General Features:

  • 12" Fifth-Generation Type-R Series Car Subwoofer
  • Power Handling:
    • Peak: 3000 watts
    • RMS: 250-1000 watts
    RMS Notification: The objective rated wattage for the SWR-12D2 Subwoofer is 750W RMS. Alpine historically labeled this subwoofer as "up to" 1000W RMS so it would line up versus other brands that at times unscrupulously overrated their subwoofers. The new R-W12D2 from Alpine (which we can upgrade you to for a limited time) is built on an improved platform, with a more efficient design and will outperform the SWR-12D2 across the board. Enjoy!

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Type-R (Alpine)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
3000 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
1000 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Dual
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
2 ohms
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
2.6"
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
24 - 200 Hz
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
84.9 dB
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
20 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Dark Gray
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Kevlar Fiber
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Santoprene Rubber
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
Optional (Accessory required and sold separately)
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / Vented
Sealed
Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.55 cubic feet
Optimum Sealed Box Volume
This value indicates the ideal sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.75 cubic feet
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.00 cubic feet
Minimum Ported Box Volume
This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.0 cubic feet
Optimum Ported Box Volume
This value indicates the ideal ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.25 cubic feet
Maximum Ported Box Volume
This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.50 cubic feet
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
6-3/8"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
10-7/8"
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

No

Electromechanical Parameters

Free-Air Resonance (Fs)
The free-air resonance frequency of the subwoofer, measured in Hz. At this frequency the weight of the moving parts is perfectly balanced with the subwoofers suspension system.
27 Hz
Equivalent Compliance (Vas)
This is the amount of air that has the same stiffness as the subwoofers suspension. The greater the rating, the lower the stiffness and larger recommended enclosure. It is measured in Liters.
46 liters
Total Speaker Q Value (Qts)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including all dimensionless losses. Essentially, a high Qts value (closer to 1.0) means the subwoofer is great for sealed enclosures and a low Qts value (closer to 0) means the woofer is great in vented enclosures. A Qts of around 0.45 means the woofer will work decently in either enclosure type.
0.44
Electrical Q Value (Qes)
The subwoofers relative damping (Q) at the resonance frequency (Fs), including electrical losses. Also called the mechanical damping of the subwoofer. The unitless measurement usually varies from 0.5 – 10.
0.47
Electrical Resistance of Voice Coil (Re)
Amount of DC resistance of the subwoofer when measured with an ohm meter. Typically, this will read less than the impedance rating of the subwoofer.
1.95 ohms
Mechanical Q Value (Qms)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including mechanical losses. Also called the mechanical damping of the subwoofer. This unitless measurement usually varies from 0.5 – 10.

Would not buy for several reasons

April 24, 2014

If you have an amp that pushes a true RMS of over 800 i would strongly recommend buying a different sub. 800 RMS or less for the money this is a great sub though..... I had this Sub for 1 day on a PPI 1000.1 amp.. it sounded great until i turned it up to negative 12 on my pioneer deck... Toast!! ... Waiting to hear from the warranty department in store credit I'll keep you posted!......

Pounders

June 9, 2014

Awesome speakers! These things pound and are often compared to rockford P3's but these are better in my opinion. Started off with three and added another one so now I have 4 of these. My power drill went through the cone of one of my subs and sonic electronix said there was no warranty against that but other than that these things slam.

January 19, 2015

The type r has the cleanest bass I've ever heard. I had a kicker cvr before and this blows it away with same amp I had. Went with a sealed box because I don't really listen to rap and perfer sq. I recomend this to anyone who want the best bang for their buck!!

November 17, 2014

i've only had alpine subs and they have never let me down, i have 2 of these and they go hard even under powered waiting for my new amp that i purchased from sonic electronix, they do handle 1000 watts rms but i wouldn't go any more than that.

Owned for a little over one month...

July 9, 2014

I purchased this sub to pair with Pioneer GM-D8601 @1ohm and 800w RMS. I ran into issues with the subwoofer's durability and ease of use. After only two weeks of low to moderate volume levels (with matched gains for Pioneer headunit) one of the manufacturer banana plug jumpers popped off. Shortly after fixing this issue with jumpers of my own, the sub would sometimes work and othertimes not. The amplifier was tested and worked fine with the same cabling, so the problem was the subwoofer.

Other gripes include the spring-loaded terminals on the subwoofer providing lower tension than I would imagine for a sub rated up to 1kw RMS. I would have preferred screw-on terminals due to the lackluster spring tension and location on the underside of the subwoofer. If you mount this subwoofer horizontally (typical install) with the "R" right-side up, the wiring hangs beneath the subwoofer, possibly shaking loose.

Overall, the Alpine Type-R is still a good value for the cost and performance, but the factory jumpers and internal components may be defective or come loose after light use. Lesson learned; I will use my own jumpers from now on. Good thing I purchased the additional warranty as the loose jumpers was not the only issue I encountered. Hopefully the replacement is better.

Alpine SWR-12D2

January 9, 2014

I have this sub wired down to 1 ohms on a NVX JAD1200.1. I have it in a custom slot ported box tuned to 33 hz with 2.25 cubic feet of airspace. This sub hits crazy hard and low with excellent sound quality. This sub also has 20 millimeters of excursion, which means more air being moved, which is up there with a lot of the top of the line subwoofers. I am very impressed and pleased with the Type R. There is no doubt in my mind that you can feed this sub 1000 watts RMS. I've had it about a year now and it's still hitting hard. It looks mean and sounds even better. The only flaw with this sub is that it took forever to break in, but I also got it in the middle of winter. I highly recommend the Type R. Excellent product!

1 Ohm or Go Home

August 14, 2013

I ran this at 1 ohm with a budget SSL 5000D amp and with my 3 farad capacitor the headlights get a little draw still when I'm HAMMERING... It makes my hairs move and the seat becomes part of the music.

I also put it in a sealed box to max capacity air space because I like rock and rap with some others around that too. If you just want bass galore then I recommend a ported box but, it wasn't my preference for my taste of music. You will need to upgrade your door speakers to match the performance and clarity of this brilliant monster.

At 1 ohm the sub slams and my amp is running cool. I don't why you would run a mono amp at anything less. Gain at 3/4 and bass boost at 0. I adjust the rest through the head unit. I could go on forever on how great every song sounds now but, you need to hear it yourselves.

If you are in the market seriously shopping... save this page and look around. You will not find a better sub for the price. Definitely a competition subwoofer. I have just one in a Jeep Wrangler 2002 and I never thought this upgrade would be this good from my Infinity 12".

Nice Subwoofer

January 19, 2015

I replaced a 10 year old Infinity Perfect 10 with this sub and am pleased. I'm still working out my gain/output settings from my LC-7 for a balanced sound with my existing system. The bass is definitely more powerful now and sounds more like when I had two of the Perfects in previous systems. I have it in a sealed box of approx. 1.0 cubic feet in my spare tire well and get good bass levels through the back seat of a Jaguar, which is pretty well padded. Construction is good and I have no issues so far.

Great woofer!

March 19, 2013

The new Alpine Type R is phenomenal and so is the service SonicElectronix provides. Heres my story:

I purchased the SWR-12D4 and shipping was very fast. With it, I also bought the HiFonics GLX 1400.1D. I wired the speaker at 2ohms giving it a total of 1000 Watts and WOW. This thing at 1000 Watts rattled my brains all freaking day. I do not recommend giving this speaker 1000 Watts unless you get it installed professionally. My type R blew after 20 hours of almost non-stop pounding (totally my fault). After I called SonicElectronix, they explained to me that you shouldn't wire it at 1000 unless conditions are absolutely perfect. I assumed the worst but here is the best part THEY REPLACED IT FREE OF CHARGE!!! They even gave me the 2ohm model instead so I could wire it at 4ohms @ 500 watts instead. I could not believe it. It says everywhere in the warranty and return policy that they do not replace blown woofers, but they did it anyway. SONICELECTRONIX UNTIL THE DAY I DIE!!

Amazing subs for great price

June 14, 2014

I have 4 of these subs running off 2000 rms @ 1 ohm and they handle it with ease and rattle everything in my car. Probably one of the if not the best subs you can buy within this price range. I've owned a lot of subs and I love Alpine products. I have also owned both models of these subs before this one and they were good too. With these you get the value of what you normally have to pay twice as much for. Great build, great sound quality and output, overall great value, and price. Would highly recommend to anyone as long as you have the amp to power them. Type R series from Alpine are the way to go.

Best Subs You Can Buy

March 9, 2014

When I say "best subs you can buy" I mean, they are the best ones you can buy at a store (with the exception of Alpine Type-X's), because I'm not sure how true it is because I've never heard any, but I always heard the best subs you can get are the competition subs you have to order.
I've had these installed for a bout a month now, and use them just about every day. They hit hard as hell and I have them under powered. They're rated for 300-1000 RMS watts, and I only have them hooked up through one Alpine amp that is 11000 watts, so they're only pushing out 550 RMS watts each (I have two 12's). From other reviews I read, many people have said only 1 of these 12" subs sound better than most 2 12" sub set ups, and I believe it.
For anyone that is going to buy these (especially if it's more than 1) I recommend buying a secondary battery (Kinetik, Reissen, Stinger, etc.), and a battery isolator (do not get a capacitor, everyone has told me they're junk).
I also recommend buying them from Sonic Electronix since they're $149.

Good Bang For The Buck!

January 6, 2013

I decided to upgrade from my 12" Kicker CVR's that I had in a extended cab chevy s10. They were really loud, but didnt quite hit the lows that I wanted.

I upgraded to two of these Type R's in a custom 4 cubic foot box tuned @ 32hz and this thing hits so low! Not even joking it makes the whole car vibrate different then highs. its a new type of bass that I experienced from these subs. they look great and pound hard, I havent exactly broke them in yet because I just got them in yesterday but so far im impressed!

I have them in a 2007 honda civic ex coupe. powered by a MTX TE801D

I have one of these running 700 watts rms and it blows everything out of the water. It hits notes my old Kicker CVR could only dream of hitting. The notes are so clear and smooth too. I recommend these to anyone.

Great sub and small boxs!!!

May 31, 2013

I have 2 that are in a 2 chamber small sealed box 0.8 after sub. This is great for rock and everything more control of the drivers for tight bass and sq pushing. 300 watts each at 4 ohms And one in a ported at 34hz .1,43cf after flared port and sub displacement I used a 3" port by 10.5 long and it slams 600 watts at 4 ohms. I like 4 ohms at less rms then 2 ohms at full rms. For the price and build you cant go wrong. I am just not sure if you want to feed them 1000 or more watts . 1/2 of that will still do you good.

August 9, 2012

Once again Alpine has done it. A good, durable sub for a great price, what more could you ask for? As soon as you open the box, you see that glossy shine from the cone. Its sleek design is sure to be an eye-catcher.

Probably the most common set up with this sub is indeed the Hifonics Brutus 1200.1D. The voice coils on these babies are rated as 500 RMS each, which adds to a total 1,000RMS, but these subs can handle more, just don't abuse them too much! Wired to the sub is a Hifonics Brutus 1200.1D, at a full 1 Ohm load. The sub hits very well, and is accurate to most songs out there. Most people think two subs are in the back, and they are surprised that its only just one! (But remember, get the proper enclosure, it does make a HUGE difference - use the recommended specs from Alpine). The sub is in a sedan. Lots of rear view mirror shaking and trunk rattling. Its been over 7 weeks now and the sub still looks brand new. To the people out there who had problems with the same exact set up, I'd hope you had a warranty so you can get a new one.

It's in a ported box, and it rattled my license plate off, cracked my taillights, and everything in the car shakes like crazy. Looks BA too.

Not very impressed...

August 3, 2012

I purchased this sub about 4 months ago. I broke it in for 2 weeks an i have it in a 1.5 cubic foot box and power it with a hifonics brz1200.1. A lot of my friends have had the past versions of the type R and i thought they were awesome, but this sub has been nothing but trouble. It over heats like crazy. I can't even get through a whole song with out my car smelling like burnt plastic and copper... It hits hard for the 2 min i can play it but after that if you feel the cone it will literally burn your hand... I never had this problem with my p3, 2 p2's or the old t1 and now I'm considering getting a new T1 cause I've never had any problems with RF. I would not recomend this sub to anyone that wants to bump for more than 2-3 min...

November 4, 2013

I bought from sonic and the service was great.Got it in time as ordered.
I had the earlier model which was captured by my son. Had it for over four years and it still thumps so I decided to get one for myself but was introduced to this one by sonic service. Best sub I have ever owned. Sounds deep and lows clear. Bought it in Dec. 2012 and no problems whatsoever. Powered by hifonics 1400 @2 ohms and just sounds beautiful.I would definitely recommend it.Saw it in VIsions for double the price. My good. Thanks Sonic.

Ridiculous Bassness! Crazy Boom! Boom!

August 10, 2012

I must say I have been researching for the right subwoofer for about a year and then came across this baby! Let's just start off with the basics. I have one of these Alpine SWR 12D2's in a custom bulit ported box hooked up to a hifonics brutus brz1200.1d amp, wired to 1 ohm.

This subwoofer has clearly exceeded my expectations. At first I was skeptic thinking that it would not be able to handle 1000 watts and boy was I wrong. It has been about 7 weeks now since I have had this sub and it still is hodling out pretty strong!

For the cost of this sub you cannot go wrong, very affordable and a big bang for your buck. The look is very simple but slick with a glossy black finish, and the durabiltiy of this sub is very well built in terms of weight and structure. Alpine, you have made me a fan and in the future I will most likely purchase another sub to make my system slap my socks off!

1000 watt RMS!!! JOKE

July 30, 2012

Ok I would like to first off state I have owned the two Type R's before this one in a 10". The last one looks very similar other than the front finish and color. When I first seen this new 2012 announced I just had to get one since it could handle another 400 watt rms! Well guess what it doesn't. I have a Brutus 1200.1 that powered my last Type R great. This new one how ever for some reason can not even handle the same power. Same amp settings, same custom built box, same car. I'm not saying its a bad subwoofer and you shouldn't get one but if you already have a Type R like I did or are expecting more power don't get it! Very disappointed in you Alpine. I may be done.

Which is awesome deal, believe me if u find them for dirt cheap id keep an eye of suspicion so please buy authorized or go sonic they offer warranties. But neways these subs hit all the notes wen tuned well nd most def put in a ported box... Id shoot for 2 cu feet. I had a pair in sealed nd they blew under pressure within two weeks. U will be happy with these subs unless u just want alotta spl for ur buck.

Very Nice

December 27, 2015

Years ago (1999 to be exact) I bought 3 JL 10W3's for $150 each. Today (2015) I bought this sub for about the same price. Inflation has not increased the price of everything!!! This sub is way better than the JL 10W3 and is about the same price. I have the sub in a ported enclosure. I'm using just one 12 inch sub. I think the sound is very nice. Hits lower than my 10's did of course (I owned other subs between the JL's and this one by the way). I am very pleased with the construction and feel of the sub. It just looks and feels very quality, durable, well made, etc. I am able to listen to fast rock and roll as well as slower hip hop and rap music. The sub seems to handle everything quite well. I would definitely recommend this sub.

April 28, 2018

These subs are crazy loud. I powered 3 of them, each with a 1000w 2ohm kenwood amp and it will tear my SUV apart if I turn it up to just 3/4 volume. Only downside is even with the subs turned to -15 on the radio they are still louder than the fronts. Had to turn the amps down to half power.

Blows anything else in this price category out of the water.

March 27, 2018

Absolutely love this thing. Upgraded from a Type S. Paired perfectly with my Pioneer GM D8601 mono amp. Puts out true 800 watts RMS at 1 ohm so don't even break a sweat (heck don't even get warm to the touch). Have it in a 1.62 cubic foot slot port box tuned to 35 hz. Come summer I plan to put it in a box that is the exact recommended size but tune to 32hz. 35 is great, but really drops out on the low notes. May try a few different to see what works best for me.

Pros:
Hits way harder than comparably priced subs on the market
Very clean construction love the new look
Very versatile in adding to your set-up. Comes with nice jumpers

Cons: (Not much)

I use 8 Guage power wire as my speaker wire. On my Type S the terminals readily accepted freshly stripped tightly twisted 8ga without needing a lug or banana clip. The jumpers sat firmly in the top of the terminal with the terminal remaining 90% depressed due to my choice in large wire. On the new R it handles it but stays about 98% depressed and the included jumpers barely stay in. When I do the new box I plan to use some type of lug or clip maybe a dual 8ga to single 8 lug and replace the jumper all together with an 8ga power wire jumper.

The included jumpers claim to be 8ga but are more like 9ish and the clips are not as sturdy as what was included with the type s I have. Nothing to whine about just make sure you pay attention and if you unplug them ever take the time to spread them out again so they seat properly once again.

Lastly not really a con more of a compliment but being it's my only sub I wasn't expecting having to reattach my rear view mirror because this thing shook it off. Also needed to place a clamp on the stem of the rear view to keep it from pointing at the floor.

Blows anything else in this price category out of the water.

March 8, 2018

The following review is for R-W12D2, which is a part of the bundle you are viewing.

Bought this to replace my 1 year old Type S. My daily driver is a 2007 Chrysler Town and Country (Hey I got kids and they haul crap). I just wanted a little more than what the S was giving me. Got way more than I had hoped for. I thought I would get about double the sound. Nope its way more than double. I have this matched to a Pioneer GM D8601. Puts out (True) 800RMS @ 1ohm. Installed it today and got it set up. I dont do the break in ritual some people live by but I do take it easy for the first hour. Then retune and go all out. I must say for 1 12 in a 1.5cuft slot port in the back of a minivan sounds like I got way more than what I do have. Got a buddy at work work running 2 12' JL W3s and I cant wait to run the db meter with him to see how this compares. I know vehicle makes a difference and box but hes got those in a Tahoe in slot ports and they dont hit as hard. So heres my Pros and Cons....
Pros:
Way under priced (For what it is should really be in the 350+ range)
Very well built
Love the new look
Packaging is solid
Puts out way more than expected
Comes with jumpers

Cons:
Only 1 The included jumper wires.
I run 8ga speaker wire. Why? Mostly because I can, but I do notice a difference in responsiveness and also amp runs way cooler. But that being said the included jumpers have cheap banana ends on them. When I put the 8ga into the push terminals it makes the banana only go half way in. Was a little worried about them popping out so ended up using the set that I had from my type S that seemed a bit sturdier. Plan to rework inside the box and just make my own jumpers to eliminate the potential problem.

Great Buy!

June 6, 2016

I only put one sub in my Subaru STI and it was plenty bass for me. I was just looking for a little thump and these delivered. I don't even have the amp turned up past a quarter of its potential and it still rattles things off the walls inside my garage. These are clear and sound excellent! I would recommend these to any one.

This is the second set I've had. The first lasted 3 years until my amp shorted and caught fire sending a power surge blowing the old ones. If my amp didn't fail these subs sure would've lasted a lot longer. They hit very hard. I've blown the rear hatch window right out of my crx while going 70mph down the highway lol. They almost hit too hard. Great subs at a decent price

Finally put it in

May 20, 2016

It's a nice speaker. I got the 2 ohm and didn't realize with duel voice coils you can make them 4 ohm by series hook up or 1 ohm parallel. With a 2 ohm stables amp I have to run it at 4 ohms. The only way to get 2 ohms final would be adding another 4 ohm final and parallel them. With only 1 sub I should have got the 4 ohm to get 2 ohm. It's misleading could have been clearer. Not a big deal I have s huge 1200 mono giving me 700 at 4 and it's plenty. I still could tweek amp and crossover settings but it got realistic 12" sound. I would like to get more puch but don't except this to do that I am getting other systems going hopefully for that. Added the matching alpine 5 1/4 component today running off the head but have an amp to add to them. I probably would have gone 8 or 10 but the price for this was hard to pass. I'm not a big booming bass fanatic but like to have kick. Why lie bass pedals on Genesis Dance on the Volcano is awesome Song choice amp and settings make a difference with final sound and this sub is sounding versatile. Trying to get George Benson Breezing to audiophile quality in my Saab 900 S. S could be for Sonic now. Having changed out from a Bass Link it's 100 times the bass and 100 times cleaner. I would have to directly compare it to another similar sub to have more of an opinion but I'm pleased with it alpine is a name I am familiar with. Don't think you can go wrong with this if you have room. It has a big power handling cap and a big amp on it. Woo I added the Alpine matching grill too.

Alpine SWR-12D2

April 1, 2016

I bought two of these babies, along with a Kicker KX1600.1 (1600 watt) amp. I built the fiberglass sub inclosure (3.23 cubic feet, for both subs in one sealed box, "fighting one another"). "Bad to the bone" does not even begin to explain the awesome sauce that these babies force out! Get this setup, and your next problem will be, trying to pad your vehicle, so nothing rattles. If you want to be heard, and I mean crisp and clear, there's no doubt about the fact that these SWR-12D2's are the ticket! This is a GREAT price, for the product! When shopping for the components, for my system, I was looking totally for the most RMS power handling ability. 1000 watts, per sub, is AWESOME! Just shop around, if you don't believe me.
