Alpine's Type-R subwoofers will bring big bass to just about any vehicle. The SWR-12D2 12" sub features a cone made from Kevlar® treated pulp — the same material used to make bulletproof vests — and its durable HAMR Santoprene™ surround allows for huge amounts of excursion. This sub was built for bassheads that want the best of both worlds: accurate response and otherworldly thump.
The SWR-12D2 can handle an astounding 1000 watts of RMS power, so be sure to choose a suitable amplifier as these bass monsters definitely want lots of power. Its dual oversized 2-ohm voice coils offer the wiring flexibility you'll appreciate as your system changes and grows, so you can always pull maximum power from your amp. It works well in sealed and ported enclosures so you can choose what kind of bass you want to hear and feel.
Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible.
To drive this single subwoofer, we recommend a mono amplifier rated between 750 and 1500 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Average Customer Review(s):
Just installed this in my 2015 WRX with a Pioneer GM-D9601 at 1 ohm. Very impressed. Nice clean bass.
Pros: 1000 watts rms. Solid and rugged design.
I listen to a ton of bass heavy rap and VERY bass heavy dubstep and this sub works amazing. I like being able to still hear my music obviously so two of these bad boys is just way too much for me. One does the trick if you want good balance. This sub still shakes the heck out of my car and hits the low notes like a champ. Absolutely no complaints about it. Fantastic product.
Pros: hits low notes very well, shakes my car, good balance with just one sub
Yeah they sound good and all but th definitely can't handle 1000w rms or even close. I had a perfectly compatible amp and these professionally set up and they keep giving me problems. I blew two of them. And the two new ones I have in are having issues like the one heating up to the touch it's ridiculous
Love the subs !! Bang for your buck
these look awesome and sound even better. my son is very happy
Pros: very well built sub
Cons: no yet
I purchased two of these and I can say that it was money well spent. I am currently running these with a Kicker KX 1600.1. They are in a sealed box, 1.25 cu. ft. for each and they Slam. Now I heard on a lot of forums that these wouldn't sound great sealed and that they were only great performers in ported boxes . Dead Wrong. These have great SQ, hit incredibly hard and still make my license plate and trunk rattle even after it being dynamatted. The bass is incredibly clear, deep and rich. They are extremely versatile as well, proving themselves useful from Metal to Rap all the way to techno and pretty much anything in between. Do yourself a favor and if you are serious about your bass, Get These! They are a steal at this price for the performance you get. A big thank you to Crutchfield as well for the amazing customer support!
Pros: Clean, deep and hard hitting bass, incredible accuracy, LOUD
If You don't Rate these 5 in every category, then you probably didn't hook them up correctly. Or didn't put them in the proper box. I run them off A Hercules Brutus 3000 watt Rms amp and they pound harder than I can handle. The proper tuned enclosure makes a huge difference also. Second best sub on the market. I think we all know whos first. Two type R 10s or 12s are way more than the average bass enthusiast needs. Of course, they must be wires properly to a big mono amp
Pros: Solid, powerful, Alpine quality, great bang for the buck, and pretty
Cons: Needs proper enclosure and not for sissys
The best sub I tried to date
Pros: worth the money
Love these subs! I was rocking the previous gen 1223 d's and with 2200 watts going to them, they have been falling off. When the first went, replaced with one of these guys. Now the 2nd one failed horribly, I now have two of the 12d2's Been able to turn my gain up almost a 1/4 turn and have been loving it. Have them in a 3.5 cu ported box. They do great with metal, rap, and when I'm in the mood, a little country. Really impressed with metal! Double kicks have almost no slop at all.
Pros: Price and power handling for the price.
Cons: Sometimes the jumpers for ohm selection don't feel secure. Put a dab of silicone on them and all is good.
I purchased this sub to replace a much more expensive sub that was taking up too much room in my trunk because of the size of the box required to hold this ferocious sub. I had doubts as to whether the Alpine could match the performance of the old sub. I must say that I am pleasantly surprised to report that the Alpine is probably presenting at least 90% of the performance of the old sub which cost three and a half times as much as the Alpine. The old sub has performed flawlessly for over ten years. If the Alpine can perform as well for that long, I will be very satisfied.
Pros: Solid, well constructed, handsome and very good performing subwoofer.
Cons: None to mention yet
So excited to get these two subs in my hatch Back!
Bought a pair of these off a friend and I only run them with a tiny 250w amp and they still pound really hard. They are about perfect with a 600w though.
Pros: Look amazing, great sound.
Cons: pretty heavy, especially paired in a box haha.
This is the mother load....this speaker has the deepest bass of any speaker I have ever owned. It take a good sized amp to run it but you will be more than satisfied with your purchase.
Pros: Clear deep bass, great design, cool logoing, and clear instruction for various uses.
Cons: Needs a large amp...power hungry
My first amp was an alpine 500 watt which worked really good. I then wanted Moore so I go 1000/1 jl audio amp and its insane. One is all you need. I had a w6 jl 12" and this one has it beat and half the cost. Alpine pounds on. 10/10
Pros: Perfect hard hitting bass of any type if wired and. Paired right
Well for being a 1000 rms and 3000 max sub it does not handle power well. I had a 2500 watt amp and heard voice through it so I sold the amp and got a DC 1.2k wired to a 1ohm the amp pushes it hard and sub heats up quick. Now before I had this sub, I had a Kenwood performance and I felt it hit harder at a 600 rms and 1200 max. If I could take it back, I would.
Pros: Easy to use, just plug and play
Cons: Heats up quick and doesn't hit as hard as you think.
I think they look SWEET! Listened to them at the local sound shop and they are clear. They look very sleek!
Pros: Look great!
Cons: A little pricey.
Look good and sound better
Pros: Hits hard for the $$
Cons: Haven't seen any so far
Sounds great paired with a Memphis amp
Running 1 Type R on a JL J21000.1. Sounds great, a big improvement over last year's model.
Pros: Can handle more than enough power for a medium duty system. Woofer feels very sturdy.
Cons: Not for the larger ported SO sub box.
I've swapped in and out pairs of cheap ($30) and middle of the road ($60) 10" subwoofers and I even gave Pioneer's top model 12" a try but none of them has made me happier than this subwoofer. It has always been a trade off between bass and space in the past. 2 10s in a 2 cubic foot sealed or a 3 cubic foot ported box. Now I've been getting the same output from one 12" in a 1 cubic foot sealed box. Lately I've built a ported box tuned to around 32 hz and it has even better output. Now the bottom note in Young Jeezy's: Put On has become not only audible, but vibrates the seats in my full-sized sedan. Even though this subwoofer is extremely loud, it is not a "kiddish" or "childish" thing. This subwoofer produces well-refined, accurate, and detailed sound that will give your vehicle a real luxury feeling when you listen to it at low volumes. And of course, when you do feel like letting everyone in a parking deck know you're there, you can.
Pros: Loud when you want it to be. Deep, soothing sound at low volume. Small box size. Requires very little power to get a lot of output. Good looking.
Cons: The grill to protect it is expensive. It weighs 30lbs. Not that I have a problem with that. Just trying to find something negative about it.
This is an amazing subwoofer, but if you wire it incorrectly or under-power it, prepare to be underwhelmed. Of course that goes for all subs though. I do recommend a bigger box than the specs provided by Alpine. I built a box to their specs and it sounded great. Then to increase volume inside the box (as an experiment) I inverted the sub and got a drastic increase in SPL. I'm not necessarily recommending inverting, because I feel like my sub is to exposed, but I do recommend at least 2 cubic feet inside a ported box. And that is not counting the port or subwoofer displacement. Of course tune it how you like, but I do not feel like I lost any SQ with the added volume. In fact I feel like I gained some on songs that do not have much bass. One of these subwoofer **properly powered** is enough for someone who wants excellent sound quality, with the capabilities to get loud when they want. You have to plan for the future also. If you plan on having 2 of these, be sure to buy the 2 ohm version, but if you are going to stick with one, I recommend the 4 ohm version. That way in the end you will have 2 total ohms and will be able to get the most from your amp
Pros: Excellent SQ and SPL Can get loud, but also doesn't sound bass heavy on songs that are not bass heavy.
Cons: Requires a little knowledge of impedance. But no worries! Crutchfield is here to help!
I bought this sub just under a year ago and I cannot be happier with it. I knew I wanted one for a long time but I could not decide on which one to get. I decided to get one sub with a 500W amp and I am not at all disappointed with my purchase. I use it every single time I drive somewhere. Having a sub like this made me appreciate certain kinds of music more because it adds a whole new element to the beat and song. When I crank the volume it is a massage.
Pros: Hits crisp high and low frequencies. Better low's than friends 2x JL W3.
words cant describe this sub. i had one 12 inch type S and liked it but cold weather got to it and cracked the surround so I upgraded to 1 12 type R running off a alpine mrx-m110 amp with all alpine type s 6x9s in the vehicle and with the amp only runnin half power and the deck at -7 for bass the sub still overpowers the 4 speakers. It ratteled the windshield so much the seal on it broke. The Break in period did take about 30 to 40 hours but it really hits every note clean and can hold the bass no problem. Alpine is definately in my mind and others who have heard my system the best audio company out there with reasonable prices for their products.
Pros: just incredible, strong bass, loud, clear, crisp, hits every frequency, awesome
Cons: heavy haha, too much bass
These are the best subs Ive ever had. They hit very hard with no distortion and the sound is truely amazing. Very cool having the cooling hole through the magnet to the VC. I recommend these subs to bass heads who love serious bass without distortion or breakoff. Worth every penny!! Thank you Crutchfield for awesome fast and safe shipping of my subs.....kodos
Pros: great looks, great sound, decent price for what you get.....and we all know you get what you pay for :)
I have a pair of alpine type r 12s in a ported box in the back of my 2003 mazda protege5. (hatch). hooked up 2 ohms to a 1000w alpine amp (last years model), only pushing each at half of the capable RMS, and these things quake. they have already made my rear view mirror out of a function. even side mirrors shake. At only 25/35 volume they out weigh my mids and highs by far. if youre looking for a set of QUALITY subs that are made to last and bump, go for alpine. dont go with kicker or some other crap. i out beat my buddies 3x type e's to a 4000w cheapo amp. both of us have the loudest bang around town though. these are really good buy.
Pros: quality reliable tight tuned
Cons: i blew my type s's so i upgraded to r and have had absolutely no problems.
With a growning family I had made the choice to retire my 2 12" infiniti kappa subs and replace them with a smaller 10" sub so I could reclaim some trunk space. I am running a Profile AP2000 960 watts RMS @ 4 ohms & a Kenwood DNX 5120 head unit. I chose the Alpine SWR-10D2 as it seemed a very good choice and could handle the power my amp puts out as well as it was a smaller sub. I had that sub for almost a week it packed a really good punch but was leaving a some to be desired so I did some research and decided the 2 inches each direction of box space and an additional $50 would be well worth the investment if I could get the depth back in my music that I liked having. I do not regret the choice at all this sub hits every bass note in every song I could throw at it. Most of which it hammered great with the sub output on - 16 (Negative). I haven't had to turn the sub out on my head unit past -10 (negative) for any music type. This thing is insane!!!!
Pros: Ample power handling, Very responsive to all music types
Cons: None that have been found yet unless to loud for the nieghbors is a con
This sub is amazing, I only put one in my '02 Expedition in a custom ported box powered by the Alpine M110 amp and it hits HARD. Amazing value for the sub at only $250.
Pros: Looks great, sounds great, hits hard as hell.
This subwoofer is going to be the best subwoofer alpine has sold by FAR.

Kevlar Reinforced Pulp Cone: This Alpine Type-R subwoofer has a two-piece structural parabolic Kevlar reinforced pulp cone. Kevlar adds strength and tear resistance to the woofer cone while maintaining the benefits of a pulp cone design. There is also an oversized inverted poly-mica dust cap, which increases rigidity and virtually eliminates cone distortion at extreme volume levels.
HAMRS: The woofer features a High Amplitude Multi Roll Surround (HAMRS), made of Santoprene, that allows a large linear excursion and greater SPL. The HAMRS design allows extreme excursions without sacrificing valuable cone area.
Progressive Spider: The progressive Conex spider has reinforced layer tinsel leads to ensure reliable and consistent control of the tinsel leads and eliminate any mechanical noise or interference often seen in high excursion cone designs.
Compound Radius Curve Pole Geometry: Alpine's Patented Compound Radius Curve pole geometry ensures a symmetrical magnetic field, while optimizing flux density to reduce distortion and further improve power handling and output.
Oversized Voice Coil: The oversized (65mm), high-temperature, 4-layer dual voice coils offer increased power handling to 1000W RMS / 3000W Peak.
Dual Voice Coils: For system flexibility, the woofer has two 2-ohm voice coils. When the voice coils are wired in parallel, the woofer presents a 1-ohm load. When the voice coils are wired in series, the woofer presents a 4-ohm load.
Spring Terminals: The spring post terminals are all located on one side of the woofer. The terminals will accept bare wire up to 8 gauge, pin connectors, or banana plugs.
Jumpers: Included with the woofer are two voice coil terminal jumpers. These jumpers allow you to easily wire the voice coils in parallel (for a 1-ohm load) or series (for a 4-ohm load).
Sealed Box Volume: The recommended sealed box volume ranges from 0.65 cubic feet to 1.1 cubic feet, with 0.85 cubic feet being the ideal size.
Ported Box Volume: The recommended ported box volume ranges from 1.1 cubic feet to 1.6 cubic feet. The ideal size is 1.48 cubic feet, using a slot port measuring 12-1/2" (W) x 1" (H) x 19" (L).

Alpine is a quality brand and i prefer quality [ Terrence Jun 25, 2017 ]
A lot of good reviews [ Billyjoe Jun 22, 2017 ]
It has the best bass you can get. [ Danny May 03, 2017 ]
Slams! Gave it 1000rms daily no sweat [ Maximilien Mar 03, 2017 ]
They had good reviews, I upgraded to 12" subs from 10" subs, I have always liked 12's and Alpine did not let me down. [ Benjamin Sep 22, 2016 ]
The reputation of these subs and because their user manual supplies more of the needed T/S parameters unlike some other brands. [ Mark Jul 07, 2016 ]
Great quality [ Michael Jun 01, 2016 ]
Proven quality speaker [ Mark K. Mar 09, 2016 ]
No it does not include those but I found it better to play around with the size for better sounding subs for your car size [ MARTIN J Jun 06, 2017 ]
You should be fine. I have ran mine on dual channels but never for extended time. I run my d2s at about 1700 with a mono block and have had no issues for 6 months on my daily. I recommend buying an amp better suited for the job though or you'll never see the full potential of these awesome subs. [ joshua May 29, 2017 ]
I'm running roughly 900+ watts @ 2 ohms to just one of the two alpine 12d2s I purchased and it sounds excellent. However you're running roughly 200 watts less than the recommended 1000 watts rms. So you may have slight distortion. Stick to the 75-150 percent rule and you'll be fine. [ Roger May 26, 2017 ]
It's best to wire it so that it's at 2 ohms. Google how to do it or find a person who knows what there doing. I know that you need to wire the sub so it works well with the amp. They need to both run at 2 ohms [ Lukas Apr 24, 2017 ]
Just use one side of the alpine subs terminals. since it is dual voice coil. Just pick a side [ Fast Apr 21, 2017 ]
Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Krissy May 16, 2016 ] Staff
Thanks for your question. This is for one 12" Dual 2-ohm voice coil subwoofer. Hope that helps. [ Kenny Apr 11, 2016 ] Staff
I'd highly recommend keeping it low for around 50-60 hours of playing time to let the subs break in. The difference between out of the box and broken in for me was extremely noticeable. How many amps is your amp rated for? [ Taylor Nov 17, 2015 ]
The dvc should be in series, and then the subs in parallel in order to get a proper 2ohm load on the amp. Double check the wiring to make sure it's the correct set up. There's diagrams on crutchfield's website. Those subs can handle way more than what that amp can produce. Make sure you don't have any bass boosters enabled on you head unit. They can overload your amp input and distort output. Keep the gain/bass knobs on minimum setting. You can set the freq knobs to your liking. Increase the volume on your head unit until your main speakers are loudest without being distorted and turn it down one or two notches. Now do the same with your gain knob on the amp. And then bass eq. [ willie Nov 17, 2015 ]

since you're looking at the dual 2ohm voice coils you can only run that @ 4ohms with that amp otherwise you'll blow the sub if you attempt a 1ohm connection. i recommend getting the SWR-12D4 and running it at 2ohm giving it 800W [ GERALD Jul 10, 2015 ]
Sure will. Wire the voice coils in parallel and you'll get the 1ohm from the amp. I'm sure the sub can handle the 1200W, but of course they're only rated for 1000. [ willie Jul 06, 2015 ]
The best way to get your answer is to call Crutchfield Technicians. I really don't know what a r1000-1d is, so check with Technical Support. [ David Apr 07, 2015 ]
Yes this should work Because u want to keep 2 ohm stable so u may need more power [ Cory Apr 07, 2015 ]
i have that exact amp and blew that exact sub twice with it at 1ohm. DO NOT attempt 1ohm connetion on the 12D2 with more than about 400W max rms. i now have the SWS 12D4 and running 500W from that same pioneer amp @ 2ohms in a single sealed box in the back of a 92 oldsmobile. it shakes the car. virtually no problems [ GERALD Jul 10, 2015 ]
It says 3000 watt peak so you should be fine, I have mine in a ported box at 1200 watts, you can't tell its only one speaker , very loud. [ DeAnn Mar 17, 2015 ]
U can run it but u would be under powering it so u should get the sub and douwn the road upgrade to a bigger amp [ Chris Mar 11, 2015 ]
Yes, you can the sub can handle that, no problem. I was running a 1200 Rms dc amp and pushed really well. Just make sure that you break in your sub properly before cranking it up, it took me about 2 weeks at half power to make sure the coils set properly [ Frankie Mar 10, 2015 ]
You may blow the speaker. I had an alpine mx1100 at one ohm and blew in 30 mins.. Now have it at 4ohms [ THOMAS Mar 10, 2015 ]
Yes. You'll have to wire the voice coils in parallel to get the 1ohm load. [ willie Mar 10, 2015 ]
I have a rockford fosgate 750 watt amp at 1 ohm to each sub and they sound very good [ ALEJANDRO Mar 10, 2015 ]

it depends on what impadence you plan on using. if u set them up as 4ohm jumped and seal them together with one resistor in the back of the box you can run alot of power @ 2ohms. so look for a mono amplifier that has an RMS of 1200 or higher @ 2ohms. thats how I would do it. [ GERALD Jul 10, 2015 ]
