About the Rockford Fosgate Prime R150X2
Rockford Fosgate power for your speakers
Rockford Fosgate performance in an affordable package — the Prime Series R150X2 2-channel amp can drive a pair of speakers with 50 watts RMS each, so you'll really feel your tunes rockin'. Or, you could switch the R150X2 to 1-channel mode to run a sub with 150 watts RMS — when you buy a bigger amp for your subs later on, you can still use this 2-channel to drive your front speakers. Smart move.
You can use the high- and low-pass filters and Rockford Fosgate's famous Punch boost to get maximum performance from the speakers in your vehicle. And speaker-level inputs let you hook this amp up to almost any system, even a factory stereo.
Rugged performance and value
The R150X2's heavy cast-aluminum chassis efficiently draws damaging heat away from its internal components, ensuring reliable, long-term play. The amp's built-in sensors keep track of the output current and power supply temperature, ensuring that plunging speaker impedances (they change constantly during play) or even a short circuit won't hurt anything. Your driver's seat will become your favorite place for listening to music once this Prime amp goes to work.

Overview: The Rockford Fosgate Prime R150X2 2-channel amplifier is designed to power a set of full-range or component speakers. The amplifier can also be bridged to power a single speaker.
CEA 2006 Compliant: The R150X2's power ratings and signal to noise ratio are measured according to the uniform standards advocated by the Consumer Electronics Association (CEA). This allows you to accurately compare these specifications for 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: 50 watts RMS x 2 at 4 ohms, 14.4 volts, and less than 1% THD+N
- 2 Ohms: 75 watts RMS x 2 at 2 ohms, 14.4 volts, and less than 1% THD+N
- Bridged: 150 watts RMS x 1 at 4 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 the RCA inputs, 450mV to 12V when using the speaker level inputs.
Crossover: The amplifier is equipped with a 12dB/octave Butterworth crossover. A crossover switch allows you to choose low-pass, high-pass, or full-range operation. The crossover point is continuously variable from 50 to 250 Hz.
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 gauge power and ground wires.
Fuse: An external 20-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 20-amps, the original should be replaced with a 20-amp fuse.
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 two pair of speaker outputs are nickel-plated set screw terminals what will accommodate up to 8 AWG speaker wire.
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.
