AWESOME

This amp is worth every penny!! Its powering a JL Audio 10W7 in a ported box. I also have the matching Alpine PDX-F6 great combo and they work beyond expectations.

WOW

I just bought this amp to replace the new JL 1000/D that I was pushing my two alpine type r's the newer 1223/D model I have them in a dual slot ported box in an 03 tiburon and this amp slams I can beat on them from one town to the other with this amp and it barely gets toasty I would recommend this amp to anyone who is looking for some serious power.

A powerhouse, but take your time to set it up right

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.

Great little amp.

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.

VERY pleased!

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!!

Alpine M-12 worth weight in Gold

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. The price paid for this amp is worth it's weight in Gold.

Great Amp

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). Made my 2 12's not only pound but very musical. Would recommend to anyone who wants a super clean system.

super efficient

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 still running stock electrical and a optima yellow top, but just to be on the safe side i have a 2 farad RF cap to keep things running smooth, this amp delivers. i would buy it again if i ever need to
