Overview: The Rockford Fosgate Prime R500X1D Class D mono
amplifier is designed to power subwoofers. The Class D design and extruded
aluminum heatsink allows the amplifier to run cool and efficiently, and results
in a small footprint.
CEA 2006 Compliant: The R500X1D's power ratings are measured
according to the uniform standards advocated by the Consumer Electronics
Association (CEA). These standards allow you to accurately compare the rated
power output and signal to noise ratio of 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:
- 4 Ohms: 300 watts RMS x 1 at 4 ohms, 14.4 volts, and
less than 1% THD+N
- 2 Ohms: 500 watts RMS x 1 at 2 ohms, 14.4 volts, and
less than 1% THD+N
- S/N: 80 dB, measured at 1 watt output (100 dB measured
at rated power)
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 R500X1D 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
- 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 AWG power and
ground wires. (Rockford Fosgate recommends 8 AWG minimum.)
Fuse: An external 50-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 50-amps, the original
should be replaced with a 50-amp fuse. When not using a wiring kit, the
v6-MANL fuse holder (item number
120MANL, sold separately) and MANL50 50-amp fuse (item number
120MANL50, sold separately) can be used.
- 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
- 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.
- Width: 8-1/2"
- Height: 2"
- Depth: 7-3/8"
Enclosure: The Rockford Fosgate Prime R1-1X10 is a sealed
enclosure constructed of 5/8" MDF (Medium Density Fiberboard). The enclosure is
covered with high density black carpeting. The sealed enclosure features high
current compression terminals on the left side of the box (when facing the
woofer). The terminals will accommodate up to 12 AWG speaker wire and present a
4-ohm load to your amplifier.
- Width: 16"
- Height: 12-1/8"
- Depth (base): 12-1/8"
(12-7/8" including the subwoofer)
- Depth (top): 7-1/8"
(7-7/8" including the subwoofer)
Woofer: The R1-1X10 enclosure is loaded with a single
Rockford Fosgate Prime R1S4-10 subwoofer. The R1S4-10 is a 10-inch, 4-ohm single
voice coil subwoofer with a fiber reinforced painted paper-pulp cone and
compressed foam surround.
CEA-2031 Compliant: Power handling on the Rockford Fosgate
Prime R1S4-10 subwoofer conforms to CEA-2031 industry standards. This means the
subwoofer has the capacity to handle its rated power under continuous demand,
not instantaneous power handling, that over time, can damage voice coils.
