Rockford Fosgate performance in a small package. The Prime Series R250X1 mono amp can drive a sub with up to 250 watts RMS, so you can really feel your bass rockin'. You can use the low-pass filter and Rockford Fosgate's famous Punch boost to get the best possible bass from the sub and enclosure in your vehicle. A phase switch gets your subs firing along with your other speakers for maximum impact, while the speaker-level inputs let you hook this amp up to almost any system, even a factory stereo.
The R250X1's heavy cast-aluminum chassis efficiently draws damaging heat away from its internal components, ensuring reliable, long-term play. The amp's built-in sensors keep track of the output current and power supply temperature, ensuring that plunging subwoofer impedances (they change constantly during play) or even a short circuit won't hurt anything. The included wired remote lets you control the amp's volume level from the front seat. Your driver's seat will become your favorite place for listening once this Prime amp goes to work.

Pros: Power controls
Old school rocker Fosgate in my eyes the best sub amps
Pros: Neverhad one burn up tough amp Rockford Fosgate the best
Cons: Alsom sound and a lot ot of it lol
A great amp and price for my subwoofer.
Pros: Easy installation
Opened, installed and up and bumping in no time. Performed up to expectation.
Pros: Easy install, performs as expected.
Great amp for a great price! Doesn't radiate a lot of heat, just a bit warm after a lot of use.
Pros: Easy installation, looks clean
I used this amp to power an 8" bazooka tube. The thing sounds great! The crossover adjustments are easy to use and installation was just as easy. I like the remote bass boost knob too!
Pros: Easy to install and tune.
I bought this amp to drive the factory sub in my Honda Ridgeline when upgrading the factory head unit to a new one. That being said, I didn't need much by way of power, but I also wanted something good quality, since I had to tear about the entire back end of my truck's cab to put it in. (The factory sub is inaccessible without removing the rear seat - bolts and all.) Nice touch adding the remote control for the bass level - especially considering the fact that once I put the seat back I don't have access to adjust it.
Pros: - Good quality (sound and build) - Remote level control
Cons: - No Complaints
One of the best amps around. The service was great by Crutchfield. They suggested this amp and it is the perfect set up.
Great product. Provides great power to my sound system. Items were delivered on time.
Great amp, powering a 12" audiobahn, love the remote bass punch it comes with for fine tuning without going to the trunk. Has plenty of power for my ears.
Pros: Remote with plenty of cord for fine tuning the bass punch, plenty of power for such a small amp
Cons: Haven't found any cons yet
Big performance from a little guy
Pros: Plenty of adjustments for fine tunning
Great amp for the price and easy to install
Pros: Sounds great, easy to install and it won't break your bank.
Very easy to attach to your vehicle, not cheaply made either!!! Hook up to your system couldn't be easier. Simple to adjust and tune once it's connected!
Pros: Small compact size, inexpensive, easy to fine tune, connecting to your system was simple!
Cons: Not much to complain about, you get exactly what you pay for.
Provides just the right amount of power to the sub I purchased
Pros: Size isn't big at all. After the right adjustments, sounds great
Cons: Honestly can't think if any.
This is my first install of any amp. I think I choose wisely! If I had the extra money, I woulda went 4ohm mono at 250rms or more, but that gets expensive. Running at 2 ohms loud, it starts to get hot sooner than later. But good bang for the dollar! Highly recommended.
Pros: Nice and small, Allen wrench on every terminal! Loved that. Made it easier for me. No matter how ya mount it, easy access to adjustments.
Cons: Not one.
I've never have a small amp that said that it was 250 watts actually do it. I tested this amp and it was putting out 345 watts. I've got it running a single Rockford Fosgate P1 10inch sub in a ported box and it gets loud. I've had others ask me if its 2 12 inch subs.
Pros: Puts out more power than stated, very compact size, easy installation, looks good
Cons: None that I can think of

CEA 2006 Compliant: The R250X1's power ratings and signal to noise ratio are measured according to the uniform standards advocated by the Consumer Electronics Association (CEA). This allows you to accurately compare these specifications for all CEA 2006-compliant amplifiers, even from different brands. Manufacturers who adhere to these standards can display the CEA 2006 logo on their products and packaging. CEA2006 Specifications for this amplifier are:
LED Indicator: The amplifier is equipped with an LED power/protect indicator. The LED illuminates blue when the unit is turned on. It illuminates red if the thermal or short circuit protection circuit is engaged, and the amplifier will automatically turn off.
Mounting: The amplifier can be mounted vertically or horizontally using the supplied mounting screws. The amplifier should never be mounted in an engine compartment as this will void the warranty.
Gain Control: Use the amplifier's gain control to match the output of the source unit. The rotary gain control is labeled 1 to 11 and has a sensitivity range of 150mV to 4V when using a preamp level signal, 450mV to 12V when using a speaker level signal.
Remote Punch Level Control: The R250X1 includes a wired Remote Punch Level Control, 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. The Remote Punch Level Control features a rotary dial, and comes with mounting hardware and an 18' cable.
Note: The Remote Punch Level Control measures approximately 1-3/4" wide (2-5/8" including the mounting flange) x 3/4" high x 1-5/8" deep (2-1/8" deep including the knob and wiring).
Crossover: The amplifier is equipped with a 12dB/octave Butterworth low-pass crossover. The crossover point is continuously variable from 50 to 250 Hz. This being a subwoofer amp, the crossover is always engaged.
Phase: The 2-position phase switch allows you to easily reverse the output phase of the amplifier, choose 0° or 180° to match the rest of your vehicle's speaker system.
Punch EQ: The Punch EQ bass boost circuit is adjustable from 0 (min) to +12dB (max) and centered at 45Hz.
Power Terminals: The power and ground terminals are nickel-plated set screw terminals and will accommodate up to 4 gauge power and ground wires.
Fuse: An external 30-amp fuse (not included) must be installed on the power wire at the battery. If a wiring kit is used which includes a fuse with a value other than 30-amps, the original should be replaced with a 30-amp fuse.
Remote Turn-On Terminal: The remote turn-on terminal is a nickel-plated set screw terminal that will accommodate up to an 8 AWG wire. It's used to remotely turn the amplifier on and off.
Speaker Terminals: The one pair of speaker outputs is nickel-plated set screw terminals what will accommodate up to 8 AWG speaker wire.
RCA Input Jacks: The industry standard RCA jacks provide an easy connection for preamp level input. They are nickel-plated to resist signal degradation caused by corrosion.
Speaker Level Input: A speaker level input harness is included, making it easier to add the amplifier to a factory radio or to a receiver with no preamp outputs.
RCA Output Jacks: A pair of RCA pass-thru jacks provides a convenient source for daisy-chaining an additional amplifier without running an extra set of RCA cables from the front of your vehicle to the amplifier location.
Wired Remote: An RJ-25 jack is used with the included Remote Punch Level Control.

Replacing a failing RF punch 301M [ JASON M Sep 15, 2016 ]
Good match for the sub I purchased. [ Willie Jul 16, 2016 ]
Fits my specific need. [ Albino Jun 28, 2016 ]
Because it's Rockford [ Eric C. Jun 04, 2016 ]
Good price for an amp from an established brand. [ Miguel May 19, 2016 ]
Awesome power for dollar amount! [ Tim May 08, 2016 ]
it was recomended [ Charles Mar 31, 2016 ]
Seems to be a good choice for the Rockford Fosgate R2S-1X10. We currently have 4 other Fosgate amps in different vehicles that have performed well. [ GARY Mar 26, 2016 ]
Small size, plenty of power. [ Curtis Jan 29, 2016 ]
Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Krissy May 05, 2015 ] Staff
A 2-ohm punch 12 would be a great match: http://www.crutchfield.com/p_575P1S212/Rockford-Fosgate-Punch-P1S2-12.html [ Jeff Dec 15, 2014 ] Staff
4 gauge is also necessary unless, you want to blow fuses in the line or heat up the wire. [ John Dec 03, 2014 ]
Yes. I used Sky High 4 gauge OFC and it fit perfectly. [ John Dec 03, 2014 ]
Yes. I believe larger than 8 guage wiring is required. $ guage would be overkill, but fine technically. You may have trouble fitting it into the ports but they probably have ends that can be crimped on. I am pleased with the output though. Good amp, especially for the price. [ STEVEN Dec 03, 2014 ]
I wouldn't recommend it it will heat up if you like volume. [ JARED Dec 03, 2014 ]
I forwarded your question to an Advisor and they responded with the following: It would not be recommended to use a 10 gauge. The amp calls for an 8 gauge as the minimum size. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy Aug 06, 2014 ] Staff
