Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
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'
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
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.
