Rockford Fosgate R2SD4-12

At first i was very unhappy with these woofers. But after a week or two of using them they seemed to get louder and better. Still not what i was hoping for but i can't complain with my crappy amp. I have a crew cab with two of these behind the seat. They do a good job of putting out the bass threw out the cab.

Very nice shallow subwoofer

I bought this for an install I did for a friend. I wish we could have used a larger box. This is a great sub that would be even better in large box.

Subs review

i would recommend these to anyone. they sound great. Haven't had a single problem with them. 2002 chevy silverado 1500hd crew cab. they're under the seats.

Nothin like a Fosgate

I am i huge fan of this brand and the R2sd4-12 was just another example of why it is such an amazing brand. This is an excellent subwoofer, it's cheap, and it fits in small spaces. Can't ask for much more.

Update

I did order another one and wired the dual 4 ohm voice coils in parallel and surprisingly I put a multi-meter up to it and measured for ohms and got a reading of 3.6 ohms on both subs. Not bad, not bad at all.

thumping

I have 2 of these installed in a sealed unit on the mid gate of a 2002 avalanche. I have a planet audio ac1800.5 amp pushing them and they sound sweet. I like the tight clean sound but the will boom with the best.

Very good shallow mounts

Mounted 2 of these in a sealed box under the rear seat in a supercrew truck running 1000 watts @ 1 ohm. The box spec was just over .5 cu ft each and even with poly fill the air space is a bit under but I heard these could probably handle it and they did. I've worked at a pro installer years ago and I would not have expected the bass quality these produce in such a shallow mount and tight box. I'm pretty impressed and at this price I'd say they're tough to beat in terms of value.

awesome!

If You're Looking For Huge Bass, These Are Not The Subs You Want. But If You're Looking For Great Sound Quality With GoOd Thump In A Small AreA, These Are What You Want! Tight And Responsive, Clean SOund, And A Great Product. Would Buy Again!

Great Sound!

The speaker sounds incredible. I built a speaker box to replace the stock floor in the hatch area of my Mazda3 because I didn't want to use up all of my valuable storage space with a speaker box. Since my dimensions only allowed me a 3" mounting depth and approx. a 1cu. ft enclosure volume, I had to start shopping around for a shallow mount speaker that would work with such a small enclosure.

I have the speaker powered by an old Kicker ZR360 in bridged mode @ 4 ohms. With this set up, I'm putting about 360 watts RMS into the speaker. Let me tell you, the speaker downright bumps.

I wouldn't hesitate to recommend this speaker to anyone looking for a shallow mount and/or low volume speaker setup.

Great value!

It's hard to find a better value than this shallow sub. It doesn't hit as hard as my 12" L7 on the same Punch 300 amp but that's kind of comparing broccoli to asparagus.. Buy this sub! Awesome value.

sounds great

I had them bridged to 2 ohms to some old 800watt amp i bought for 20 bucks. they slap! knocked super hard and sounded great. i have 2 in a truck box for my ext cab silverado. the amp kept going into protect mode...come to find out it was the wrong amp...so now i have them wired to 4 ohm set up and they just sound like good speakers. I ordered a 1400 watt amp so we will see how they like that!

Amazing subs .

At first like everyone else i doubted that these would hit hard brcause they were shallow. I was so wrong they hit hard . I can be heard coming down the street . And it doesnt take much space . I have them in my dodge ram quad cab and these are so worth it . Such a great product.

Gonna order me another one

I have a 1974 GMC single cab truck, I dont have very much room to work with and these are just perfect for the job. At the moment I have just one being powered by a 250 wattbridgeable Wal-Mart brand amp and have placed the driver in the middle of the bench seat, I can feel the bump but only on one side of my body, must order another one for both me and the passenger. Will also order an amp to match. :D



I just like the bump. :D

Rockford ROCKS!

Bought this to add some umph to my F150 Super Crew stereo. I have a bridged Rockford Punch P3001 and a single sealed enclosure under the rear passenger seat .9 cubic ft. The single 12 produces very tight punchy kick drum and produces low end instruments extremely well. For my situation and considering the room restraints for the box, I can't imagine anything sounding better. I have to keep the Sub output on my Clarion head unit turned waaaay down to keep it from completely drowning out the rest of the system.... if it suits you space and requirements, buy it, you wont be disappointed.

Great value

very good subwoofer, to me was great sound and good price

Rockford Fosgate Prime R2SD4-12

I am very pleased with the sound quality of this speaker I have one 12 and a mix match set of 10'S MEMPHIS POWER REFERENCE AND A AMPLE 400W ALL ARE IN THEIR OWN BOXES 1000 WATT PIONEER AND 250 PIONEER IN A ASTRO VAN BEAT SO HARD KNOCKED OUT THE SIDE GLASS ....

Great speaker

I would recommend this speaker for a single cab, I put it in my 85 f-150 and it sounds great I haven't had any problems with sounds quality and it definitely has a thump.
