Rockford Fosgate Prime R250-1
Mono subwoofer amplifier 250 watts RMS x 1 at 2 ohms
Our take on the Rockford Fosgate Prime R250-1 by Crutchfield's Buck Pomerantz
Now you can get Rockford Fosgate performance at value prices. Prime Series amplifiers bring out your music's subtle details as they drive your speakers with the clean power you need to overcome road noise and fill your car with sound.
Rockford Fosgate designed Prime amps to deliver Power Output Without Excessive Regulation (POWER), which means they'll respond quickly to the peak demands that you may put on your system. Your driver's seat will become your favorite place for listening when you add the clarity and impact of a Rockford Fosgate amp.
The R250-1 mono amp powers your subwoofers with up to 250 watts RMS so you will feel the bass. A low-pass filter and Rockford Fosgate's famous Punch bass boost lets you adjust your bass for your enclosure and vehicle. A phase switch gets your subs to work together with the rest of your car's audio system for maximum impact. A wired remote lets you control the amp's volume level from the front seat, allowing you to adjust the bass for different types of music.
Great amp for the money. Lots of power and versatility in a small package. Runs cool @4 ohms. Sounds great. What you would expect from Rockford Fosgate.

Overview: The Rockford Fosgate R250-1 Prime 250 watt mono-channel amplifier is designed to power one or two subwoofers. The R250-1 is designed with specific features to power your subwoofers with a frequency range between 20-130 Hz. This amplifier is not designed to power a full-range speaker.
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
MOSFET Power: The Rockford R250-1 is equipped with a MOSFET power supply and output stage for good sound, efficiency and dependability.
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 can be mounted vertically or horizontally using the supplied mounting screws. The amplifier should never be mounted upside down or in an engine compartment (this will void your warranty).
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 link 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.
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.
