Alpine PDX-1.600 Mono 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.
The PDX amplifiers’ unique design allow for a clean, easy, and fast install in your car! All the controls and wiring connections are in one convenient location.
PDX amplifiers are 60% smaller than previous models with the same output power. Install your amps easily without sacrificing valuable room, power and performance.
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 in the trunk or under a seat.
Low Resistance, High Current Speaker Terminals
Quick disconnect plugs with low resistance and high current capabilities make installing quick and easy.
More Power, Better Sound
PDX amplifiers deliver outstanding sound quality. The revolutionary design of the PDX incorporates improved feedback circuitry and power supply filtering system, plus a damping factor that is 350% better than Class A/B amps.
Unprecedented Sound Matching & Accuracy
A highly effective Powerful Feedback Circuit accurately compares the amplifier’s 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.
Same Power Output - 2Ω or 4Ω Configuration
PDX amplifiers have the unique capability to deliver the same power output regardless of 2Ω and 4Ω loads. This provides the ultimate in system flexibility and subwoofer configuration diversity.
Power On Demand*
A combination of an advanced power supply, Class-D design, and switch-mode digital amplification allow PDX amplifiers to stay extremely efficient at all power levels. This produces less heat, eliminating the need for large heat sinks, just another reason why they can be much more compact than conventional amps.
The PDX amplifiers use Direct FETs device to make switch-mode digital possible. Direct FETs are very small output devices that take up less room and they switch on and off extremely fast when needed. Their ultra high-speed switching capabilities allow them to perform at frequencies that other Class-D amplifiers struggle to reproduce. This provides control over power consumption, and cooler operation.
*Full Range PDX Amplifiers Only (PDX-4.150, PDX-4.100, PDX-2.150 & PDX-5)
Pros: 600w Min. RMS @ 2 OR 4 Ohms, stackable amp (with the PDX4.100, PDX1.1000, or PDX-5?), extremely small size
Cons: Amp gets hot with regular usage, definitely keep this guy out in the open when possible!
Comments: These amps are amazing to say the least. You probably will find many stores with closeout pricing (I've seen at Best Buy so far) and at a price you can't beat. Runs great, plenty of power for what most of us will need, and super nice for tight spaces. Watch the heat, but I doubt it'll be an issue for most of us. I run long 6+ hour trips and at the end the amp feels a bit hotter than I feel it should. But, I have yet to have the amp go into protect or shut down due to thermal issues. Solid amps, highly recommended. My price paid is the RETAIL for the 1.600, but you'll likely see MUCH better pricing than that. I know I did!
Pros: Smaller size can fit anywhere. looks cool and delivers great power.
Cons: can't think of any
Comments: This thing is great. What did you expect from Alpine? Delivers power the same as bigger amps if not more. It's smaller size is great. I can mount it under my seat or the passenger seat instead of the back and sacrificing cargo space. It looks cool and it's a great addition the rest of my alpine system. Alpine is the only way to go.
