Sometimes size doesn't matter. Alpine packs Class-D amplifier technology into their PDX amplifiers for awesome power from a compact frame. These small-but-mighty amps free up valuable space and run so cool they can be stacked together for a sweet multi-amp setup.

The PDX-4.150 4-channel amplifier supplies 150 watts of full-range power to each channel, plenty of power for the most demanding component speaker systems or most subs. Beefy internal components and clever engineering keep the power output strong and the noise low for superb fidelity and control. Adjustable frequency filters tailor the amp's output to your specific system.

Front-mounted controls make post-installation adjustments a snap. Gold-plated RCA inputs and power connections resist corrosion and signal degradation. Nifty speaker wire plugs ensure a tight connection and guarantee that your speakers work in unison.

LOVE IT!!!!!!! May-11-09
Reviewer: bigredishott from Springfield, MA  
I bought this amp to replace a Alpine MRV-F345, and to power a set of Infinity Kappa Perfects 6.1 and Infinity Ref. 9622i. It is amazing.
  The clean power this amp delivers is unprecedented, I have never had an amp for my highs deliver so, nicely! You would think I had new speakers installed as well.
  I must warn you, if you have any engine noise, get it fixed prior to installing this amp. I had a tiny bit of whining, (picked up at HU) since I replaced my plugs and wires. (used cheap stuff)  It wasn't enough to bother me, with my old amp. With this amp, it became unbearable, I had to take care of the problem immediately with new wires and plugs. Since that, I will give this amp 5 stars all day long!

I would recommend this amp to anyone!


 
awesome !!!!!!!!!! October-13-08
Reviewer: hightower from marion al.  
The best mids and highs amp ive ever owned ! Dont even think about it ! Just buy it ! No if, ands, or buts ! Very dinamic and sound so clean and so
real that your friends will all be talking about the way your stereo sounds !
The best words to describe the sound are AMAZING, FADELITY LIKE NO OTHER AMP ON THE MARKET, SOUND SO ACCURATE THAT YOU WILL SPEND
COUNTLESS HOURS JUST SITTING IN YOUR VEHICLE FOR NO REASON JUST TO LISTEN TO THE HARMONY COMING FROM YOUR SPEAKERS !

ive owned jl audio slash series, fosgate, and mtx amps. These alpine amps will impress even the unimpressable ! Thats A PROMISE ! Do not compare these amps to the older v12 series. The older alpine amps werent dynamic at all but the pdx series will make very dynamic ! people were telling alpine what they want in an amp and alpine was deffinatelly listening ! i can have the volume turned all the way up and cant even tell my stereo is on untill the first instrument is played. Just buy this amp and dont think u are gonna get anything but the VERY BEST ! If mine was stolen id call crutchfield and order another one instantly.


 
Mixed Review April-26-08
Reviewer: ppod from Cleveland, OH  
I installed this amp to power two sets of component speakers but was left with mixed feelings.  

The power and chanel separation is impressive.  The amp is also surprisingly dymanic when playing jazz and blues.  Unfortunatly, there is a significant amount of noise in this amp and as a result, I have returned it.  

Overall, it provides alot of power for the price but the sound quality is not acceptable.  I am told that the noise is result of the class D design.  If that is case, I think anyone interested in sound quality would be better served by a less powerful AB style amp.  Leave the class D's for subwoofers.


 
Great Quality November-30-07
Reviewer: Samyson from California  
This amp brought out so much color from my speakers. The power that it puts out really lets the mids sing, and the highs dance around your ears. The small package that it comes it can not be beat. My birth sheet said 168w rms and my components love each and every watt. They make my speakers get loud, and I mean LOUD without any distortion. I have to turn it down to not make my ears bleed. I was hesitant about getting a type D amp for my components, but I sucked it up anyways and was not disappointed. It did tons better than my old A/B amp that I got on budget. Very happy with this amp. You can not get a better amp for the space it takes up and the power it produces. It does get warm, but sitting next to a PDX 1000.1 in small, closed area does bring the temperature up a bit. Quality is not sacrificed. Keep on rocking.

Reviewer: MRMAP13 from Charlotte,NC  
Alpine PDX AMPS....  I have been purchasing car audio electronics from C/F for years.  Recently i purchased a large amount of Alpine car audio, IVAD-310,PXA-H701,RUX-701, to get a true theater sound quality. While using Boston Z6 components in all doors and focal center channel, the next step was to was to supply the power.  So after comparing, i decided on two pdx 1.1000 to power to jl12w7 and two pdx 4.150.  These amps not only were superior in sound quality, they were above and beyond the power rating stated.  A MUST BUY from C/F and ALPINE!!!
