Well I purchased this sub 2 days ago and installed it today in my Lexus LS400. I got the sub hooked up to a BAMF 2000/1d Monoblock amp at 1ohm and let me tell you, this sub hits really hard. I got it in 1.5 cub ft sealed box that I also purchased from Sonic, in my opinion that's all you need I strongly recommend this sub. I'm sticking with power Acoustik from now, nice product and affordable. The first is Sonic Electronix the shipping is always in good hands and right on time so special thanks to SonicElectronix for their service. i gotta go now, and for those that are getting this item i hope you enjoy it.

Put it in about a 2.25 ft3 ported box to about 33 hz in my girlfriends montecarlo. Her friends **** themselfs. she has air pushing out of the seatbelt guides for the front seats... these subs ******* beat lol

I just purchased. Two twelve inch Mo Fo's and a 2000w power acoustic estax amp and power acoustic cap even tho im under powering them by 600 each they blow my mind sound amazing i have heard rockfards P3's to JL audio W6's and these by far blow the P3's out of the water and with them under powered sound just as good as the W6's now im purchasing. A new amp that runs both 1100 watts so only 100w under powered i cant wait to hear them with the new amp i recommend power acoustic estax to anyony im hooked and will never change they look good sound crisp just try them and you then will understand.

All i got to say is man this thing hits and it gets loud... have it running on Rockford Fosgate p1000.1 @1357 rms @ 1ohm . just make sure you have the right amp and power source to run this mofo. Thank again to Sonic Electronix super fast shipping, great products, great prices, great service
thats why i shop at Sonix. THANK YOU!

Awesome sub!! I have it extremely under powered, I have about 30% power going to this thing and it shakes my car, turns heads and barely hear myself while yelling. Looks good and sounds amazing. Time to upgrade my amp to get full rang :)

this speaker was pretty damn loud people. i had ppl asking me if i had 2 15s.. and i would just laugh at em. i had it in a 33hz box, its awsome for the price and sounds sick i wish i hadnt bown mine so fast.. just be careful with em they can still fry on ya, but for the money i would recomend these to anybody that wants to heard from at least 3 blocks. but get 2, i cant even imagine 2 of em guys thier pretty loud.

I've had this sub over a year and it does really pound! I have it wired to a PHD-2000 Earthquake amp at 1 ohm. I haven't noticed that it gets hot although there is a slight burn smell if I haven't driven my rig for a few days. The sub sounds as good as ever and still pounds. The bass is clear and it hits the lows nicely. I would have to say I think it does better than my last sub.

I have currently owned 5 of these subs. Ive loved each one. Some of the loudest subs for the money. The only down fall i have is when you get some real power on them they get warm pretty quick but keep them in the rms and youll be fine.

I purchased this sub back in march and installed it in sonics 2.7 cubic foot ported box, and am running it off of the power acoustik bamf 2000.1d, and damn this thing slams. after breaking it in for about a month it started hitting full excursion and just got louder. tuning the low pass filter and subsonic filter on the amp just made it even louder. it moved a ton of air, gets 3" of excursion, and shakes just about everything. it does get very hot after playing it for a while, but after many months of intense heat cycles, it not only has held together but sounds better. all in all, i could not have asked for a better woofer for the price

I purchased two of these subs over a year ago and they are still running great. I have them hooked up through a Boss Audio CX3500D running at 2 ohms and it is LOUD. People can hear me coming a good quarter mile away at times. I would strongly recommend this product.

I had two of these in a 6th order blow through in a dodge dakota and it was very loud and clear bass. These subs have all the good components of competition woofers, aluminum basket, woven tinsels, pulp reinforced cone, high roll surround and a large magnet. Great buy and i would recomend them to anyone. Check out thebassmodel on YouTube for videos of them flexxing.

Amazing subwoofer. Great RMS and beats hard. I would recommend this sub to anybody

Absolutely fantastic sub. I have it in a ported 2 cubic ft box running off 1200 watts. It never gets hot and it hits like a champ. I would highly recommend this sub.

I would recommend this product to anyone looking for a cheap sub that performs. I haven't put a lot of real power to it. I have two hooked up to a Power Acoustik 3000D and they hit pretty well.

Man got 2 of these on 2 ohm and they beat. Dunno what fell off my car a minute ago but something did hope it wasnt important haha but ya well worth the money. Got em on 5500 bamf still breaking them in. Amp turned halfway up is more bangin than any set up ive had. Happy with my system, always wanted more, now i got it. Buy some!!!! Anybody that hates on these must have never had a pair.

These subs are absolutely insane. I had 2 Audiobahn natural sound subs that I blew on a 700 watt amp, so I replaced them with these and wow was it an upgrade. These subs only getting 350 watts each are so ridiculously loud. I would definitely recommend these to anyone that wants insane bass, I can't wait to get a bigger amp and push them to they're full potential.

I would recomend this sub to anyone it is a beast you cant buy a better sub for the price.

I have 2 of these going into a 98' Sunfire GT. Hooking them up to the Power Acoustik D1-6000D and a Kinetic battery, zero gauge wiring, and a Power Acoustik TI-931NB. That's a 9.3" touchscreen!!! Setting the subs facing into the interior through the hole behind the backseat. Will re-post and let you know results. And a link to the Youtube video.

I got one like 6 months ago. Before that i had 3 competition subs i kept blowing. Until i ran into the mofo one of the best subs ive ever owned so i just bought another one from Sonic. If your looking for a competition sub that wont blow up on you I highly recommend the mofo.

I have 4 of the mofo 122x on 2 Power Acoustik gothic ov1-5500d and they will take any power you give them these subs are the best i have seen by far i have doing installs since i was 12 and owned my own shop at 25 and still havent seen any thing come close to the mofos. I have them in a daily driver car and i push them to the amps full power every day and i have never had any kind of problem from them they never get hot witch i think is amazing but there is a warning they will rip your car apart if you know what your doing if you wanna be heard 2 miles and comeing these are the subs you want a pair will handle up to a 10,000 watt amp i know ive tried }:)

I've got 2 of these bad boys in the back of my 07 mustang with a custom box. They are good speakers but I wouldn't have too big of an amp cause my amp burnt the coils in the speaker. I had 2 3200 watt power acoustik amp hooked up to them. They hit hard for bout 12 hours then started smelling the burning smell. Turned my amp down but it was too late so I recommend you set your amp low.

I have owned this woofer for about 3 weeks now and this woofer hits hard. I had it playing next to my buddies car and I was shaking his car from the bass. I wild recommend anyone who is looking for a sub that hits to buy this woofer. I have mine powered by a 2000 Watt monoblock crypt power acoustik amp and it slams hard. I believe you will really enjoy this sub.

I've gone through numerous pairs of subs including Kicker, Rockford, Kenwood and MTX. When i purchased this sub i put it in the box i had recently built for the two kickers. IT sounded terrible. I almost sent it back, but i decided to order the 2.8 cu ft box from Sonic and give it one more try. Let me tell you this sub is amazing n im only running it at 4ohms on a BOSS amp. The BAMF 2000D should be here tomorrow so i can run it at 1 ohm. But overall i am pleased with how this thing sounds. The moment i put it in my truck (same settings as the Kickers) i told myself im selling the kickers lol. Not to mention i only have one MOFO and ppl 2 cars ahead of me said the can feel the bass!!! That made me sooo happy. Also this girl pulled up next to me said "Holy S**t" because she said i made things vibrate in her car.

Very pleased with this product from Power Acoustik.

Sub hits hard provided you make sure to do the big 3 upgrade on your vehicles electrical system and a good enclosure. My sub sees 1350 watts and handles it with ease. Only drawback is I should have bought the dual 4 ohm. Only because of configuration flexibility so I could add more subs without having to add amps. This is not a negative for the sub but a lack of planning on my part for future upgrades. You will not be disappointed with this beast!!!

Have had it for about 4 months now hooked up to visonik 1800d in a ported box in an 01 eclipse and it pounds. I've ran it full power since new and its never had a problem, I would definitely recommend it.

After a great deal of shopping and reading reviews I bought this sub. I can tell you, you will not be disappointed. I mounted it in a 1.5 cu ft sealed box as recommended and have it being pushed by a 1000 watt amp wired to 1 ohm. INCREDIBLY CLEAN sounding. I have it mounted about 2 feet from where I sit and there is absolutely no rattle, just amazing sounding, deep, tight bass. I would definitely recommend purchasing this to my friends, but make sure you get a beefy amp because this thing pulls some power.

I have 2 of these in my chevy, 4.25cubes 52 sq inches of port tuned @33 hz with planet audio tt2250d @ 2ohms 1500 watts rms litraly breaking my car, cant keep the trunk lid on my car best subs I ever had louder than my buddies orion hcca 12 in his obcon freak box.

I bought two of these subs after a long thinking process an now there the best I have owned...the bass is mad.

I bought this product of Sonic Electronix and got it in about 4 days. Received it in a nice big box with tons of fun peanuts and got to dig out the box the subwoofer was in!!! :D anyways, in installed the subwoofer into a vented enclosure tuned to 32 hz and hooked it up to a 1200 watt amp and it sounds amazing. This sub hits harder than any other sub ive ever had and sounds clear. This sub will not disappointing you, I recommend it to anyone who wants a great sub and that doesn't want to spend their whole pay check. Only thing im curious about is this subs dust cap seems to get very hot, other than that great subwoofer P.S I have this sub wired down to 1ohm.

Great sub for the money. Comparable to high end subs for 1/4 of the price.

I have owned two 122x mofo's since about October of this year. Since i bought them i have gone through 2 "2000" watt amps with them, i didn't want them to be maxed by any means. I am selling the subs (now 6 months later) because i don't want to buy yet ANOTHER amp for them, if you get the right amp they will make your ears bleed, if you don't they'll work for about a month, maybe two, then all of a sudden the amp will go out on you and you'll have just another 100 pounds sitting in your trunk

These subs are great. I wanted something cheap but with good sound. I had two boss phantom subs for one week and smelt them first time I ran them. The mofos have ran on the same amp and box set up and haven't even got warm on me. The sound difference is amazing. Would def. recommend to anybody on a budget. The only thing that makes me leary is no recone kit

Best sub I ever bought made my windows shake

This sub wazz the best sub I ever bought I had a Boss Audio sub and my mofo killed it I would prefer the mofo sub to anyone

Just got it hooked up to Crypt 3200D amp and i hits like crazy, would def buy another one

I bought the last model of this MOFO Christmas day of '07 and I still use it. These things can handle some abuse, however they require some power. When i first got it it was hooked up to a little Pioneer 750, and it frequently shut it off from getting hot. Now I either use my JBl amp or my Sundown for it... which is what a powerful sub like this one requires. Gets deep in the lows, yet keeps up with fast hitting rock. Take it from me, if you want something to last then this is the right one for you.

I wanted a cheap, inexpensive system that could bump a bit. I was going to buy another RE audio subwoofer, but decided to give one of these a chance since they are quite a bit cheaper, and I could also resell it if I didn't like it.

Boy was I surprised! It sounds nothing like the Fubar series. I put the subwoofer in the largest prefab box I could find (2.8cubes ported, not sure what the tuning is, but probably pretty high) and it sounded great! It didn't hit the real low notes all that well but it could have been the box it was in. Also I am use to 15's in larger boxes so that could have also been a factor since I'm use to the low notes. But all in all, It is well worth the money.

For the record, the amp I am using is a Hifonics 1610D and I'm running it at 1ohm. The whole system cost me ~ 400 dollars

First system ever and everyone thinks i'm crazy i got 2 of the 12" mofo's with the power acoustik 5500 watt amp and tbhey bang......Hard! I have the amp not even up half way and you can feel the pressure on your body when the radio isn't even on full blast i would def recommend these to anyone and everyone

I have this on a 200rms 400max vr3 amp and this is louder than when i had 2 12in sonys on 2 of them amps. This is one of the best subwoofers i have ever bought.

yes brutal, and mine are way underpowered, i have mine hooked to a fosgate prime r500-1@2ohms in a ported 2.0 cubic foot per chamber box. each sub is only getting maybe 300 watts and i get good roof flex, nothing in my car stays where i put it not even my passengers stay put for very long. also i must commend the build quality of these subs they weigh about 30lbs a piece and are very well constructed. plus price/power ratio is nice.
Great price and great service.

This thing means business, I have one hooked up to a Kole Audio 4000d amp getting 1700 watts at 2 ohms, upon the night I installed it 3 of my neighbors called the police. It roars in my 04 ford Taurus even as its hooked up to my stock head unit. great sub, great price, from a great company, thanks sonic!

I've got a 92 honda accord wagon with 2 12" mofo w/ memphis 1500d hit 149.8. I'm adding 2 more of the 122xmofo, memphis 2500d & 6 2 farad caps, cant wait to hear it. my goal is to hit a 155. these subs are awesome. when put to the test they will speak for themselves.

you don't need a bigger box the sub actually hits the best in a 1.5 cubic box if sealed. if you put it in a bigger box then it wont be as clear and crisp. now if its a ported box the you want a 2.0 cubic box and no bigger or smaller. it is a phenomenal sub and i had 2 in a jeep and was winning competitions.

I have owned one of these for almost two years now and I love it. It provides tight clean bass, is very loud and plays highs and lows. My friends tell me all of the time that they could hear me before they could see me. It is hooked up to a poweracoustik 2000 watt mono BAMF amp. The one problem that I have with it is that my box isn't quite big enough. I have a 1.5 cu. ft. box and it's not nearly enough. I would get at least a two cubic foot box. This subwoofer is well worth the room that it takes up in your backseat

i have 1 power acoustik mofo 122x hooked up in my infiniti with a 3000 watt 2 channel pyle chopper series amp with a 3 farad power acoustik capacitor and i out bump my friends who have 2 or 3 subs in there car AMAZING PRODUCT highly recommended

THis Sub is amazing. Slams so hard i have a 1200 watt mono block hooked up to just one and it blurzz my vision .

I have two of these matched with a PA 6000d demon amp and they slam like nothing else! They hit everything loud and clear no problem. I can now boast that I've shook things off the walls of my house too! Be sure to keep them in the RMS range and you're golden. They take so much power though that you probably won't have a problem with that! I was a bit worried with it being my first time with Power Acoustik but it definitely paid off. As the title says, they have my pair of earthquakes beat in every category possible and take up less space!

Now i would most definetly recommend this subwoofer to anyone. i already have. I have one of these subs in a 2003 pointiac montana ext hooked up to a power acoustik lfa1-4000d amp at 1 ohm and damnnnnnnnn!!!!!!!!!!!!!!like FRENCH MONTANA said "everythings a go" .this ish is the best.and gues what,i bought it 2yrs ago with the amr too.0 gauge wire/9 gauge spkr wire.all power acoustik gear in my van.ppl hear me comin and when i get to ppl houses,they walls n windows shake.imagine sittin inside and thats with ONE OF THESE!!!!!!and anyone who doesnt believe me, get that combination and you will see and people around here are hooked on that alpine crap 2 of them cant hang with my 1.......

It was an awesome SPL sub very loud! But in a 4000 watt Amp lasted only 1 month and melted the coil! But if I had the money I would buy 2 of them for the same amp! Just to see again house window rattles and car alarms go off

This sub is a beast! I owned the original MOFO 12 and it was loud. The 122x in a 1.6ft2 ported box with 1200RMS in a Geo Metro. Only one word can describe it.. INTENSE!

I will be soon adding a second 122x and a second BAMF-2000D to power it.

Need a big amp for this sub... I hooked up a 1600 class d amp to the mofo and upgraded my batt... Let me just say this you will not blow this sub up and it slams so hard... Bad boy

I've had this sub installed in my Cavi for about a week now and this thing is over the top loud. I had it in a 1.5 cu" ported box wired 4 ohms mono through my 1200 amp and it was so loud it made the windshield wipers vibrate..., and thats only at about 3/4 gain! After a few days of that I switched it to a sealed box with a lot of polyfill and tried it again. So smooth and deep sounding it almost brought a tear to my eye. Also, if you listen to alot of double bass it hits that very nicely as wel. Solid performance across the board for this sub. If your looking for a sub that does it all than this is your sub. Oh and thank you for the quick delivery Sonic your service has been excellent.

Just bought one and it is a big thick sub, solid feel to it. Hooked up to a crypt series PA amp hits extremely well. Only 140 dollars absolute steal! After in stalling this in my mustang I realize I now need dynomat!! Can't comment on durability because I've only had it for a week and I'm still trying to get it worn in. Go for it trust me!

I have now ordered 2 pairs of subs from here and have been very pleased on both. My most recent purchase of the Mofo has been one of the best decisions I've made. They hit hard, and look really nice. I really love the low bass these subs put out and as a first time user of Power Acoustik I am vey pleased. I have gone through MTX Audio and Pioneer and both have failed me in some way within the first year of using. I'm very happy with these subs and would recommend them to anyone looking for a hard hitting, competitive sub that sounds just as good as it looks.

Bought this about six months ago.. never had a problem, have it in a vented box and the range is awesome if u want deep rubble put it in a ported box at 1000 Watts. Enjoy

I got these subs a couple days ago, and have them wired to two Power Acoustic Crypt 4000's and they bannnng! My brother said he could hear me from the stop light around the corner from my house, good buy for my first system. Also installed 2 MB Quart component sets, a P.A capacitor and a Pioneer head unit.

Got two of these bad boys in my chevy and they hit hard. I'm very pleased and cant wait to get my new amp to max them out! I love the way they hit the lows and I highly recommended them.

Right price and it's all over YouTube!!
I got the 5500 crypt series and 2 MOFO122X's
Troublesum!!!So as i'm told
I got the right amp and the right subs
Just on the fence about the box
I want the best bump no losses!!

I blow the sub in 5 minutes or less on 1000 rms MB QUARTS mono amp, the subs are way over rated in wattage, i wouldnt recommend this sub to anyone, the coil cap turned insanely hot in 10 seconds of running it, only credit i give this sub is it moves but didn't produce much bass at all.
