Convenient

So convenient being able to control the gain from the car.

Great item

Works as it should. It is a solid knob. Not cheap like others

Good quality fast shipping

Great product fast shipping great customer service will recommend to friends

Awesome Product!

Purchased the MRV-M1200 Alpine amp which already comes with the previous version of the Rux Knob but figured I'd give this one a try. Best part is the larger db adjustment range with this 2.0 version.

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!!

POWER,SOUND,SEXY !

Bought this amp very happy and please I'm using this amp with 2 12" Alpine Type R in sealed box it SLAM and HARD POUND ! Sound very CLEAN AND CLEAR AND LOUD. BEST AMPLIFIER !

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.

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

Amazing!!

I have had this amp in my truck for almost three years now powering my JL audio W7 and no problems what so ever. I love this amp and i plan to get three more of them.

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.

Awesome

The SHEEEET

Nice little powerhouse

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.

Great Service and Fast Shipping and Genuine Product

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. Andrew was my salesperson and he patiently answered all my questions and followed up with me whenever I left a message regarding shipping or additional questions about the product. The amplifier was delivered to me within 3 days which included free shipping. Add to that, I received a great price as well. What more can you ask for.? I highly recommend these guys and would absolutely buy any electronics products from them again without reservation.

Easy install

Easy installation and works as expected. Disassembles easily for flush mount behind dash, which makes for a very clean install. Just plug it in and it works. It definitely has the dead spot as mentioned on other reviews, but was expecting that. Rux-knob.2 has a higher db adjustment as compared to the original model (20db vs 12db). Worth having installed on your system!

Alpine PDX-M12

Have two of these amazing amps each to an Alpine type X. Switched from brutus amp and almost doubled the bass

Powerful!! Quality!!

I have compared this amp to my HD750/1 and my Rockford Fosgate BD500.1. It is on par with both of these amps. The JL has RIPS technology that is a plus above this amp in terms of wiring but the Alpine is just as strong ( in my opinion sounds better - more realistic & full / dynamic). Heavy. Quality product!

Great product, thinking about ordering another one

I would definitely recommend this product as the Alpine PDX M12 delivers the power necessary for your subwoofers at the efficiency of an amp two to three times the size of it. This works in your favor if you are dealing with limited space with huge desires for power. Sonic Electronix makes it even better by offering the product at such an affordable price with shipping rates and speeds worth cherishing.

Great value, delivery on time. I totally recommend Sonic electronic. The Best!

I totally recommend the PDXM12 it is a great Amp.

Decent for the price

Good, strong but efficient amp. I like that it can be used for subs or full range.. but it's only one channel which isn't very convenient. And it's not 1 ohm stable. Also, after having it for about a year, the power plug gets loose and you have to get another for 50 bucks. Gotta order another plug, I've had this amp for just over 2 years..

Alpine PDX-M12

Installed this amp a week ago with 2 10s and it works perfect in my Toyota Tundra. Highly recommended

Alpine PDX-M12

This amp is high quality and puts out more power than stated.

Alpine

This is a cool little amp and at the open box price Sonic had it was hard to pass on. I liked it so much I went back and got the 4 channel that piggy backs on top. My other sub amp is rated twice this but the alpine is 1200 at .03 and 4 ohms. Better specs. Mounting and wire connections are better than most. Controls are under a panel held on by a screw bit of a pain but looks clean. I have a 12 Alpine R but this is driving a 10"square Kicker in a ported box. I went online and found the remote knob. Great specs easy clean installation. Controls are good but need a cover removed to adjust. Nice single light. Better with the control knob. Great wit the other amp. I'm an Alpine fan because the R series fits I'm building a system in a Saab 900 with new Clarion head trying to keep a little to what names where there in 1991

Fantastic

It works with a Alpine mrx m110 plug and play. Super high quality knob that is really well weighted. I would suggest aswell buy again.
