Our take on the Rockford Fosgate R2S-1X12

Big bass in a tight space
Rockford Fosgate's Prime Series R2S-1X12 shallow sub enclosure lets you have big bass in your vehicle without taking up too much space. Coming in at 5-1/4" deep, this box was made with the regular cab truck owner in mind. Rockford Fosgate built each enclosure with 5/8" thick medium-density fiberboard protected by rugged black carpeting so they're tough too.

Perfect fit for my 94 Chevy Silverado standard cab. Hits great.



Great for a 2013 F150 super crew

Crutchfield Customer Review (What's this?)

Loving this sub so far! It fit nicely under the rear seat of my 2013 F150 super crew. Powering it with 300 watts from a Pioneer amp, it will shake the entire truck. And it's nice, tight bass. Well worth the price!

Pros: Fantastic sound from a compact unit.

Cons: None yet.

Clean Bass

Matt from Chesapeake, VA on 9/30/2018

Crutchfield Customer Review (What's this?)

Great, clean bass. Doesn't thump like a ported enclosure and takes a little more power but doesn't distort as easily. For fitting in a tight space, with a shallow driver, it does great. I removed the jack/spare tire tool caddy and cut away part of the rear liner behind the rear seat of my 2004 F-250 crew cab. Fits perfectly and sounds great.

Pros: Small footprint, fits tight spaces. Clean, tight bass High volumes without distortion

Cons: Needs more power than a ported enclosure No heavy thump vs. a ported enclosure

Crutchfield Customer Review (What's this?)

Installed Friday speaker blew Saturday. Horrible product. My son worked very hard to save up his money to put a system in his truck. Spent almost 1000.00 for all of the stuff and now has to go buy a new sub on Sunday.



Crutchfield response on 10/31/2017 One of our Tech Support specialists, Penny, contacted this customer to set up a replacement, and to confirm that the gain and settings are properly set. Lifetime tech support comes with every Crutchfield purchase, and can be returned or exchanged within 60 days.

I love it!

Crutchfield Customer Review (What's this?)

I love it! I just installed this Sub along with a Jensen DUBa1450 amp last week, and I love the clean Bass it puts out. I am new to car audio so I wasn't sure what to expect... but I am very impressed. It fit perfectly under the rear seat of my 2012 F150 FX4 supercrew cab. It put out a nice, clean thump throughout the whole cab. I highly recommend this for someone who is on a budget. I believe I got an amazing deal for this Sub! Crutchfield always amazes me with the deals they have, and their technical support and customer service is the BEST! Thank you Crutchfield!

Pros: Nice, Clean Bass. Fit perfectly under rear seat of my 2012 F150 Supercrew Cab. EASY install! Bass control remote. Looks awesome.

Cons: None so far!

Crutchfield Customer Review (What's this?)

Purchased this for my son for Christmas 2015, its now 1/20/17, going on the third one, now its bad. Crutchfield has warrantied all of them so far. I will never buy another one, complete garbage.

Pros: non

Cons: Piece of junk

Bass kicks a punch!

Miranda from Bethel, AK on 11/1/2016

Crutchfield Customer Review (What's this?)

Quick and easy install! The only negative component would be that it did not quite fit in my truck, despite that it states to be made for trucks. However, it still sounds great and I am infinitely pleased with this purchase!

Pros: Great bass Sleek look Easy installation

Cons: Too tall to fit perfectly in truck

Awesome Sound on a budget

Scott from Elkview,WV on 10/4/2016

Crutchfield Customer Review (What's this?)

This sub is perfect for behind the seat of an older model trunk and the bass in punchy and full I highly recommend this item

Pros: I can't say enough about this sub and the value that you get for your dollar

Cons: Nothing negative to be said other than I need a few more!!!!

great for price and fit area needed

GMan1039 from Houston, TX on 7/27/2016

Crutchfield Customer Review (What's this?)

This skinny sub and enclosure fit neatly behind the back seats in my GM Crew Cab truck. Not super powerful but definitely worth the price if you are looking for some bass without taking up too much room. Note, two may fit, if you are looking for more thump.

Pros: size, price, fitment, trim.

Cons: Not the deepest thump from a 12 in sub but that's to be expected for a shallow speaker.

TLH from Vermont on 2/16/2015

Crutchfield Customer Review (What's this?)

I just received my Rockford R2S 1x12 in the mail today. I don't have my Rockford 250.1 hooked up yet, but this sub is running off from a pioneer GM-A6604 amp (90 Watts rms) and this sub hits pretty well for having roughly 1/3 of the recommended power. I almost went with 2 10's (and am still curious the sound difference) but this is a simple one sub setup. This is Installed in my 2014 Toyota Tundra Crewmax, it fits perfectly behind the rear seat. I highly recommend this to anyone who has swapped out their factory amp and looking for some decent thump (will not win any spl comps).

Pros: Excellent quality, sounds great with 1/3" rms wattage, It looks pretty awesome, and it fits where other enclosures have no chance.

Cons: I cannot see it behind the seat! I wish I had room for 2 (I need room back there for my 2 amps) otherwise there are no cons.


Zack from Merced California on 1/25/2014

Crutchfield Customer Review (What's this?)

Very reasonable priced already enclosed subwoofer. No, it's not the hardest hitting bass available, but it definitely puts a nice clean sound throughout my single cab f150

Pros: Thin profile box, already enclosed, very clean sound especially when the volume is higher than normal listening level.

Cons: Could hit harder if I had to choose a con.


CraigM from Hartford, Michigan on 7/13/2013

2004 Ford F-250 Super Duty
Crutchfield Customer Review (What's this?)

Pretty good unit for the price. Sounds good using a Kenwood 600 watt amp. I don't like it quite as well as the Kenwood that I replaced due to size limitations in a new vehicle, but it will do. Sound is very "tight" and I like that but maybe a little too tight.



Works for me

N from Denver, CO on 5/11/2013

It took a bit of cutting and hacking to remove the jack mounts from behind the seats (I used a hacksaw to cut it to roughly 1/6 inch then a grinder to grind it down to be level with the truck, I used a crowbar to pull out the riveted mounts), along with pulling out the back carpet (just pull out both plastic pegs and bend it in the middle to get it out), but once I did this box fit in my '96 Single-cab Ranger. It's quite a tight fit, but it sounds good. It did lower the available space in the cab a bit, but not significantly. I'm quite happy with the audio quality of the subwoofer, and the fact that it's a 12" that fits in a tiny truck cab. Just to note, there is literally no space between the seat and the sub box. The sub box holds the seats in roughly a straight up position and the seats have to be pushed to latch upright. In hindsight I wish I would've gone with the 10" for my truck, but this one did fit and it does sound awesome.

Pros: Fits in my truck

Cons: Still a little big, wish I would've gone with a 10".

Product Research


Enclosure: The Rockford Fosgate Prime R2S-1X12 houses a single R2SD4 12" subwoofer. The sealed enclosure is constructed of 5/8" Medium Density Fiberboard (MDF) and covered with black high density carpet. There is a pair of high current spring posts on the right side (when facing the subwoofer); the terminal will accommodate pin connectors, single or dual banana plugs, or bare wire up to 10 gauge. The subwoofer's dual voice coils are wired in parallel and present a 2-ohm load to your amplifier.

Voice Coil Former: The R2SD4-12's voice coil former is made of anodized aluminum to provide superior heat dissipation. Unlike traditional plastic, aluminum acts as a heat-sink to quickly dissipate thermal build-up on the voice coil. This keeps the subwoofer cool and improves durability.

Stitched Tinsel Leads: The multipoint, periodic stitched technique of attaching the tinsel lead wires to the spider spreads stress and strain over a greater area, reducing fatigue and the possibility of shorting. This significantly improves the reliability and performance of the subwoofer.

Stamped Steel Basket: The R2SD4-12 subwoofer features a stamped steel basket for added rigidity.

CEA-2031 Compliant: The power handling specifications for the R2SD4-12 subwoofer conform to CEA-2031 industry standards. This means the subwoofer has the capacity to handle power under continuous demand, not instantaneous power handling, that over time, can damage voice coils.

Not sure, I have mine behind the seat of my standard cab Silverado. It might be too wide tho, the 10" box is much more narrow maybe a better choice for you. [ KYLE  Jul 22, 2018 ]
We do not have the available space dimension under the seat in your Silverado. You can use the dimension we provide for the enclosure to cross-reference against the space you find in your desired mounting location: 27-1/4"W x 13-1/2"H x 5-1/4"D1 x 3-3/8"D2 (This is upright; not laid flat) For additional assistance and personalized recommendations, feel free to contact us directly by phone or through our online chat service: [ Ryan  Jul 19, 2018 ]  Staff
It should fit, it fits behind the back seat of my 2006 2500 GMC with plenty of room. Its a pretty slim box made specifically to go behind a truck seat. [ G  Jul 27, 2017 ]
Yes it should as I have this in my 2008 Explorer Sport Trac. Double check the dimension specs of the box on the website. [ Stephen  Jul 26, 2017 ]
I think it would be a tight fit behind the seat. Mine is under the seat in my 2011 F150 super crew. [ Andrew  Jul 26, 2017 ]
I cannot find a actual spec, but the owners manual is at Rockford's website [ RAYMOND  Feb 03, 2017 ]

Depends on how much room you have behind the seat really without knowing if you have an extened cab or crew cab or a regular cab truck I can't answer your question [ Steven  Feb 15, 2016 ]
This will easily fit. It fits behind my 2000 GMC single cab. Sounds great! [ Shaye  Jan 29, 2016 ]

It fits in my 93 f150 with a bench seat single cab just fine. Sounds great [ Scott  Jan 05, 2016 ]
I think they would fit depth wise, but it might be really tight to fit two width wise, I put one in a 2005 f250 and it looks like two would be kind of tight. [ Casey  Jun 24, 2015 ]
No sir [ Robert Blake  Jun 18, 2015 ]
Probably not two but would fit great! [ BRANDAN  Jun 18, 2015 ]
