Conclusion: This amplifier is in a class of it's own. No other amplifier pushes my RF T2 12 like the Alpine M-12. This amplifier never gets hot, has amazing clarity and is easy to tune. I do not want to list the amps that I have used to compare this with but the M-12 wins hands down.
Great Service and Fast Shipping and Genuine Product

Conclusion: I haven't had a chance to install this amplifier yet but this review is solely based on my experience in ordering this product. I was a bit skeptical at first because Sonic wasn't an authorized Alpine dealer but after opening the box, everything looked like it was just shipped from the factory.
Conclusion: Not the most powerful amp I have ever owned but definitely by far the cleanest. A bit pricey for the power but you probably won't find cleaner sound from any other company or amp. Very small and compact easy to hide (if you want to that to this beautiful amp).

Conclusion: although i didnt buy this amp from sonic, cuz it wasnt in stock when i needed it jus like most items are never in stock when you need them with sonic, i got this and hooked it up to a RF T2412D and this little guy is so powerful and efficient, doesn't heat up, doesn't draw too much current and im...
A powerhouse, but take your time to set it up right

Conclusion: When I first installed this PDX-M12, it sounded a little "thin" compared to my previous 500W Class D amplifier. Turned out that I needed to adjust the gains somewhat. Now it delivers all the clean power that I, or almost anyone, would ever need from a subwoofer amp.
Conclusion: I have had this amp running for a few months now. I upgraded my old pdx 1.1000 to this amp (old is still sweet) There was a noticeable power and sound difference where amps clipped used smd dd1. This amp uses a lot less power, than the old one.
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. Birth sheet says 1376 watts RMS. They are driving my two 10" Fi SSD woofers very nicely. No problems overheating and nothing to complain about.
