Our take on the Rockford Fosgate R250-2x12

by Jo Greene

Prime Series powered subwoofers are all-in-one bass solutions that deliver phenomenal bass. Rockford Fosgate combines a potent mono amp with power-matched subs for serious performance, then houses them in an enclosure designed for hard-hitting bass output. Industrial grade carpet protects the box, along with the interior of your trunk, from nicks and scratches.

Two hefty 12" subs
The R250-2x12 powered sub features two Prime 12" subs that use rigid polypropylene cones and butyl rubber surrounds to punch out powerful deep notes. Stamped solid-steel frames ensure long life, even under heavy fire, while the aluminum voice coil formers dissipate heat efficiently when you're pushing your system hard. These subs are optimized for sealed enclosures, so you can expect highly accurate low end to complement your music.

250 watts RMS and a rugged enclosure
A rugged sealed enclosure built from 5/8" medium density fiberboard houses the two 12" subs. A Prime R250-1 amp, mounted on the back of the enclosure, sends 250 watts RMS to the two subs for strong punch, and patented circuitry keeps your bass clean even when you put heavy demands on your system. An included wired remote gives you volume control from your front seat.

Highlights:

amplified dual 12" subwoofer enclosure
two Prime 12" 4-ohm subs with polypropylene cones and butyl rubber surrounds
Prime mono Class AB amplifier (250 watts RMS at 2 ohms)
5/8" medium density fiberboard sealed enclosure with carpet covering

Mono-Channel Amplifier
Dual 12-inch Preloaded Subwoofer Enclosure

Mono-Channel Amplifier

CEA 2006 Compliant: The Rockford Fosgate R250-1 Prime'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 if they come from different brands. Manufacturers who adhere to the standards can display the CEA 2006 logo on their products and packaging.

4-Ohm Mono: 150 watts RMS x 1-channel in 4-ohm @ 20-130Hz with 1% THD
2-Ohm Mono: 250 watts RMS x 1-channel in 2-ohm @ 20-130Hz with 1% THD

Note: The amplifier will operate in a 2-ohm load to power the included preloaded subwoofer enclosure.

MOSFET Power: The Rockford R250-1 is equipped with a MOSFET power supply and output stage for good sound, efficiency and dependability.

Controls: The Rockford Fosgate mono-channel amplifier is equipped with the following controls.

Gain Control: The amplifier's gain control is preset to match the output of most source units. The gain control can be adjusted from 150mV to 8V.
Low-Pass Crossover: The amplifier features a built-in 12dB/octave Butterworth low-pass filter with a crossover point variable from 40 to 130Hz.
Phase: The phase switch allows you to select the output phase of the amplifier between 0-degrees and 180-degrees to match the rest of your vehicle's speaker system.
Punch Bass: This is a Punch bass control on the amplifier that is adjustable up to 12dB at a fixed 45Hz.
Remote Punch Level Control: When the wired remote Punch Level Control is connected to the R250-1, the gain control of the amplifier is linked and allows you to remotely control the output level of the amplifier from the dash or center console of your vehicle. The wired remote Punch Level Control module features a rotary dial can comes supplied with mounting hardware and a 16.5' connector cable.

Note: The amplifier's low-pass crossover can be set between 40 to 130Hz to accommodate the included preloaded 12" subwoofer enclosure.

Connections: The Rockford Fosgate R250-1 is equipped with the following connections

Power/Ground Terminals: The power and ground terminals are nickel-plated screw terminals and will accommodate up to 4 AWG power/ground wire (up to 1/2" spade or ring-style connector).
Remote Turn-On Terminal: The remote turn-on terminal is a nickel-plated screw terminal that will accommodate up to an 8 AWG wire (up 3/8" spade or ring-style connector). This terminal is used to remotely turn-on and turn-off the amplifier when +12V DC is applied, when connected to your headunit's remote turn-on lead. .
Speaker Terminals: The amplifier is equipped with two pairs of speaker terminals for an easy parallel subwoofer connection. The four speaker terminals (left +/- and right +/-) are heavy duty, nickel-plated screw-terminals what will accommodate up to 8 AWG speaker wire (up to 3/8" spade or ring-style connectors).
RCA Input Jacks: The industry standard RCA jacks provide an easy connection for signal level input. They are nickel-plated to resist signal degradation caused by corrosion.
RCA Output Jacks: This pair of RCA pass-thru jacks provide a convenient source for daisy-chaining an additional amplifier without running an extra set of RCA cable from the front of your vehicle to the rear amplifier location. They are nickel-plated to resist signal degradation caused by corrosion.
Punch Level Control: 3.5mm input for connecting the supplied Punch Level Control module.
Fuse: The amplifier is equipped with one installed 30-amp ATC fuse. The amplifier also comes supplied with a spare 30-amp fuse.

Note: The amplifier only requires one set of speaker terminal connections to the included preloaded subwoofer enclosure.

LED Indicators: The Rockford Fosgate amplifier is equipped with two side-mounted LED indicators.

Power LED: This LED illuminates green when the unit is turned on.
Protect LED: This LED illuminates red if a short circuit or too low of an impedance is detected at the speaker connections. The amplifier will automatically shut down if this occurs.

Mounting: The amplifier comes pre-mounted to the included subwoofer enclosure.

Dual 12-inch Preloaded Subwoofer Enclosure

Sealed Enclosure: The Rockford Fosgate Prime R1L-2X12 features a sealed enclosure constructed of 5/8" MDF (Medium Density Fiberboard). The enclosure is covered with high density black carpeting.

Note: The included mono-channel amplifier is pre-mounted to the back of this subwoofer enclosure.

Speaker Terminals: The sealed enclosure features high current compression terminals on the left side of the box (when facing the woofers). The enclosure's terminals will accommodate up to 12 AWG speaker wire. The two loaded woofer's are wired in parallel to present a 2-ohm to the connected amplifier at the enclosure's speaker terminals.

Dual Woofers: The R1L-2X12 features two loaded Rockford Fosgate Prime R1S412 woofers. The Rockford Fosgate Prime R1S412 is a 12-inch, 4-ohm single voice coil subwoofer. The Rockford Fosgate Prime subwoofer features a solid stamped steel frame, quick-release compression terminals, and a Parabolic polypropylene cone. The Prime R1S412 subwoofer is optimized for sealed enclosures.

Parabolic Polypropylene Cone Design: The Parabolic Polypropylene cone design results in solid bass reproduction.
Aluminum Voice Coils: The Rockford Fosgate Prime subwoofer uses anodized aluminum voice coil formers that provide excellent heat dissipation. The woofer's aluminum voice coils keep the speaker running cool, even under demanding conditions. Unlike traditional plastic substitutions, aluminum acts like a heat-sink to quickly dissipate thermal build-up on the voice coil. This keeps subwoofers cool during high SPL conditions.
Stamped Steel Basket: The R1S412 subwoofer features a stamped steel basket for added rigidity.
Compression Terminals: The Prime R1S412 features spring post terminals which accommodate up to 12 AWG speaker wire.
CEA-2031 Compliant: Power handling on the Rockford Fosgate Prime R1S412 subwoofer conforms 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.

I am so satisfied with my subs and Crutchfield overall. I drive a Celica and the Rockfords perfectly fit with the stock 8 speakers. In addition, the included directions allowed me to install it relatively easily with little to no hassles. Great buy!

It was a nice system and I would definitely tell m friends about it who are just beginning and want to tweak their systems but just not sound hogs who want to make a real statement.

Pros:

It was cheap for such size. Had good punch and made the passengers happy (especially the ones in the back)

Cons:

For you people like me who want to crank the levels and really make a scene then I would advise upgrading the amplifier.

These speakers put out huge sound for the money. I have had several stereo systems and highly recommend this product. The earth won't crumble around you, but these speakers will give you plenty of bass for the buck. I put these in my 2007 Jeep Grand Cherokee and they have definitely completed my system. The remote bass knob is a great touch for control from the drivers seat. Rockford Fosgate has done it again with this great set up.

Pros:

Remote bass knob, sounds great, fairly compact. Easy installation, wire and play.

Cons:

will bottom out if you push them too hard.

plenty of bass

Crutchfield Customer Review

The reviewer purchased this item from us, verified by the email address on the order.

I replaced an MTX sub and box due to it blew...The Rockford Fosgate box fit in between the hole to where my seats fold down in my 2010 Taurus SHO perfectly. Even with the seats up this system really puts out the bass. I have the factory 360 watt Sony system and the Subs really added the punch that it was lacking. I have an 18 year old son and he was even impressed with his old man's system. He takes his friends out to the garage and rock out sitting inside the car with the windows up!

Pros:

fit perfectly and was priced right.

Cons:

no longer can use the extra cargo room by folding the seats down...but the extra bass was worth it.

This is a good mid level system for the average guy that has never had a good set up. The guy who has had a trunk shaker this will not impress you and you will need to spend some more cash to be satisfied

Pros:

friendly on the budget

cheap sound

The type of bass you get from your component subwoofer doesn't depend on the woofer alone. You'll need a strong, tightly constructed enclosure for optimum subwoofer performance.
