Power Acoustik MOFO-124X 12" Subwoofer

When technology advances, products do as well. Does Lamborghini need to refine their cars every 2 years? NO, they do because they can. After 6 years, it is time for a change. Say "See Ya!" to the old MOFO, and welcome the new MOFO-X subwoofers! The new motor is refined and increases efficiency dramatically! MOFO-X subs use a non-pressed pulp cone for durability and smooth low bass. Like the original MOFOs, the new models use an aluminum dustcap that couples to the voice coil former and extends over the cone. Why? The fins brace the cone and eliminate cone flex during high excursion. Since the cap is aluminum and coupled to the coil former, it acts as a heat sink or heat extractor. Using the latest materials, the new MOFO-X subs yield superior performance!

Enclosure Recommendations

All enclosures should be made of .75" (3/4") material only. When possible, make the baffle 1.5" (1-1/2") thick and add .75" (3/4") to the depth of the enclosure to compensate. All volumes INCLUDE vent/port and subwoofer displacements. DO NOT change the volume unless you plan on adding a substantial amount of bracing. For added performance, applying a coat of fiberglass resin to the interior walls will greatly improve sealing the enclosure. Adding a thin layer of poly-fill will improve response by smoothing out enclosure reflections.

great subs for price

I have two of these on a hifonics brx 2400 and these mfers bang. I have had 12s,15, and many other setups and none of them have even come close to the bass i get out of these things. I knocked my rearview mirror off of my windshield and still havent broken them in yet.

Suprisingly good subwoofer

Suprisingly good subwoofer. I am usually a Rockford or Kicker person but wanted to go from dual to a single 12" subwoofer for space reasons. This was at least 5x cheaper for the same or more power handling than the brands I usually look at and I have to say I am glad I bought it. Very loud for a single 12" with the proper enclosure and very powerful and hard hitting.

Good Deal

This is a good sub for the price. I dont think there is a better deal out there. I have 2 hooked up to a 1500 amp (hifonics) running at 1 ohm. Before they were broken in I could smell them burning up a little bit so id turn em down but now they run pretty good. I think the RMS on them is not something to go by, I had a 122x mofo on this amp turned about 3/4 the way up and it blew in a few weeks. I am comfortable running the pair at 1500 watts RMS. I think 1500 watts is plenty, and at that level these subs KNOCK. I turn plenty of heads. I have played them loud and for long periods of time. If your on the fence about these subs I would buy them, get a hifonics 1500 and a you will need a charging cap or extra battery. You could easily spend twice the price and not get as much of a bang.

A lot of bang for your buck $$$

These speakers generate killer base. Supply them with the right power & enclosure and get ready to be a amazed at the performance of these speakers. Sound deadening is highly recommended!!!!

bass stops your heart

Hits hard and loud! If you like loud lots of bass?this is the sub. I was very surprised. I have a gmc Sierra ext cab and people are shock to hear that much bass from a truck. the only complaint I had to order deep mounted sub box on line...most audio places don't have deep box in stock.

Best Subwoofer So Far!!

These are by far the best subs I've ever heard in my own car before or in anyone elses actually!! I Am running two of these babys on a "Power Acoustik Demon 6000 watt " I think this is the best amp for these subs and best subns for this amp. If you are contumplation on weather you should buy the 2 ohm or 4 ohm, I would buy the the 4ohm becuase if you are running only one of them, you can wire down to 2 ohm, and if you are running two of them, you can wire both of them down to 1 ohm, which is awesome for me because my amp is 1 ohm stable and puts out 3500 watt rms at 1ohm!! Thank you so much Sonic!! I would totally recommend these subs to everyone!!!!

Blown away

I have two of these hooked up to a Hifonics ZRX 2400.1D and they vibrate buildings with ease. I have usually ran kicker and sound stream in the past and these subs hit harder and deeper by far. I figure they handle power well because this same amp burned up one of my Soundstream Reference 1's a hour after I hooked it up. I would recommend these to anyone.

Worth every penny

I had two different setups before I bought 2 mofo 124x with a 4000 watt bamf amp, and these are by far the best I've ever owned. These things turn heads no doubt. I was shocked the day they came in, when I picked up the box with the two mofos it felt like I was carrying a load of bricks. I would highly recommend these subs to anyone looking for a lot of bang without having to spend too much money. I have the pair running at 1500 RMS and don't think i'll even waste the time turning them up because they are already tearing my car apart.
