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.
4 ohms
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".
85 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.
0.65 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.
1.25 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
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.
2.0 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.
10-13/16"
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.

Don't be fooled

March 30, 2014

Alpine say's that this sub will run 1000 watts. Don't be fooled I Bought one and blew and 3 months after the break in period I blew a voice coil. I had it hooked up to a JL Audio 1000/1 V2 slash series amp. The sub is worth the money if you're not gonna run 1000 watts to it but if you are you might want to go with the type x.

January 31, 2015

I've had previous Alpine Type R 12" speakers, and purchasing their most recent version from Sonic Electronix was good move! Great product for way less than you'll pay anywhere else. I'm consistently impressed with Sonic Electronix 's product selection and shockingly low prices. I will continue to support and recommended this Company.

I want to ask someone who really have owned this new type R and owned a type x also, I had bought a type R in 2009 and it wasn't loud so I changed to a type x, I am wondering if this new Type R is the same as a Type X since as they discontinued the Type X?

May 16, 2014

I have had dual Rockford fosgate p3 12s and dual hifonics Brutus sq 12s and neither compare to these sub's. You can not beat the price and quality of sub's. Must buy!!!!!! Only issue for me is the extra rubber that hides screw's. It would stay on so I didn't use it but they still look and sound beautiful in ground shaker bandpass box.

Alpine type R

February 11, 2014

This is a great subwoofer, for 159$ this and the RE audio line, are the best for the price. I chose alpine however for the significant power boost. Just so you guys know you really don't have to worry about power, just watch your gains. I'm giving mine 1200 rms and it takes it like a beast. Highly recommend this in a sealed box for rock, and really it gets to a great volume in a sealed, but ported for sure if you're into volume and you will only need one of these.

Alpine Type R SQL

November 9, 2012

First thing I notice was the tightness of the cone. I switched from CVX to these. I had 1732 real rms watts on the CVX's I have a new amp putting 1949 REAL rms watts to these bad boys. They sound so good. I 20mm of xmax, they catch all the notes that the CVX's missed. Alpine really out did themselves with these subs. They even match my trunk's carpet. My buddy has two T1 12's on a T1500CP and my systems is louder than his. I metered at 148.2 and he hit 143.6. Not bad for Type R's.

Don't like seeing the hate on these subs about overpowering them. List the amp you have pushing them and the settings. I have an NVX JAD 1200.1 powering 2- Dual 4 ohm 12's. My electrical doesn't support it just before clipping. Backed it down just a little and voilą. There you have it. Haters quit hating and adjust your amps correctly or pay someone who knows what they are doing to do it for you. Damn good subs. Highly recommend.

Surprised!

February 1, 2013

I was doing a lot, and I mean a LOT of research on woofers. After I blew up one of my Infinity woofers I knew I wanted something that could handle the power. I have a BRZ1200.1D and even though these woofers can take up to 1000 watts rms a piece, they still slap on 600 watts rms which also isn't what they're actually getting because my charging system tops off at 14.0 instead of 14.4 like the specs on the brutus says for 1200 watts. I showed my friend who got me into car stereo stuff and he said one of these woofer weighed the same as one of his 15" Kicker CVR's. They're not even broken in yet and I played a song that made my rear view mirror just aim straight down that I could never do with the Infinity's. If your considering getting these, just go ahead, you won't be disappointed!

2 type r 12d4

September 25, 2012

I have 2 of these walled off in my 99 accord (trunk wall) in a 2.98 cube box tuned to 33hz. Definitely my favorite subs ive owned. I have them running off a soundstream rub1.1600d their getting 721 watts each. Combined 1442 rms and they slam. Couldn't be more impressed. I would reccomend these IF you have the electrical to back it up and ONLY give it clean power. Great job Alpine A+ i can bump these for a full hour longest I've went and they get warm, but not hot by any means.

Sub Gone Bad

September 12, 2013

Purchased this sub about 6 months ago and installed it in a ported box and it sounded great until the cone came unglued and now I am having to have it repaired. I am hoping after the repairs are complete it will sound as good as it did the first 6 months and that it will last a lot longer this time.

There's a reason why this sub is rated 5 stars.

March 30, 2013

I bought two of these straight off of sonic electronics and received them around a week later in perfect condition. You can't complain with Sonic Electronix. THE BEST car audio website in my opinion, and i use many many many of them.

If your looking to get into car audio and you want to start out with a really nice set up. My advice would be to go with these alpine type R's. Alpine really makes sure the customer is happy.

The product:
One thing that really confuses people new to car audio may be how much power can this subwoofer really take? It rated peak is 3000 watts. NOW, although alpine does underrate there subs for the safety of you not blowing them, That doesnt mean you go and get a 4000 watt amp. 2 of my R's ran perfect on a 2000 rms amp. The subs always ran cool and never got warm for me once... and im picky about checking that stuff. This sub shines in style. REALLY good looking sub.

The bass!
This is obviously what everyone wants to see. and let me tell you, you cant go wrong with this sub. If you have the money, and are looking to get a quality system. Look no further because this is the one. For 169$ per sub I was blown away at how loud these things were. Along with them being loud the quality of the sub is beautiful. They really punch out clear bass notes. Defiantly a 5 star sub, I still have these currently hooked up in a buddies car and he loves them, never given him a problem for a year and a half.

Best Investment & Sub!

January 10, 2013

I bought a pair of these after some idiot stole my L7's. I used to have a pair like 2 years ago and they were good so i bought them again and i would have to say this is one of the best investments I've had. ive had them for about a month now and they are flawless. They're not over expensive and they POUND! I have them paired with a Rockford Fosgate T1500-1BDCP amp and they shake everything in my jeep. These hit alot harder than my L7s ever did. I put them in a Sound Ordenece box with 1.61 cubic space each. I will have videos up on youtube soon. Feel free to check them out: Rockford Fosgate t1500 with 2 type rs.

Really great sub!!

December 14, 2012

I ordered this sub because I have ears great things about it and wow does it live up to the hype. I also ordered a sealed box to go with it and am very happy with the quality of both products. I've got the sub wired at 2 ohm to an alpine mrp-m500 and I must say it sounds amazing, with both good sound quality and bass. I am however considering upgrading the amp and also getting a ported box because it is currently getting 500 watts, half of what it's rated for and i want to hear it at its best! I would definitely recommend sonic electronix to anyone looking for the best deals and super fast shipping.

Still breaking it in so the gain on my mx-50 Alpine amp is only up 1/4 of the way and this single sub shakes the mirrors in my olds alero and gives a nice back massage! Cant wait to hear it slam when i adjust the gain! Very crisp and clean sound.

Great sub, so-so in reliability

May 16, 2014

I have been an Alpine fan in general since the mid to late 80s. I have always relied upon a great head unit, amps, and even subs. This sub is no exception. However, here's my take on the matter.

The sound quality itself is really good. Toanlly accurate, tight, deep bass in my sealed box. Power handling is exceptional as well (hitting 2 units with about 700w RMS RF power). Not bad at all.

However, recently the cone has separated from the surround from daily use. I do not compete, and I don't listen at compettition levels. I listen at moderate levels only. When a sub recently blew, I thought it was the voice coil. But in this case it was not that. I think Alpine quality has been slowly dgrading over time. Still a GOOD product / good value for the money. But there are better subs out there, you just need to do your homework.

As always, you get what you pay for. I am in the process now of having the defective sub replaced. Sonic has been really good overall since my first purchase years back. I love them overall and will continue to do business with them.

beware, not true 1000rms, will overheat with extended play and fail.

October 16, 2013

These are great subs for the price, but dont beat them to true 1000 rms playing dub step or hip hop. 30v at 1 ohm with 50hz tone and this soon will blow easily! After first one failed, then the replacement failed, i own a hippo 122 and now unleash my amp at 39v 1 ohm load and am afraid of my car falling apart! If you have over 1000 rms amp just get 1 hippo 122 you will make your friends jealous when they see it's only one 12 in the trunk! Thanks sonic for the great prices and selection!

Not only do they hit hard with a small amount of power but they can take a beating. I started off with about 350 watts per sub... I am now pushing 1300 per sub and they don't skip a beat. Tight solid hard hitting/low frequencies for low bass.

Bad a** subs

November 24, 2012

Just purchased and installed two of these Alpine 12s and I must say they hit hard I am really impressed with how they sound I have them hooked up to a Rockford fosgate 2-channel 1800 watt amp subs wired at 2 ohms it makes the chairs in my EXT feel like a massage chair I can only imagine how they will sound once they are fully broken in as right now I have the bass negative 13 on my screen and amp remote turned down.

Very satisfied--recommended

August 1, 2012

Usually when I see a full 5-star rating I think it's just a fan boy who doesn't really know what he's talking about. This is an exception.

*Value* - $200 for 1000watts? That's incredible
*Design* - Dead sexy. Perfect with black interior.
*Durability* - Very strong. See below.
*Features* - Included jumper cables and connections - very convenient to wire the sub to its final ohm rating.
*Ease of use* - Manual is very descriptive and includes diagrams of all the different wiring options. Wiring the jumper cables and the speaker connections to the amp was very easy.


This woofer was a huge upgrade for me. I went from 2 DUAL 12" in the rather large, flashy bandpass enclosure of theirs to this Alpine sub in a Sound Ordnance ported box. I've got a Hifonics Brutus 1200.1 powering it at 2ohms.

While I'm still breaking it in and tweaking some settings with the tuning, I have to say I'm very happy with it. With my bass knob, I can dial it down and get very clean, subtle bass perfect for really any genre. Upon cranking it up, it hits *very* hard and I soon forgot I only had one 12" in my hatch.

It seems to keep at a low temperature, and I have my gains and bass boosts set pretty conservatively. I tuned my amp with a multimeter to reach the desired voltage. It looks amazing--huge upgrade, in my opinion, from the older type R's. Flexes well, no noise, etc. I do sometimes smell the woofer at high levels, but I think it's just being broken in (with the DUAL's I learned what voice coils smell like). Also, that magnet is *heavy* and this thing is tough.

Overall, if you want a sub that hits very hard cleanly, or one that cleans up and compliments the mix, this is perfect.

Alpine's uppin their game

May 25, 2012

My friend has one of these wired at 4 ohms he has a cheap amp so it probably gives the woofer around 200 watts, I connected the sub to my Rockford T1500-1bdcp which puts out over 1000 watts @ 4 ohms and the alpine really started slappin (no audible mechanical noise at 1000 watts either). 1 of these is good on 1000 watts, I would definitely get one if looking for good bass out of a single sub. 2 of these on an amp up to 2000 watts rms would be super loud. This is a nice sub I recommend.
Don't know anything about its durability.

I will go ahead and mention, I am definitely an Alpine guy, so I am biased. I have several of their products and I love all of them, which is why I decided to go with this subwoofer in the first place. I have never had a problem with Alpine.

I had an older Alpine Type E before I bought the Type R, and there is a big difference between the two. It is much louder and you definitely feel it more. It vibrates everything in the car. And I only have one. Two of these would be crazy.

I am running it off the Rockford Fosgate R500X1D amp, which powers it very well.

I put the Type R in the same ported box I used the Type E in, which isn't a even a good box, but I'm planning to get a proper enclosure built to the correct specs soon, so I'm sure that will make it sound even better.

I can't really speak about the durability yet, but based on my prior experience with Alpine, I have no doubts this sub is made well and will last a long time. It weights almost 30 pounds!

This sub sounds great, looks great, and you really can't go wrong with Alpine. Buy it!

No complaints.

December 2, 2013

A friend of mine recommended these to me because I was looking for tons of power without a huge hit to sound quality. So bought one, it hit so hard, and sounded so good i bought another! My Only complaint is the way you have to put the speaker wire into the sub i found it quite hard to get the wire to stay in place. Really this sub is just a great mix of power, sound quality, and price! As long as its from sonic other websites this sub was $279 bucks!

March 19, 2013

I initially got the previous model which could handle only 600rms and I cracked the spider so I wanted to get something that could handle more power. This subwoofer put in 1.8cu ported slams lows like I have two 12's in my trunk. PLUS I am only feeding it 3/4 power on my alpine mrp m500. Compared to the previous model this sub is more than worth it.

I have a single 12 dual 4 ohms pulling 2 ohms from a Alpine M110. It sounds nice but the amp is just a little to powerful for it, I have to keep all the levels down in order not to damage the speaker. I'm thinking about changing up and maybe getting two subs just to be able to get the most power out of everything.

Thourougly impressed. Clean. Loud. And DURABLE.

December 1, 2012

Sometimes people say "you get what you pay for." Well, this is definitely NOT the case. Alpine has surely been generous in this deal. I bought one of these back in march only to watch my cheap 1600 watt lanzar push the sub until it went into thermal protection (which was a 6 hour trip from Dallas to Lubbock) the sub though: a little warm. Alpine must have solved the heat problem for sure.
I guess the next thing to note is durability. Being a teenager in high school I always have people in my truck and with a console box, people touch the speaker while its running and stuff gets put against it. Worst it got: a scratch
I recently upgraded in September by buying a second one and building a new custom box. So end result: 2 swr12-d4's in a 6.67 cube box (yes I know it's oversized) running abt 900Wrms. Got a friend with a meter: pushing 116.
Recently bought a Hifonics glx2200.1d and HOLY MOTHER OF GOD. My friend's meter cuts out at 130 so now I have to go find a term lab to test it. Now with the right power this audiophile-to-be can't be any happier because I can now have the sound quality to match a system many times more expensive but also possess the power to show off upon occasion.

ALPINES NEW TYPE X+

December 2, 2012

Alright maybe im over my type X but this thing is like, man I can't even explain it properly you gotta witness this before you even talk about this sub. There are some people writing neg reviews cause they don't know how wire and give power to this baby properly. My experience of this sub. It actually hits harder than my type X and weights less and takes less space inside my enclosure. It's sexy and sleek, had some dudes trying take pictures of this like it won a competition or something. You can't go wrong with alpine I got a alpine CDA-105, got a sub now and speaker system on the way. Easy install, beast connections. In and out like a 1st night stand but this baby you just wanna KEEP ON HITTIN! This the baby u wanna introduce your family to cause she is a keeper.

Alpine made a fake advertisment for consumers but!!!!!!!!!!!!!

November 17, 2012

I would highly recommend the alpine type r they hit very hard and clean unless you don't have the electrical, a powerful amp , the right box , the right gauge and battery and everything , then they wont hit. alpine really did change the type r completely i mean the previous hit harder but the power wasn't still balanced because it has 1800 peak and 600rms that's not a balance sub-woofer if you look it the rest of the company's they have there rms half of what the peak is for example if the sub-woofer is 1000peak then the sub will be 500rms, alpine usually doesn't do that that's why they always have problems but finally the first time they have the rms of the new alpine type r balance with the peak thats how you'll get a good system in your car especially when it comes down with the rms power, but iam still breaking in the subs, and i kind of smell something weird when the sub-woofer hit maybe iam breaking into them ill wait more time and see what happens just recently still bought them, the alpine type r does not do 3000 watt peak that's for sure because i heard a 3000 watt sub-woofer and it pounds super hard compare to the new type r and that's a fact and proven that type r doesn't do 3000 watt peak its 2000 peak 1000rms look on alpine.com and see for yourself and if you have the these subs you could tell they hit 2000 peak and for sure 1000 true rms they lied about the peak power but not the rms i have 2 of these in a sealed box with an alpine pdx m12 which mine is rated 1450 rms at birth sheet at 12 volts which is plenty enough for the type r each getting about 700rms each that's good you don't want to go over you could but i like to be in the safe side and not put pressure on the voice coils even thou they build the new ones strong. and my system pounds super clean and sound quality is amazing for the money you pay for. my chest pounds and my teeth rattles but for a fact not 3000peak or else I'll be ****in up car alarms in the parking lot like crazy because a peak means how much can the sub pinch it doesn't pinch 3000 it pinch 2000peak for fact and alpine even said it , so they made a big false statement to the consumers and thinking there going to get the same power as the 13w7 jl audio because it has about 1000rms and 3000peak. lets be straight here the previous version has 1800 peak and now the new ones have 3000 peak now lol that's funny the news still pinch about the same as the older ones just 200 peak difference not 3000 watts my ass.
but overall the the previous type r hit good and hard but not enough rms power as the alpine type r d4 which does 1000rms clean and true, and the new ones to let you know i still bought them but since it hit truly hard and clean and sound quality is outstanding , i have to wait more time and I'll see what alpine really did to the new type r and will see what there up to if its worth, but other than that i would recommend to anyone buying these sub

what would be the best amp for a set of swr-12d4 subs?
scott on Sep 1, 2014
Best Answer: I'm not 100% sure, but I have a 1000/1 jl mono block and it plays pretty good. No issues or blown subs yet. I'd stick with any amp that is 1000 watts or more just to be safe and have a little extra power incase you upgrade later. Don't get a amp with not enough power and cause distortion because of the amp not strong. I have those same exact subs and I know they say they can play 1k watts but I think for these speakers, it can't handle that power, I believe they're 600 watts rms, so a amp that has maybe 1200 watts or plus will treat you good. Hope this helps

hi there i have 2 alpine mrp m500 can use it on this one sub single 12 sealed subwoofer box ? thanks bud
A shopper on Aug 17, 2014
Best Answer: Yes, however the sub pry will not require that much power. I run to 10d4s in my truck in a sealed box at 1200 watts between the two of them and its more than enough power. I also run the same set up with 2 12D4s in my ford edge in a labrynth ported box with the prime series 1200 watt fosgate and it hits hard as hell. I would try just the single 500 m class fist yhendecide from thrre

hi there i have 2 apine mrp m500 can use it on this sub? thanks bud
A shopper on Aug 17, 2014
Best Answer: Hello,

We highly suggest only using ONE MRP-M500 on ONE SWR-12D4. You will be getting the 2 ohm rating of 500W x 1 , which everyone knows is an underrated figure. Assuming that, you will be Very happy with the performance.

I purchased 2 Alpine SWR12D4 subs from you and I am wondering how do I wire them so I can run them at 1ohm since I have a 1800W mono amp that is 1ohm stable?
Scooby on Apr 24, 2015
Best Answer: It will not allow me to link you to any particular site... Do a Google images search for "4 ohm to 1 ohm diagram" and you should find images to help you on your way. I have these speakers also and I had them hooked up to a Zeus ZRX1800:1 Amp and these babies pump and are clear on the bass so its not just boom you hear but actual varying levels of beats and bass... Everyone tells me that its the clearest bass theyve ever heard. I turn heads wherever I go! B-) Trust me... You will not be disappointed!!! One helpful hint: Use a Stinger amp hookup that will handle the wattage(has to be thick wire) for it and you wont have to worry too much about power drain. See the one im using...

can I drop this down to 2 ohms?
7UK Face on Apr 21, 2015
Best Answer: Yes connecting them in parallel will give you 2ohms. Meaning since its two voice coils, you connect negative to negative and positive to positive then run the wires to the amp

Best Answer: Hello,

We highly recommend getting into an amp that matches the QUALITY of the Type-R drivers. Power Acoustik is an entry level manufacture, so the performance will reflect that. To your question, unfortunately the amplifier is not CEA compliant so the figures are a bit too skewed to provide an honest answer. However, crunching the figures suggests that the amp can do ~1600w True RMS, which actually makes it a fairly good match for the SWR drivers, Numbers wise. Still, the quality just isn't on par to Alpine Type-R products.

This may be a stupid question but when it says "dual 4 ohm subwoofer "... does that mean that when you order this, there are two separate Alpine subwoofers? Thanks
skerdock on Sep 2, 2014
Best Answer: Hello Spencer,

The sku you have written your question on - for $319.90 - IS for Two SWR-12D4 subwoofers.

Below is the link to the Individual subs.

i am just about to buy 2 swr-12d4 alpine and 2 Planet Audio AC3000.1, i am wondering if one of the amplifiers is as master and 1 as slave can I used them at 1omh with the subwoofers? thanks!!
benjamin on Aug 1, 2014
Best Answer: Hello Benjamin,

The BRX2400 is a traditional MONOBLOCK, that just happens to have an extra output for situations Just like this. You will simply wire EACH SWR-12D4 in Parallel, to a 2ohm final Load, then give EACH one its own channel. The amp will then bring the connections together INTERNALLY, and bring the impedance down to 1ohm.
If this is too confusing, then simply use ONE Positive and ONE Negative, and treat it as a traditional amp. Neither way is better than the other!!
Also, we highly recommend NOT going with the 2400 RMS model. That is waay to much power for these subs. 1000w RMS to each - despite what the manufacture's claims are - is also pushing the extreme but more tolerable.

Best Answer: Hello,

This is highly discouraged. There is no product that Boss makes to match the performance of the high end Alpine Type-R series. The Amplifier will run the drivers, but never to the potential that justifies the price and hype of the SWR-12D4.
Assuming the amplifier is really doing the figures it suggests (questionable because it is not CEA Compliant, and the price seems a bit suspicious) then you will require 0 gauge OFC wiring.

So, I just put two of these in the trunk of my 2005 Saturn Ion in a sealed box powered by a Pioneer GM-D9601 and I am wondering what the best gain and frequency settings would be? I would like them to hit hard at high volumes but I also want it to be crisp and clean and be able to hit the quick bass when its there. If it makes a difference, my head unit is the Power Acoustik PTID-8920B. Thank you in advance!

Best Answer: Hello CJ,

The Power Acoustik PTID-8920B doesn't provide the greatest signal, so your Gain will need to be turned up fairly high. The higher the gain is set, the lower the overall sound quality you are able to reach. This isn't a Terrible thing, 2v is a common figure, but we want you to understand that there is always room for improvement on the final outcome. We suggest setting your LPF, or "Freq", to ~80Hz. This will be roughly the half way point between 60-125Hz .

Setting the gain, however, isn't as easy as just giving you a figure. Please do a bit of homework of your own to understand the setting. Below are two link to give you a headstart.

im getting a 10 and a 12 in these speakers. What size and type of amp would be best to push them?
A shopper on Feb 10, 2015
Best Answer: Hello,

Each driver is asking for the same power . So we suggest two Monoblocks providing ~750w RMS @ 2ohms . Two NVX JAD1200.1 , one for each subwoofer, will work very well.

what hits harder 2 Fosgate P3D4-12 or Alpine SWR-12D4 ?
A shopper on Sep 13, 2014
Best Answer: Hello,

Before giving you an answer, we Really hope you understand how general/vague/subjective your question is.

Assuming all things equal - power/environments/components/settings/etc... - the Alpine SWR-12D4 will have a slight edge. This has Nothing to do with power ratings - which the Alpine SWR-12D4 CANNOT hold 1k continuously - instead it is based specific specs. Of which, suggests the Alpine SWR-12D4's excursion will be further, and will reach lower frequencies.
