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 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 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.
