Loud and clean just buy it!!
I''m running one of these on a Hifonics bx1500 at 1ohm in a custom birch box built to specs and it flexes my whole car and plays LOUD I''m in love with this sub and I tried a few others before like Kicker, Rockford Fosgate, Pioneer, and JBL but they just don''t even compare. This one keeps up with $300-$400 subs for just under $200. I would never buy any other brand in subwoofers again besides soundqubed. Thank you soundqubed for awesome products at affordable prices and awesome customer service.

Knockin!
These put my previous SA-12s to shame. More musical and digs down deeper! Have two of them in a 5 cu ft box tuned to 30Hz. Underpowering them atm running a Q2200.2 but properly tuned with a DD-1. Still sounds amazing. One month in and they''re probably not even broken in yet. One thing I noticed on these is that the tinsel leads are MUCH more solid than the SA-12 (I fried my SA-12s tinsel leads). Can''t wait to hear these after they''ve broken in, and eventually get a Q4500 to power them xD

Best 12 I''ve owned
What can I say, excellent woofer. People think I have 2+ subs and they''re surprised when I just have one 12. If I had more room for a bigger box, I''d buy another one in a heartbeat. Best subwoofer for the money on the market.

HDS312''s
Just installed mine this weekend in a 4.91 cubic foot enclosure in a 2000 Ranger EXT. Ported box tuned at 33 hz. These things are amazing! I replaced 2 alpine Type R''s and the Sounqubed''s blow those away hands down! Running them on a PPI Black Ice 2600.1 at 1 ohm. I am not looking at switching out my components for Soundqubed''s as well. Tech support ahs been great with my numerous questions on box sizing, port sizes, tuning etc. Great work !

If your thinking of buying it just buy it. This thing slams in a 2.5cubic box and loves the lows.

Amazing sub
I bought one of these about a month ago and put it on a hifonics Brutus 1700.1d as a daily at 1 ohm and it bangs while handling the power nicely. It does get warm after bumping at full tilt for 30 min but since I am overpowering it, it''s amazing I have it in a 4 cubic foot box tuned to 32 hertz and smashes the lows.

Awesome Subwoofer
I purchased a Sundown SA series 12 through Amazon and paid about $60 more. I was thoroughly unhappy with the SA-12. It was an awesome subwoofer, but to make a long story short I believe the subwoofer was a factory re-cone job with rookie mistakes made. After failure of mechanical components, I bought the HDS312. This subwoofer definitely gives the SA-12 a run for it''s money. In the correct box (some prefabs are alright) this subwoofer will blow away the competition. For a daily driver, the HDS series is the one to get; it is definitely loud, and has excellent sound quality for the price. I have had several different brands in several different vehicles, but I now believe Soundqubed to be at top of my list. Also, shipping was awesome for a southern state such as Texas.

HDS312 Subwoofer
Before I had two JL Audio W3V3 10" subwoofers and to me at the time those were loud! But I never really got the SPL I wanted and let me say look no farther if you''re under 1500rms. This subwoofer is perfect and can handle tons of power. I currently have a Soundstream rubicon 1.1000D hooked onto a D2 model HDS312 and it slams really hard. I had people asking me at automotion 2016 if I had two or three subs in my car. It is everything you''d expect it to be. Also one thing I''d like to point out is if you decide not to buy the attrend enclosures, to not be afraid of other 12" subwoofer box''s. Anything with a cutout diameter 11" and up will fit the subwoofer. Hope this helps anyone deciding on a subwoofer.

Subs should of been called MONEY!
I have been selling car audio for about 3 years now. I have seen hundreds of different makes and models and lots of different price brackets. There is no doubt in my mind that the hds312 is by far the most bang for the buck. You will never find another sub under $200 that will put perform this one. It takes a crap load of power. Sounds amazing. And looks and feels awesome. Soundqubed should start a "subwoofer challenge" challenge other manufacturers to bring forth a product that can take more power and for longer than the hds312 and sound as good while doing it. I bet other companies coward to the challenge!

Mr.
I bought two of the to replace some type r''s that I kept going through like they were socks, got each one running at 2 ohms on 2 Alpine mrx-m110''s @ 1100w rms. They sound really good, they hit way lower than the type rs did, I do how ever need a Q1-4500D.1 for these subs.

This one 12 outperforms 2x12" Kickers, and shakes the earth with such finesse. Picking SQ over a Best Buy brand was a no brainier. If you''re doing anything right, this sub should tear apart any pre made box. Build your own.

Bmw 540i DSP with Alpine PDX-1000, 2x HDS 12 SQ
Still breaking in the subs, spider is super tight. Sub coil is well aligned and glued correctly. 4.4 cuF ported @ 38hz to match level for DSP amp levels. Fill the void spots that stock subs could not like a champ.

HDS3 Single 12
I recently got one of these beasts last month, got it for my birthday. I have this just one of these paired with a Lanzar Evolution 4000 Class D Monoblock amp wired to a final 1ohm load. Sub is seeing 1430 watts RMS from the amp at this impedance. It is housed in a 4th order box tuned to 40hz. Let me tell you this thing slams harder than my buddies mofo 15. I haven''t had it metered yet, but people I give demos to say that is the loudest single 12 they have ever heard. If you are questioning wether or not to buy this stop epculating and BUY IT! May eventually get a second one of these beasts! 10/10

Mr.
All I can say is "WOW"! These speakers are amazing and were far above what I expected when I purchased them and had them installed. I order two HDS312''s and had them connected to my 2500 watt rms amp and the bass is powerful, deep, and highly responsive. These speakers are sturdy and built with quality. They can hang with any other 12" sub regardless of the price or brand. I am a die-hard Soundqubed fan for life now,and I plan on only using Soundqubed subs in my vehicles. Thank you Soundqubed for an amzing product!

What an incredible sub!!! For the price and the quality of the build, this is a wonderful speaker. Warm, punchy, and just flat out powerful. I looked all over Amazon for a sub that is under 200 bucks, and the listing were just mediocre speakers. But from a competition level company delivering this speaker for a budget... HECK YEH! I am loving the sub in the cab of my truck. Thanks for the great customer service too!

SoundQubed destroys the competition
I''ve got two of these in my 2002 Ford Mustang. These things pound! I''m running them with the 1200 watt SoundQubed amp. Definetely going to but the Q1-4500 watt amp soon. I recommend these to anyone that wants to do some street competitions. I went to one and pulled a 134.5 decibel reading! Everyone asks me about them and says that my car is so loud. It shakes the chandlers in my house! Love SoundQubed and would honestly never go to any other company. Extremely satisfied with my purchase!!

SQ HDS312 D2
I purchased this sub in January, took 2 months to get built and shipped. The quality of this sub is excellent, rivaling much more expensive brands, and packaged well with hard foam. I have the D2 model on an American Bass 1600 RMS amp, and it can take more. Handles the lows very well tuned to 33hz in a 1.75ft box. I reccommend to anyone that wants an inexpensive woofer to handle high wattage!

I had 2 pioneer 12s and decided to build my own box and go better subs. I follow soundqubed on YouTube and looked online. Decided to go with the Hds312s. Great price and they hit so hard. Play a few demos for people and they can''t believe I only have 2 12s. Don''t hesitate to get them!

This sub will amaze you. I previously had 2 12 inch kickers i got for free and this blows then away. When the bass hits i can feel everything inside me vibrate. The only true way to explain it is that this shit bangs. I''m pushing it on 1200 watts from a kicker amp no problem. My only complaint would be that the screw holes were pretty bad to the point they''re basically covered, luckily i could just barely fit the screw threw. Not sure how that got past qc

Awesome Sub!
I could not be happier with this sub. I replaced a Hertz High Energy sub with this one and it hits harder, plays a wider range of frequencies and best of all, was a fraction of the cost. It is constructed well and looks good too. I am running it 1 ohm to my DD-M1C and am very happy.
