Great amp if you want a tremendous amount of sound.

Summary: Using this amp to push 2 - 12" Alpine type Rs max RMS 600 each. Works too well, gain is almost off and the highs still get drowned out. Need a 4 or 5 channel PDX for the highs now. I like the stackable design, small size and clean look but wish it had a cover over the connection.
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. And it's small enough to fit below the front seats of most vehicles. Great product.
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. Light dimming went away without an extra battery or big 3. I was disappointed by the fact that the mounting holes are in diff spots and had to fix up amp rack to hide holes. Just fyi, these don't stack with the old pdx amps.
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. The stacking feature is fantastic, and they are a nice clean amplifer. 4th order crossovers are great, but that is all you get. Made for power in a small effecient size.
Summary: Go this bad boy paired up with a Kenwood KNX7180 and a 15" woofer in a custom to spec ported box, and this thing puts out way more power than my old PDX1.1000 put down. Compared to the last gen PDX this thing is a heck of a lot more efficent (Same max current draw with 200w more RMS guaranteed on TAP) Only feature i find truly lacking with this amp is the variable SSF (More options than just off 15hz and 30hz)
