Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
MOFO (Power Acoustik)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
2700 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
1500 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Dual
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
2 ohms
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
2.5"
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
23 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Black
Blue
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Cloth Laminated Paper
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Foam
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
No
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / Vented
Sealed
Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.50 cubic feet
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.50 cubic feet
Minimum Ported Box Volume
This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
2.0 cubic feet
Maximum Ported Box Volume
This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
2.0 cubic feet
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
6-1/2"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
11-1/4"
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

Mofo 122x perfect sub

October 16, 2010

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.

MOFO 124X

September 9, 2013

Ive had 2 of these for about a year now coupled with the BAMF 5500/1D wired to 1 ohm just a little of half way on the gain pushing approximately 1300 rms (JUST A NOTE THE 5500/1D DOES NOT PUT OUT WHAT IT CLAIMS, NO MORE THAN 2000 RMS!!!)
Best dB metering is 145.2 @ 43hz with a pro box giving each 2.5ft.
Budget system that I am impressed with. Getting 4 new MOFO's as this sub can not be re-coned, Only bad thing about them. Great sub for the price and people have been shocked when they hear that its only 2 12's.
Do not play for long periods at high gain levels as the sub will heat up quickly.

Awesome sub, if you buy the right amp

April 25, 2011

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

quite impressed

October 15, 2010

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

Bad@$$ Mofo NOT

April 2, 2015

I got one of these from another dealer. It's rated at 1500 rms and 2700 peak watts. I hooked it up to the Hifonics BRX 1200.1 @ 1 ohm and it hit pretty hard for about 8 or 10 minutes and that was the end of it. 1200 true watts smoked it that quick. I have never had a sub blow like that. What a joke I absolutely would recommend not buying them they are cheap junk.

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.

Awesome sub

December 18, 2011

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.

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

I been using power acoustik amps for a while most of my friends use the amps as well. I have heard that the subs were not that good I use mtx subs in the past but wanted to try these. Let me tell you I have one mofo 12 at one ohm hooked up to a 4000 ov1 power acoustik in my Nissan titan and it's dam loud. The only thing is I wish I could put two of them in my truck. For the price and to only have on sub it's insane of how loud it can be.

November 27, 2012

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.

Damn good for the money

September 7, 2012

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'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.

Amazing subs

January 9, 2012

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.

June 23, 2011

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.

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.

Still Bumpin'

January 22, 2011

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.

Great sub

July 31, 2010

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.

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!

phenomenal sub

May 3, 2010

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.

mofo 122x and BAMF 4000 1/D

March 13, 2015

I hope this mofo up to my BAMF and pushed 1700 watts to it and it lasted almost a week before blowing up the sound was phenomenal but I just upgraded to a 15 inch instead and that was a perfect match.the sound of the 15 inch hooked up to this BAMF is incredible!

Great low output sub, frequency range was disappointing

April 27, 2014

This woofer is a good solid speaker for what it is designed for. Nice loud clear bass on the low end, but there is a definite lack of performance on the mid/high end. i personally prefer a woofer with a wider range, but it is still a good woofer for what it is designed for, deep loud bass. definitely recommend for multiple woofer system where the highs are covered by a smaller woofer, or for a low end competition speaker. good product by power acoustik who i use lot of products, great job sonic, great prices and fast shipping as always!

RIDICULOUS!

March 17, 2014

This thing is ridiculous! It's amazing! I bought one (1) of these to replace 2 JL Audio 10W3's and I couldn't be happier. I only feed it probably 500-600 watts of power and it pounds! I can't imagine if I added the actual power that it is rated for. I use a SoundStorm (SSL) EV1500M wired at 4ohms which is supposed to give 600watts into 4ohms, but I don't have the gain turned fully up. Anyway this thing is amazing, and puts out lots more sound than my 2 JL 10W3's did with 400watts each!
Stop thinking about it and buy these subs. You will not be disappointed.
I listen to nearly every type of music, and like heavy bass even with music types not typically associated with such, so this thing is perfect!
I bought the package deal enclosure with it as well, and am very impressed with the quality of it also. The only downside for me is now I need to find a way to hold my rear-view mirror still, as it is now always vibrating out of adjustment!
Buy this sub!

I would have never bought these subs just because I never heard of them before but after reading about everyone loves them I bought 2. All I can say is damn... These can get painful.. I have my amp turned up a quarter of the way and my glass does the wave. I recommend them for anyone, they're built very well. Over power them though, don't under power.

Better than my pair of 15" Earthquake Tremors

November 23, 2012

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!

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.

Superb sub!!!

January 4, 2012

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!!!

Mofo 12 2x

January 5, 2011

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.

Power Akoustik Mofo 122x 12" 6mnth sub review

December 9, 2010

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.

brutal subs

July 31, 2010

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.

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

One of the Best Purchases I've ever made!!

April 20, 2015

To cut right to the chase....two of these hit...HARD!!! I didn't believe the reviews at first myself but they actually held up to the hype. I feel like I would never have to upgrade to anymore subs either. They are reliable and pack a punch. If you have the right set up, these will last you a lifetime and you won't be disappointed. I don't know what else I could possibly say about them.

It makes my doors flex lol but on the other hand these speakers at heavy as hell! I was a bit sceptical about buying these but now I couldn't be happier with them. Just make sure you break them in!

Best bang for the price

September 16, 2014

I currently have 2 of these subwoofers and im extremely impressed. When i installed these in my subwoofer box (also bought on this sit) it was too big for my trunk. I proceeded to throw them in my back seat till i came up with a plan to get them in the trunk. When i first turned up the subwoofers (back seat) alot of air was beeing pushed out the ports but my mirrors on and in my car barely shook, i was very disappointed. I finally ripped my trunnk completely apart and got the box in. My trunk doesnt stay open but who cares? I turned up the radio about half way and my center mirror dropped like it would in a bass competition. Im very impressed with these subwoofers and would deffinatly buy more! I have 2 Power Acoustic 2400D amp. I installed everything myself and couldnt be more impressed. Deffinatly wouldnt pay $2,000 for a audio company to setup crappy kicker that dont sound anywhere near as good as my system.

this sub is awesome

January 27, 2014

let me start by saying, i am new to power acoustik being in my car and was quite skeptical, i purchased 2 of these, along with an obcon compettition ported box, and this thing can bang for days. i truly say if you are debating whether to get 2 alpine type r's, or 1 orion hcca, this sub will out power those with no question with clarity to back it up. on top of that, i have been using a 1000 watt ssl amp, which is only feeding these subs 250 watts rms a piece!! I am louder than my friend with 2 10 inch jl audio w6's which is incredible because he payed twice as much as i did lol. but make sure you break in the subwoofer with a weak amplifier before you 1 ohm it, or run it to a massive amplifier. i am going on 3 months with the 1000 watt amp and Im soon to get a power acoustik gothik gt1-4500d, i have done amp research for a quite long time now, and decided thats the one im going to go with. but otherwise, if youre thinking of getting this sub, you will not be dissapointed. i love mine, these things are crisp and clear, and they bang so hard, this thing is 6 stars, and out i absolutely love them

Very nice Punchy, Thumpy and Thundery type bass

January 22, 2014

I know that the Subwoofer Enclosure (Sub Box) plays a big role in subwoofers performance but a lot of credit goes to this sub. First off when you open the box up and take the sub out you will think you ordered a 25 pound dumbbell, yes it really fells like it weight about that much. The look it excellent and has nice covers to cover up screws from showing with you install it into a Subwoofer Enclosure. I have a 3400w boss amp pushing it and it is handling it very good running at 1ohms. I have it installed a 1.5 Cu FT Sealed Box that has Poly Fill in it also and when the speaker plays it HIts Very Very strong. If you like that bass where it fells like someone has a big Hammer and banging it on the back of your FRONT seats then look no farther.

Other notes:
It HIT the Lows very nice
Having it in a ported box may make it even louder.

MOFO-122X

October 8, 2013

I put this in my truck to add some bass and ended up with a hard hitting sub. This sub was worth the money because of the 340 ounce magnet being in a 12 inch sub makes it hit so much harder. I am only pushing 1100 watts and beating some of my friends pushing more through their 12 in subs.
Pros:
Looks good
easy to install
Great for an extended cab truck
Cons:
No problems with the sub

Bad product!

May 10, 2014

You get what you pay for when buying this product. It's cheap and that's exactly what the product is. Cheap. I hooked this sub up in series at 1 ohm to a belva 1200w rms amp and I was still in the breaking in period (1/4 gain/power) and only had it on for 15 Mins when the coils burned up. This product is way overrated power wise and probably can only handle 400w rms max. Not only this but the company won't let you get a refund either when the sub is clearly overrated. This is the second and last time I will ever buy a power acoustik product and more importantly one of there cheap subs. I had a problem in the past with one of there 15s doing the same thing but I gave them the benefit of the doubt and tried them again. Bad mistake. There customer service is pretty poor as well while on the phone with them. I will stick with buying the good stuff you pay more for, like Orion for example. I have a 15 on a belva 2000w amp and it hits hard and doesn't burn up or even get that hot.

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.

Good lows Good XMAX

August 12, 2014

Top notch woofer for a great price. Has great lows but don't expect any higher frequencies like over 150-250 hertz thanks to the heavy voice coil cap. Could use better quality control but I think that's the reason for the price. I am running my MOFO 122X on 900 RMS in a sealed 1 cube box and it throws over an 1.5 inch, shakes everything. On a second note about the voice coil cap, it does work great as heat sink.

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.

Andrew E on Mar 14, 2015
so in love with these even tho they are some what slopy you can make the amp pick up the slack when the subs need the phase or 180 what ever. still very happy and they can take 2600 or close I have two of them on a hifonics 2600 amp

hi......i have Planet Audio AC4000.1D ANARCHY 4000-watts Monoblock Class D 1 Channel 1 Ohm Stable Amplifier and Power Acoustik MOFO-122X 12-Inch Competition Subwoofer Dual 2-Ohm Voice Coils.Can I put the IPUT LEVEL Amplifier on max??? or will burn the subwoofer????
A shopper on Nov 15, 2014
Best Answer: gains are not a volume control. you can find alot of things on the net as to how to set your gains correctly to keep from frying amp/sub or both. your headunit has preouts those preouts have a voltage set your amp to the preout voltage to atleast get a base to start from so as to not fry something. exmpl i have 4vlt preouts on my pioneer and have my pioneer amp set at 4vlts on the gain. im only giving my mofo 1000 max at 1ohm right now but it gets down low and loud even though my enclosure is a prefab and underspec. new enclosure drying now.

What would be the best amplifier to use with 2 of these subwoofers?
A shopper on Jan 6, 2015
Best Answer: A mono block that puts out 2000 watts rms should do them justice they are over rated and can say comfortably that they are under or around 1000 watts rms a piece. That should be nice and they sound really good in custom boxes. You want 3 cubic feet per sub for max output

Best Answer: Hello Timos, This subwoofer is a Dual 2 ohm, its important that you address is properly to avoid confusion. It does have the ability to be wired down to 1ohm, but this will NOT 'burn the subwoofer'. The impedance of a subwoofer is never the factor that "burn" it out, its often an improper setup that does that. If you want the figures to match with the AC4000.1D, then you want to consider the Power Acoustik MOFO-124X instead. Two Dual-4ohm subwoofers wired in parallel will give you a 1ohm final load.

i'm trying to decide if i should buy 2 of this or a orion hcca 122x what would be louder on the trunk of my car?
mayitodmngz m on Sep 30, 2014
Best Answer: Both speakers are great of course the orions are the loudest but in my opinion the Power Acoustik mofos are right up there with them which speaker I would choose I would go based on how much amp power lm using the rms for the Power Acoustik is 1500 watts a peace the rms for Orion 2000 or more Power Acoustik you can't beat the value for the money and like orion thay can take abeating

I have a Hifonics BRX 1200.1 mono block amp and a 2.0 cf slot ported box tuned @ 32 htz with a Hifonics OLM 800 D2 I originally wired it to 1olm to get 1200 watts and my sub couldn't handle it. So I wired it to 4 olm @ 450 watts and it sounds much better. But it still doesn't hit hard enough to satisfy my need for really hard hitting bass. Would the dual 2 olm MoFo handle the 1 olm 1200 watts and hit 2 or more times harder than my current sub or should I just go dual 4 olm and get 2 Mofo124's with a dual 12 box?
rokstar on Mar 19, 2015
Best Answer: If you are only running one mofo that is fine and will handle the 1ohm stable if wired parallel but that amp is a lil small the mod I rms watts is 1500 and max is 2700. So it will run 1 mofo 122x but be a lol under powered.

I've got a 2400 watt max Kicker amp and thinking of buying this sub.... is this a good choice or should i look elsewhere?
jake n on Apr 21, 2015
Best Answer: Hello Jake,

We may need to remove your question because it is a bit too vague for us to feel comfortable enough to leave it up. You've only provided a description of your amplifier, instead of a proper Model Number, so all answers you receive will Only be guesses. Kicker often does Not rate their amplifiers with "Max" figures, instead of RMS figures, but there was a time they did. Assuming it Is a "Max" figure, then the amp is likely doing 1200W RMS at its lowest impedance. This is where the problem is, we have no idea what amplifier you are referring to, so we can't guess beyond this. For future inquiries, please make sure to provide a model number, not a description.

I have two of these hooked up to a 6,000 way spl ape class d mono amp at two ohms. Cea tested runs 2500 watts at 2 ohms and 14.4 volts. My box is only 1.85 cu ft and sub recommends 2 cu ft. It's a slot ported box port is only 12 inch by 1.5 inch. Tuned at 37 hrtz. Should I reverse Mount them to maximize box box space. Also have poly fill to trick su s into thinking they are in a bigger box and I still don't think I'm getting the soound I should from these. Or should I just get a bigger box?
A shopper on Feb 28, 2015
Best Answer: Reverse mount to me is silly. Its all about showing your magnet off. So unless you are going for show car applications just match the box size as close as possible. If you are listening to hip hop then your port needs to be perfect. If your listening to dub step or things with lower tones even Metal having nice drum hits. Then ported box wont cut it. You will sound better with a sealed box as long as you have the rihgt RMS going to your sub.... I know i blew this sub with a lanzar amp only giving it 1000 watts rms with a ported box. it did sound alright until it blew. But for the magnet size and weight to me its a underperformed speaker. My MOFO could not handle the ported box for more then a week. its little bit more but Im running an orion H2 12 inch with an older PPI amp at 1 ohms 1200 watts and its like night and day between that set up

Best Answer: Hello Timos,

There isn't a 'Right' answer to your question. Especially true, "quarter of the way" is NOT A PROPER setting.
*The Low Pass Filter [LPF] is the crossover setting that will cutoff/roll-off Frequencies ABOVE where you set it. For example, if you set it at ~120hz, then the amp will only allow the frequencies BELOW 120hz to play through. This is solely YOUR preference, but being a 12" Subwoofer 80hz-120hz is a common setting, however.
*The Subsonic Filter does the Opposite of this. So, if you set it at 40hz, then the amp will only play Frequencies ABOVE that. You often set this to what the enclosure is tuned to, because the enclosure - in theory - will cut off all frequencies Below that tune. ~35hz-40hz is the common setting.

For this example, if we set the amp the way I've explained, the the amp will play a solid range of 40hz-120hz , which is where the Bass is.
