Awesome!! This is the second I've owned. First I sold to a friend of mine. For the size of this thing it puts out some big power. Budget friendly and can push power forever without getting hot.

Pros: Small and compact. Great power and 1ohm stable. Easy to adjust setting! Remote bass knob is a plus! Comes with mounting hardware for amp as well as remote knob.

Cons: I tried to think for a while about an issue with this amp. Yea sorry can't think of one.

Great product. This amp came as part of the RF 1200W bass package. This is a very powerful amp. I am running it at 1 Ohm load. I am still breaking in the subs so the gain is still set well below halfway. It pounds so hard, I can't keep it turned up. This is one of the best amp purchases I have made.

Pros: Very powerful. Great price.

Cons: None yet.

Crutchfield customer from Miami, FL on 11/30/2018

Verified employee purchase (What's this?)

Great amp for 2 Ohm load. Unstable at 1 Ohm. Hooked it up to a 2ohm 12" solobaric wired to 1 Ohm and ended up having to change the sub to a 4ohm wired to 2ohms since the amp wouldn't stop going into protective mode . Input gains were set as recommended by Crutchfield and speaker output set to a max of 35V to try solving the issue but I was never happy with the performance. To avoid issues and be pleased with this amp plan on a 2ohm total load.

Can't believe this is so small. My first mono Amp, this is powering a Image Dynamics IDMAX 12", which I picked out with the help of a Facebook group when asking what kind of a subwoofer I should get. The IDMAX is very comparable to the W7 according to some more experienced people than myself, but more of a SQ Dominant sub, ranther than the W7 which is more SPL. I was pretty close to getting the W6. Amp makes this thing pound and I love it. Exactly what I was looking for! Amp was rated 1252 RMS @ 1 ohm.

The best amplifier I've had to-date!

Jacob from FL on 1/4/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

It came with a birth sheet that says my amp can produce 1,295 Watts RMS. You know you have a good amplifier if it makes more power than advertised! This is most likely a lot more powerful than the Hifonics HFi1500D I used to power two RF T0D412's 4 years ago. I have no headlight dimming with this amp, either! I'm only running a 110-amp stock alternator in my Maxima. I'm also using a Kicker CK4 wiring kit with 12-gauge Kicker speaker wire from amp to sub. I'm using this amp to power one Rockford Fosgate T1D412 in a 1.65 cu.ft. sealed enclosure. Running on 2-ohms at 85% efficiency (800 x .85), this system sounds a lot louder than 680 watts RMS! But since the birth sheet showed 1-ohm RMS at 1295 watts RMS (8% higher than advertised), I'm willing to bet that my amp makes somewhere around 864 watts RMS at 2-ohms, which at 85% efficiency would be 734 watts RMS. I definitely will be buying RF amplifiers for every system I build in the future. I will definitely consider purchasing a Power series amp if I ever decide to get a high-output alternator to handle the power!

Pros: Compact, efficient, runs cool, can run two subwoofers, more power than advertised.

Cons: Doesn't have a clip indicator.

Got this amp about 2 yrs ago. I paired it with the 10" L7 Kicker Solobaric. Crazy sound that i enjoy. The amp has given me no problems. Provides nice power for a power hungry sub. I sold the L7 and ordered a Rockford Fosgate P3 in the box that should be delivered in a few days.

Pros: Foot print. Power. Reliability.

Cons: None, for my application.

Rockford Fosgate has lived up to expectations again. Great amp that is well worth the cost. I'm pushing 4 10" subwoofers with this amp and 4 10" subwoofers with another brand (DB Drive - Speed series). To match all my subs the other brand is turned as high as it can go without clipping and the Rockford Fosgate is only at about half power - proving again that Rockford is a much better amp over their competitors.

Pros: Very strong and easy to set up

Cons: None

Rockford Solid Amplifier

Albert from Conway, AR on 4/8/2017

Verified customer (What's this?)
Verified employee purchase (What's this?)

The Rockford Fosgate R1200-1D is an excellent amplifier. Using it to power 2 Rockford Fosgate P2D2-12 subs (800 watts RMS with a 2 ohm load configuration) and receiving the signal from an AudioControl LC2iB line output converter. The amplifier has a gain that goes up to 11; I have it set to about 4.5. With the line output converter set correctly and the volume at the stereo set to about 80% of maximum, the subs can be felt a block away without any distortion. The amp runs cool and only warms up when I have it turned up to generate thunder-like bass. With the low-pass filter and the subsonic filter set correctly I am able to get excellent bass sound that is clean and distortion free. Power and speaker cable connections are secure and will definitely not come loose. Be sure to use good cables, I went with the Rockford Fosgate RFK4X cable kit. I would definitely not go any smaller than the Rockford Fosgate R1200-1D. In my humble opinion, you are better off saving your money to get a bigger amp like this one - you will have plenty of extra power and you will not be disappointed. Rock on!

Pros: Plenty of extra power, no distortion, runs cool.

Cons: The Punch Level Control module blue LED light is very bright, I had to partially cover it with electrical tape.

Top of the line amp

Armando from Denver, CO on 2/9/2017

Verified customer (What's this?)
Verified employee purchase (What's this?)

I got the RF R1200-1D as part of the awesome Crutchfield RF bass package and boy am I pleased! This thing is a beast. I also have the RF 4 channel 600 watt amp and I think this is the perfect combo. I have this wired at 1 ohm to two RF 12" P2's with a Sound ordnance bass bunker sealed box and it pounds. It seems like at the stop light, by the looks of people two cars ahead I can be heard at least that length. That withstanding, the prime line is supposed to be an "entry level" series of RF products however, I don't think that any "entry level" term can be applied to Rockford Fosgate. I'm a travelling nurse so I drive a lot, sometimes I'm out driving intermittently for 8 hours and this thing has yet to show any signs of heat or failure. I expected RF to deliver but man did they surpass my expectations, once again. This amp is definitely the best value out there.

Pros: Top of the line quality for value price, Rockford Fosgate

Cons:

She's a Beast that seems to have power for days. It pushes my twin Kicker Comp RT's hard. Super easy to tune to your preferred bass response. I am very pleased so far. I have it mounted between the subs behind the rear seat of my Tacoma double cab and it runs very cool. I've taken a 1.5 hour trip running it pretty hard the whole time and was really surprised when I got out how cool it was. Great Buy.

Jay from Boston, MA on 1/7/2016

Awesome amp. The birth certificate shows my amp making 1300 watts rms; how cool is that! 100 watts rms extra for free. I have this amp hooked up using 4 gauge wiring to a 12 inch subwoofer in a ported box; it gets incredibly loud with plenty more left. There are other cheaper amps that claim similar output to this one; don't believe it for a second; they are cheaper for a reason. I am guilty of purchasing those amps. Never again. Thanks again Crutchfield; your customer service, technical support, and return policies are the envy of other Internet sellers.

Pros: Great amp for its price. Super powerful Compact sizing Easy to use

Cons: Wished I would have purchased it before.

Rockford Fosgate R1200-1D

DirkNBer from Meridian, MS on 7/26/2013

Verified customer (What's this?)
Verified employee purchase (What's this?)

Upon deciding I was going to install a complete RF system, the first factor was above all else, clear, crisp sound. I have this R1200-1D pushing 2 Rockford Fosgate P3 12" subs. Having the right equipment, such as the Rockford Fosgate 3Sixty.3 signal Processor with the R1200-1D turns this meek little entry-level amp into a purebred BEAST! As I mentioned prior, great sound quality is a MUST. The R1200-1D has managed to deliver the BEST quality sound out of my system to date. I am 44 yrs young, and have been installing high-end systems for over 20 years. For the money, the R1200-1D cannot be beat!

Pros: small footprint, but huge sound.

Cons: No internal fuses. Design leaves something to be desired in the fact that you can see all wires leading in & out of unit. Personally, I feel they could've put more thought into designing a plate to conceal wires.

Bought this amp to power a Kicker CVT-10 Shallow mount sub in my F-150 Supercrew and it does an outstanding job. Powerfull Amp yet very clear sound. Makes my one 10 hit so hard it sound like two 10's. Well worth the money.

Pros: Size, very small yet a ton of power. Doesn't get very warm when pushing it hard.

Cons:

I just bought this amp a few days ago and so far i've enjoyed it. With this amp and a 12' alpine it seems to hit very hard but at the same time very clear and consistent

Pros: Great control of the subs and sounds great

Cons: No fuse in the actual amp itself. I always love to have a fuse at the amp and 2 in the middle

Features

Overview: The Rockford Fosgate Prime R1200-1D is a mono Class D amplifier. It is optimized to power subwoofers, and is 1-ohm stable. The Class D design is very efficient with a cast aluminum heatsink to keep it in a small footprint. The amplifier has 85% average efficiency at 4-ohms or 2-ohms, and 80% at 1-ohm.

CEA 2006 Compliant: The R1200-1D's power ratings are measured according to the strict standards dictated by the Consumer Electronics Association (CEA). These standards allow you to accurately compare the rated power output of all CEA 2006-compliant amplifiers, even different brands. Manufacturers who adhere to the standards can display the CEA 2006 logo on their products and packaging. The RMS power output is as follows (measured with a 14.4 volt input, <1% THD+N, 20 Hz-250 Hz):

  • 4-Ohm: 400 watts x 1
  • 2-Ohm: 800 watts x 1
  • 1-Ohm: 1200 watts x 1

LED Indicator: The amplifier is equipped with a top-mounted LED indicator which illuminates blue when the unit is turned on. The LED illuminates red when a protection circuit engages (short circuit or too low an impedance is detected at the speaker connections). The amplifier automatically turns off if this occurs.

Mounting: The amplifier can be mounted vertically, horizontally, or inverted using the supplied mounting screws; horizontal mounting (right side up) will provide the best cooling.

Controls

Amp Controls: The R1200-1D has the following top-mounted controls:

  • Gain Control: a rotary gain control that can be adjusted from 1 to 11
  • Low Pass Filter: a 12 dB/octave Butterworth low pass filter with a crossover point variable from 50 Hz to 250 Hz
  • Infrasonic Filter: a variable 15-40Hz, 12 dB/octave infrasonic filter designed to prevent frequencies below the audio range from being applied to the subwoofer
  • Punch EQ: a rotary bass boost control, centered at 45 Hz, from 0 dB to +18 dB

Remote Punch Level Control: The amplifier includes a wired Remote Punch Level Control, which is linked to the gain control of the amplifier. The module allows you to remotely control the output level of the amplifier from the dash or center console of your vehicle. The Remote Punch Level Control features a rotary dial, and comes with mounting hardware and a 16.5' connector cable.

Connections

Terminals: The amplifier features heavy duty, nickel-plated set-screw terminals. The set screws can be tightened or loosened with the supplied 3mm Allen wrench. The terminals include:

  • Power/Ground: will accommodate up to 4-gauge wire
  • Remote Turn-On: will accommodate up to 8-gauge wire
  • Speaker Terminals: will accommodate up to 8-gauge wire. Two Positive (+) and Negative (-) terminals are provided for installation flexibility. Both terminals are wired in parallel internally.

Fuses: The amplifier does not have on-board fuses. A 100A fuse should be placed on the power wire within 18" of the battery.

RCA Input Jack: The RCA input jacks are nickel-plated to resist signal degradation caused by corrosion.

RCA Pass-Thru Jacks: The nickel-plated RCA pass-thru jack provides a convenient source for daisy-chaining an additional amplifier without running an extra set of RCA cables from the front of the vehicle to the amplifier location.

I have (2X) P3 Shallow DVC 2Ohm 12in 400W RMS. I think I have them wired to 2 Ohm and one connected to each channel is that still 2Ohm since it's internally bridged.?

If you have each speaker connected to one channel the amplifier would see one ohm
[ Nicholas  Jul 13, 2019 ]
A
Ismael, if you have each sub wired in series to make the impedance 4-ohms per sub, and then connect each sub to its own terminals, you will have a final impedance of 2-ohms, and get 800 watts ( 400 per sub).

Q
I have a single p3 12 inch dvc at 4 ohms. I understand the amp is 800 watts at 2 ohms, is that too much power for my single subwoofer. Iâ??ve been told the Rockford subs can take way more power than advertised. Is this true???
[ David  Dec 30, 2017 ]
1 answer
A
You can have some excess wattage from an amplifier when you set the gain correctly. Doing so will run the amp below it's full capacity allowing it to operate cleaner, cooler and last longer.

It's very simple; you'll connect the positive & negative terminals of the sub to the matching positive & negative terminals of the amplifier. https://images.crutchfieldonline.com/ca/learningcenter/car/subwoofer_wiring/1SVC_4-ohm_mono.jpg I hope that helps.

I HAVE --ROCKFORD FOSGATE R1-2X12 - 2 12 INCH SUBWOOFERS @ 400RMS / 800 PEAK. WILL THIS ROCKFORD FOSGATE R1200-1D AMP BE TOO MUCH POWER OR ENOUGH ????
[ MICHAEL  Nov 08, 2017 ]

For best sound quality, we recommend getting an amp that doesn't output any more that 150% of the subwoofer's top RMS watts that it can handle. That being said, adjusting the gain as Austin mentioned will allow you to use this amp with your subwoofers because when this amp is turned down, it will not output enough power to blow your subwoofers. Feel free to call an advisor on 1-800-324-9695 for a personal recommendation on an amp. My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=101

Q
I'm running (2) 12" Alpine type R's (4 ohm DVC) @ 1ohm powered by a Rockford Fosgate R1200-1D amp @ approximately 34-40 hz. I switched to a ported enclosure (Rockford Fosgate) that fell into the Type R specs. I have them inverted, mainly to keep them cooled down. My power and ground(which is grounded very well with paint sanded off) both zero gauge. I did the big 3 upgrade using all zero gauge also. Im currently only running one battery. I have another one but didn't hook it up because I'm not sure if it would help much. Reason I think that is if my altenator can't keep up with one battery, no way it can handle two. I may be way off thinking of it that way, so if I'm wrong, please spate me the harsh comments. I've had this setup in a few cars and never had issues with dimming headlights. But in current car, 2008 Impala, it's happening. Don't have money for a high power altenator at this time. Not a big fan of capacitors but I bought a 1 farad one to see if it would help. Didn't help at all, so I removed it. So if anyone can help me at all, I really appreciate it. Also, I wondering if I can get more out of my subs? Gains: 34-40hz, punch EQ is about 25% up, infrasonic is about 30hz, and the gain is at 7 out of 11. It seems like can get a lot more out of my subs, but definitely don't want to overpower them. Again, i you'd really appreciate some feedback

I used two AGM batteries (65Ah each). I installed the 22nd one in the rear of the car.
[ Justin  Aug 16, 2016 ]
A
I have two of these amps running 8 subs. The infrasonic should be turned all the way down to avoid damage for one. And I have an oscope. Seven on the gains is way above distoirtion. I have done multiple tests and around three and a half on the gain is where clean signal to the subs starts to go all bad. Also matched batteries is where you would want to go when you get the cash. The second battery helps to level out the draw and allows the smaller altinator to run at a more level rate than jumping up and not able to meet the demands. First lower the the gains and it should help with the lighting.

i would go with 2 kickers or 2 Rockford fosgate p2 also make sure the subs can handle the rms cause they burn out really fast if they are getting to much power

Wired down to 1ohm? Sounds like you sent too much power to your sub. What was the sub RMS rating?
[ William  Feb 06, 2016 ]
A
well i run the 1ohm fosgate sub 12'' 600w rms the trick is you have to set the gain properly if you don't it will fry it.. lets say your sub took 600w rms ,and that equated to 30v which it doesn't, after a bunch of math then you have to set your gain on your amp playing a 50 hrz tone just before clipping your max volume, then adj your gain to 30 volts with a volt meter, or you risk burning all subs up! due to over voltage their are some youtube videos you can find on setting the gain this way . im not worried about it, i don't run mine that hard good luck
[ justin  Feb 06, 2016 ]

I matched my R1200-1D with 2 fockford P2D4-12's. I also have them wired to 1 ohm. Only have had them for a little over a month and the BEAT! U need to match your amps RMS wattage to ur subs. Your amp has 1200 watts RMS at 1 ohm so your subs should have no less than 800 watts RMS together. An amp having a little extra power is a good thing. If u are running just 1 sub then it should have at least 800 watts RMS by itself. Also turn down your gain some. I wouldn't recommend having it over 3 or 4.

I have 2 rockford fosgate p2 wired at 1 ohm gain set around 7 an it sounds amazing couldnt ask for a better setup

Q
How would connect this sub to power one 4ohm DVC 1200 rms subwoofe? Most of the documentations is for 2 subwoofers. When it says 800w RMS @2ohms x 1 channel, what exactly does not mean considering this is a 2 channel amp?? Does it mean each of the channel is 800? From what I can tell this sub is not bridgeable.

I forwarded your question to an Advisor and they responded with the following: The R1200-1 is a single channel amp. With a 4-ohm DVC subwoofer you would be getting 800 watts RMS (you would wire the voice coils in parallel for a 2-ohm load). While this will work, it's not an ideal match for the sub you described. You can find out more info on matching subs and amps by checking out some of our articles here: http://www.crutchfield.com/lg_100/Car-Amplifiers-How-To-FAQ-and-Shopping-Guides.html If you get a chance have a quick call or chat with an Advisor. They'll be able to help you pick out an amp that will match your system and your budget.
