Summary: i installed this amp 4 months ago and i have to say i am so glad i picked this amp. i had a few others but none made my music scream with the clean, clear power this baby has. says 150x4 mine birth certificated at 189x4. i'm an old 60-70's rock n roller. who knew pink floyd could sound so good.... just rocks the doors off my dodge quad cab. latest in a long line of outstanding alpine products.
Pros: so simple to hook up and adjust to your tastes. will make your ears bleed on the highs, clear tones on the mids, and thumping driver on the bottoms.
Summary: I upgraded from the Alpine PDX-V9 because I was looking for a little extra volume and detail from my speakers. The PDX-F6 delivered. I'm getting a lot more volume and a lot less distortion from my speakers. For example, tracks from Johnny Cash would often make my midrange driver distort at moderate volume levels. This is no longer a problem. I was very skeptical of these new Class D amps but I will continue to buy Class D for car audio. It just makes sense.

Conclusion: Excellent amplifier - well worth what I paid for it. Runs slightly warmer than expected for a "class D" amplifier, but delivers what I expected and more. The use of plugs instead of screw-down terminals for the power inputs and speaker outputs is a definite plus.
Conclusion: This is the 4th PDX amp I have owned. I have the first gen amps in another vehicle, and was impressed so the new ones are now in my new vehicle. I have this stacked with a M12 under the seat in my pickup, power 6.5" compoents and 6x9 coax speakers. Plenty of power from this guy. All the features work great and it does everything I need it to. I wish it had rca pass-thru's but it is not that criticle. Build quality is top notch, and they are clean as can be.

Conclusion: The PDX-F6 was easy to install gives me more than enough power for the small SUV its mounted in, its driven by an Alpine INA-W900E (not happy with the firmware too restricted) Vifa speakers with a Focal under seat sub (120W) there have been no complaints about the sound quality or volume.
Conclusion: This amp gives my bike the power to slap with all the others with just 4 6*9's and 4 6.5's in my fairing all i need is for you to call baggers magazine and spread the word about this slappin amp.
For loud sound accuracy in a small package I recommend this amp.

Summary: This amp pretty much killed my last 2 A/B amps both of which were running bridged mode and taking up 4 times as much room and producing 20 times the heat. The refinement and detail of this modern class D is unbelievable to be honest. The control it has over the mid drivers now is much improved. It's tiny as well. I'm in a small hatch but this (+ a mono-block) would suffice for most peoples needs (Just look at the specs!
Conclusion: I'm using my PDX-F6 to drive 2 pair JBL C608GTI MKII after an Alpine PXE-H660 using my OEM 2010 Mustang GT Shaker HU. After calibration with my PC, I'm VERY pleased with the results! This AMP is perfect! Powerful, small, cool and LOUD!
Conclusion: I bought this amp about six months ago and installed it upside down and covered on the back deck. Its digital, so it runs cool and worry free even when pumping out the watts. It also seems to sip power, with a reduction of electrical load on the factory alternator. The connections are awesome too; screw them into a plug and THEN plug them into the amp. Great for working upside down in the dark!
