Our take on the Alpine SWR-10D2

Alpine's Type-R subwoofers will bring big bass to just about any vehicle. The SWR-10D2 10" 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.

Bring on the power

The SWR-10D2 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.

These subs sound fantastic! Super clean. I have not broken them in quite yet but so far they are awesome! Only complaint whatsoever that I have is that the jumper cables to bridge the subs to not fit nice and snug they tend to be loose and come out quite easily.

Evey bass note is hit very perfect. You do have to break in the subwoofer though but after you do, it sounds way better. I bought the ground shaler box and it helps out a lot as well. The amp i have on it is the alpine MRV-F500. I just have one and man it bumps so loud in my truck

Pros: Loud bass, easy to install, instructions come in the box


bass for your face

Rob from seaside california on 12/28/2014

I have 2 of these subs in my ranger ext cab. At first I had small boxes but didn't get the bass I was looking for. Bought the recommended box and WOW....i literally need ear plugs now either wise my ears are ringing. My girlfriend hates it unfortunatly.I have the alpine m110 amp which puts out 1100 rms. Tuned at 25hz

Pros: Good bang for your buck

Cons: None yet, just bought them so longevity is still to be seen.

Great sub

Charlie from Gulf Shores, Alabama on 7/25/2013

This is a great cost effective sub I have two in my car and I plan on buying two more soon for my truck

Pros: Massive sound

Cons: None

Jleff8621 from Virginia on 7/5/2013

Great product overall. I had mine in a poor box however and the surround came off of the cone.. But i got it fixed and got a new box and now it just completely blows me away. This thing is a monster!

Pros: Nice deep bass, Loud, And just about everything else.

Cons: Pretty much nothing.

Great Sub

ryan from aliquippa pa on 5/1/2013

When first hooked the Alpine up it just amazed me how bass this 10 could produce, unfortunately I unknowingly paired the wrong ohm loads with the amp and ruined it about a month later, but I can easily say go for it if you want really deep bass that hits every note.

Pros: everything

Cons: non

Alpine type r 10d2

Dat-OD from atlanta,GA on 7/21/2012

This is the best 10" sub ever. I had a 10" MA Audio with a giant magnet, the same size as the sub itself and I thought it was loud. After replacing it with the alpine and kept everything on the same setting, this alpine felt like it was twice as loud. It's shaking my whole car. Very clean bass. Very amazing for a 10 inch. I'm pushing it with a 1000rms class D TMA amp made by JL audio in an Obcon GZ hidden chamber box. Worth the money. Words can't explain!!!

Pros: best 10' for the money.

Cons: None

Jason from Waynesboro, Va on 6/3/2012

I bought this sub to be paired with a Profile AP 2000. Bridged @ 4 ohms the amp puts out 960RMS. The sub was replacing 2 infinity kappa 12" subs. I have a growning family and needed to reclaim some trunk space in my G6. Purchased this sub on 5/29 and enjoyed it a lot but just didn't quite have the deep punch that I had with 2 12" subs. Gave it a few days to see if it could grow on me & after comparing box sizes etc and realizing that the space & cost would be minimal to upgrade I decided to go to the SWR-12D2. I switched it out on 6/3. I spend a good part of the day putting the new sub through its paces and was unable to find any type of music that the 12D2 didn't preform at.. For the extra $50 between the box & sub it is well worth it to invest in the 12D2.

Pros: Ample power handling and responsive.

Cons: Leaves a little to be desired for the broad spectrum of music that many listen too.

JOHN from Richmond, VA on 5/15/2012

I bought two of these a few weeks ago and didn't realize that they've been improves since the prior versions of this subwoofer. If you are unaware, this subwoofer is essentially the Type X of the previous generation, which is fine by me, this subwoofer is amazing to put it simply. Have yet to have any issues with it so far. I have 2200w RMS going to these subs and they take it all day. they don't even get warm. I would highly recommend this sub to someone who wants some great bass, and doesn't want to spend tons of money on a subwoofer.

Pros: Great price, power handling, size

Cons: None that I can think of. lol

Enclosure Compatibility


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).

Enclosure Compatibility

Sealed Box Volume: The recommended sealed box volume ranges from 0.48 cubic feet to 0.93 cubic feet, with 0.58 cubic feet being the ideal size.

Ported Box Volume: The recommended ported box volume ranges from 0.83 cubic feet to 1.38 cubic feet. The ideal size is 1.1 cubic feet, using a slot port measuring 10" (W) x 1" (H) x 20" (L).

That's how I run mine and they sound great and I am always getting compliments [ Carter  Jan 15, 2018 ]
Yes, just need enough space to allow for the excursion of the sub. [ Robert  Jan 15, 2018 ]
it depends on how much room you have [ Augustine  Jan 14, 2018 ]
Absolutely. Just take into account speaker excursion. You don't want it to hit the floor. [ michael  Jan 14, 2018 ]

Dear Tyler M. I installed two of these incredible subs in an enclosed box downfiring 1 inch above the floor power by the Alpine mono amp PDR- M65. And I stay awake at night unsettled by the fact I have to leave my truck out there with the system off. Seriously, that was a shamelss plug which translated means I am so happy with the dual coil subs that I can't contain my excitement. I remember jumping the the two separate terminals in each unit, look into parallel ve series connections and make sure you are doing it one way or the other and find a speaker you know works and try it. The head units are complicated these days, you may not be sending the signal you think you are so do yourself a favor before you waste hours and hours, test with something else, even a multimeter or somthing like that. Hope that tells you you made a great decision even if you need to exchange it, call the boys at install at Crutchfield, they will help you through it or send you a replacement, That Crutchfield has the best customer service of any company I have ever in my 50 years had the pleasure of working with. Good luck. [ Michael  Apr 16, 2015 ]
Only thing I can think of is signal wire [ ROBERT  Apr 15, 2015 ]
Do you have the sub wired to power at 2 ohms? The alpine 10d2 is a 2 ohm sub. There is also the 4 ohm version which is 10d4 you might have the sub wired to power at 4 ohms instead of 2 ohms which is what you need to wire it at. [ Tyler Joseph  Apr 15, 2015 ]
Your remote sensing might not be hooked up or even working. Try sending power to the remote sensing terminal. [ Rogelio  Apr 15, 2015 ]

You need to power them,I ran a alpine 500 rms to each Voice coil( 4 amps total). I went with d2 so I can power them with 500 rms at a decent price .4ohm may be more stable ,but I am not sure.i don't regret getting them they hit much harder than my s series,I would go for it!! [ ROBERT  Jun 25, 2014 ]
If you buy two of these alpine sub's, you will need to purchase an amplifier as well. Once you decide if you wanna go with the D4 or the D2's them decide on the amp. If you go with a D4 then you will wanna buy and amplifier that will match the 4 ohms of the sub woofer. Preferably a class D mono amplifier. This goes the same with if you go with the D2 alpine. D2 is @ 2 ohms so same here, I would recommend a class D mono amplifier as well. Now deciding between a D2 or D4 is on ohms. D4 requires more power to make the subwoofer preform while a D2 requires power but not as much. I went with the D2 10" alpine type r. If you were to go with two of those ones I would prefer getting and amp that is at least 1200 watt RMS. But overall first decide which subs you want either the D2's or D4's. After deciding on that make a decision on a class D mono amplifier that is rated and matches the ohms selection specifically from the sub (2 or 4 ohms). I definitely would stay with an alpine class d mono amplifier just to stay with the same brand so you won't have worries of something not matching up. I know for a fact you won't be disappointed purchasing an alpine type r subwoofer. These are well put together and can take a beating. I hope this helps good luck. [ Tyler Joseph  Jun 24, 2014 ]
You'll need an amplifier and an amp install kit. I recommend the Alpine MRX-M110 amp. If you have this amp go with the D2's. That makes it two Ohm capable. If you go with another amp you'll have to check the specs to see if it supports 2 ohm or 4 ohm. Hope this helps. Good choice of speaker by the way. [ BRANDON  Jun 23, 2014 ]
