PDX-4.100 4/3/2 Channel Power Density Digital Amplifier
Good things come in small, stackable packages.
Who knew something so small could pump so much power? The Alpine
PDX series amplifiers are for the true car audio enthusiast – for
those who want the best power, sound quality, and efficiency, all
from a compact size. Get the most out of your system with Digital
PDX.
Accurate Dynamic Sound Reproduction
Alpine’s goal is to deliver the best sound quality possible. With
the PDX series, digital switch-mode amplification yields incredible
sound quality. Advances in the PDX design include improved feedback
circuitry to faithfully reproduce the input signal for improved
dynamic range and higher fidelity. If you’re listening to your favorite
rock song, your amp is ready to jump from loud to calm and back
again with ease.
By the Power Invested in PDX
We now pronounce you amplified. The PDX mono amplifiers can be used
with virtually any subwoofer(s). PDX amps produce the same amount
of power into both 2ohm and 4ohm so they will get the most from
your subwoofers in almost any situation.
Stack ‘Em Up
The PDX amplifiers all share a universal chassis size – all models
are the same size so you can vertically stack the set up you want.
Their unique design makes them easy to stack, easy to install. Plus,
the main controls are found behind the front panel of the amp, so
the amp always looks neat and tidy and easy to access.
Speaker Control
Let your amps control your speakers. The PDX amplifiers’ groundbreaking
damping factor means less distortion and clarity that exceeds other
amplifiers.
Less Load on your Alternator and Battery
Get the most out of your stereo system without a trailer load of
batteries. The PDX revolutionary design provides higher efficiency
at all volume levels.
Low Interference
Install these amps anywhere in your vehicle without interference.
So you can store an amp or few under your seat, and won’t have to
worry about interference coming from other electronics in your car
environment. Their small footprint and unique stacking capability
make them perfectly suited to the hash in-vehicle environment.
Make Use of your Space
Now you don’t have to sacrifice space in your car for big bulky
amps. PDX amplifiers are built from an advanced Power Density design
to provide more power per square inch. Stick to PDX to get the best
sound quality without taking up too much room.
