (CES), the Innovations Designs and Engineering Awards program recognizes the most innovative consumer electronics products, such as the PDX Series for the In-Vehicle Audio category.

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(THD+N) vs. Power

The all-new Alpine PDX-M6 amplifiers are not your typical class-D amplifiers. Traditionally, class-D amplifiers have not been known for both low distortion and wide frequency response. 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 resolution and detail.

Total Harmonic Distortion(THD+N) vs. Frequency

Uniquely The Alpine PDX-M6, distortion actually decreases at higher frequencies, resulting in a clean and clear signal where your ear is most sensitive to distortion. -<0.005% THD+N @ 1W, <0.05% THD+N @ rated power.

Frequency Chart

Signal to Noise

These amps are capable of unheard of S/N ratios 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 Alpine PDX-M6 offers extremely controlled, tight bass for unprecedented sound quality. Ratings are >1000 for Mono and >500 for 4ch.

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%).

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.

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.

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 8GA 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 4GA 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 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 removable trim rings, allowing them to be easily custom painted to match your vehicle or personalized to anything you want. Add it as another Do-It-Yourself project, or leave it to professionals and ask an Authorized Alpine retailer/installer near you.


Alpine X-W12D4 X-Series 12″ Dual 4-omh Subwoofer

The Alpine X-W12D4 12″ subwoofer handles up to 900 watts RMS, so don’t hesitate to give it plenty of juice. This rugged sub features a pulp/mica cone with a parabolic shape that maintains its rigidity and strength for outstanding response and accuracy. The big rubber surround supports the cone in the sub’s cast aluminum frame, while Alpine’s latest technology allows this sub to move an amazing amount of air (28mm Xmax, for you bass geeks out there) at very high levels while staying cool.

You can wire the dual 4-ohm voice coils to get the optimum performance from your amp, or to configure a custom setup with multiple subwoofers. The Alpine X-W12D4 works well in sealed and ported enclosures so you can choose what kind of bass you want to hear and feel.
