I originally ordered one of these 2ohm subs for my wife’s Nissan and I loved it. I ended up buying this 1ohm sub for my truck and I have it wired 2ohm and have the harmony sound box as well. I have an nvx nda104 3k mono block powering this sub and it delivers great sound and hard clean bass. The cone and dust cap are carbon fiber and stitched and rugged. The box and sub weighs over 100 pounds,fyi so if you’re just looking for a basic sub keep moving. This sub is power hungry either feed it the power it needs or don’t waste your time. I broke my sub in at half power for a solid two weeks and it’s been perfect since. I’ve had numerous other top brands and cheap china garbage and this sub is beyond worth the money and makes other top brands look really bad when the price comes to play. Again this is not a beginner or just a small upgrade subwoofer. If you by this sub know it’s 3k watts rms it requires a suitable amp and an amp powering range his sub is gonna draw at least 100 amps and it’s going to require the big 3 upgrade, a second battery and isolator and by all means not a cheap wiring kit. Zero guage is a must. With that said if you don’t plan on all of that don’t buy this sub because you will most definitely over work your amp because it will be starving for power and that will send a clipped signal to your sub it will get hot and it will destroy your sub your amp and if your fuse doesn’t pop it will definitely melt an under sized power wire and probably start a fire. I have close to 3100 watts of clean power going to this sub and it can take more no problem. If you are a bass head this sub destroys a lot of other brands on the market and is worth every penny and is equivalent to the exo line from ct sounds but half the price and all of the power and quality.

These are some serious 12s. I also have the monolith 18s. You won't be disappointed. I won't name bash on here but I can assure you I've owned very very well known brands but those brands are a serious let down after getting these bad boys . All brands have to start from the bottom. They offer product at a discounted rate . Then they let the product speak for itself. The monolith subs and Harmony Audio amps in my opinion will be the next big name in car audio. It's just a matter of time. Im sure after this happens the prices will definitely go up. I would get them now while pricing is low.

I wrote a review a few months ago when I first got one so now is the 6 month update. I love these bad boys!!! They def hit hard has hell in every box I’ve put em in. I’m doing a custom bench in back of my f150 with 4 of these and two hifonics colusses 6000 watt amps. I’m jus waiting on my other sub now and it’s going in. I can’t wait!!! But def worth the money compared to sundown and dc audio. It was a toss up because I heard Skar is good to but I went with these and I’m glad I did. Very sturdy construction good motor nice stiff sub but not to stiff and spider is big so it flexes more than the others.

Running on 2 channel. With a 3rd 750 watt alpine bass. Wakes up the neighbors just fine 😎

I was very indecisive about this sub because it was not a well known name brand and had no videos or not very many reviews. But I took the chance and this thing is amazing had it about 3-4 months and it hits hard every time needs a lot of air has beefy high temp voice coil with black glue huge motor and nice kinda stiff surround I have it on a 1800watt taramps turned all the way up and it sounds amazing
