Ok I have owned all kinds of subs over the years and well this thing is the meanest thing I have ever owned. I have one at 1 ohm on a mb quart amp running 1000Watts rms. I run a dual battery set up in my jeep and I have it in a prefab Belva Sub Box 1SV12G they say it's 1.8 cubes after sub and what not thing its about 1.5 cubes woofer say it needs 1.25 in a vented box. but it sounds great during my break in period at half power I was at a buddies house 6 to 10 feet away from his garage door and we could see the door shaking. Now at full power and this thing is just crazy I know they say 900 watts rms but its taking my 1000watts rms like nothing I have ever seen. I have had other subs on this amp that clamed 1000 and they just couldn't hold it that's why I paid more for this one. I was told that dc underrates there products and I must say they are right, I feel as if this thing could hold maybe at most 1500watts rms, but at the end you get what you pay for. So just buy it and you will see for yourself this is just a great woofer and yes I would recommend this to anyone and will say i'm looking to the future already and wanting to get a level 4 or 5 from dc I am now a big fan.

Dc audio 12" level 3 sub

Dc audio has been the best street pounding sub I have ever owned.The level 3 series can handle some serious power.i currently have a Rockford t1500-1bd pushing just one sub in a Jeep Wrangler and it rattles everything around it.i am not even pushing this bad boy to its limits.i would highly recommend this sub I even picked it over a sub custom built from Psi.Sonic electronics had this thing shipped and to my door in 2days and it weighed a ton.customer service was great helping me pair it to the right ohm load as wel.Dont waste your time buying Jl audio when you can have some of the best subs for the same cost that can handle more power and sound lot better in my opinion for half the cost.these subs are competition grade.just view them on you tube to see for your self.

DC audio

I have one of these wired 1 ohm on a BE1700.1d hifonics built a box 1.25cuft after displacements tuned at 33hz in a 4th gen explorer and it puts out nice clean lows decent impact not painful to listen too and does not shake everything apart.... I bought the lvl3 with AR Cone upgrade...if I could do it again I would consider the lvl4 because my amp has about 500 more watts than this sub can actually handle .. yes its under rated

DC Audio Level 3 12 m2.1 D2

Owned dozens of subs and brands since 1990. For the money and needed wattage this thing is a beast! 850 clamped watts at 1ohm in a custom 2ft. after displacement and bracing. Only running 1 and I don't think my car can handle another. Every competition I've been in, half the field is running dc audio. Worth the price, always happy to do business with sonic too.

Exceeded my Expectations

I would recommend this sub to anyone who is looking for a serious subwoofer without sacrificing sound quality. I installed one of these in a 1.8 cu foot ported box and this sub hits all the lows! I have this put in the helm of my boat and it has the smoothest yet solid bass response of any sub I have owned. So don't think twice this puts my old Kicker L7's to shame

Nice sounding subwoofer

I replace my M3-8 with this level 3 12" subwoofer and iam glad I did. This sub sounds amazing. I have it running off a IA audio 10.1 @ 1 ohm and it hits the lows real nice. I built a custom box myself that is 1.5 qft tuned to 34 hz. I have it in a little Toyota Tacoma extra cab and it slams hard.

Very Satisfied

I'm always sceptical of products i've never worked with before but let me tell you im happy I took the chance. Before DC I was running 2 JL W3 8ohm 12's off of 2 Mclass Memphis 1.1100s. There's a long list of decent 2ohm subs but ive heard great reviews for DC. First of all you have to let these bad boys break in once they do its a difference of night and day. Strong bass. Rated at 900RMS Im running 1100 each gains set at 30%. Ported box no idea of tune. If you have the talent or money to put in correct box well worth the time and money

Best sub I've owned

I have 2 of these powered by 2 ockford Fosgate 1200d and they sound far better, deeper and louder that my Kicker l7's and Alpine type R's. They are just on a completely different level.
