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. I'm running two 13w6v2's on this amp, and it barely warms up after a couple hours of working hard. It puts out better sq than old pdx, producing richer bass. This amp is great, but lacks a couple features eg. bass boost. or at least they could include the volume (rux) knob for the price.

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. No bass boost, phase adjustments or other crap that some of these other manufactures are loading their amplifiers up with.

I bought the PDX-M12 along with the PDX-F6 and both perform beyond expectations. Driving a pair of 12W6's, sealed; Sharp. Crisp. LOUD. Slight warmth felt after an hr pounding. I'm very pleased with my purchases. There is only one smell better than a new car smell and that's new AMP smell!!
