You won't believe how small and powerful this amp is. Rockford Fosgate's PBR300X2 2-channel amp puts out 100 watts RMS each to a pair of speakers, all from an amp you can easily hold in one hand. You can also put this amp in one-channel mode to drive a sub with 300 watts RMS of bumping bass. And an optional wired remote control lets you add Rockford Fosgate's famous extra Punch from the front seat.
This Punch Class BR amplifier uses Boosted Rail (BR) amp technology to generate so much power from such a tiny case, with capacitors and high-speed circuitry that boost the amp's power supply voltage when needed, so it can handle musical peaks without missing a beat. Rockford Fosgate uses this new technology to create a remarkable amp that fits almost anywhere and delivers powerful sound.
The amp also features speaker-level inputs with signal-sensing turn-on, allowing you to connect into almost any system without having to run a turn-on lead back to the receiver. An extruded aluminum heat sink combines with Rockford Fosgate's heat management technology to make sure your tunes keep rockin' even when you're playing loud.
You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.
This is a great little amp... Only had three problems, the amp does tend to run very hot,the speakers I bought with the amp can't handle the power. Had to turn the amp all the way down . In the process of trying to find some speakers that will work well with this amp! And the biggest , is that I what I paid for this amp and I see it for $100 less everywhere!
Pros: Great power
Cons: Finding speakers to run with it , and the price.
Acceptable for an average system. Not suitable for an audiophile quality system. Runs hot when driven hard. Very warm when idling. Clips and distorts when driven hard, had to turn the gain down, killing the little bit of kick the PBR300x2 had, and severely reduced the volume level. This was to replace my 35 yr old 15 watt x2 amp. The old unit has more kick, and same dB volume w/o clipping or distortion. With a rating of 100 watts into 4 ohms, the PBR300x2 amp should have easily driven an 8 ohm load albeit at a lower volume. Measured dB level was the same as my vintage 15 watt x2 amp. .Bridging the PBR300x2 amp into a 4 ohm load only slightly raised the dB level. Bridging the PBR300x2 into a 4 ohm load produced slightly more volume, and did not improve any of the other parameters mentioned. The PBR300x2 was no better than my old 15 watt x 2 amp.
Pros: Excellent Small size package. Acceptable for an average system.
Cons: Runs hot when driven hard. Very warm when idling.. Clips and distorts when driven hard unless the gain is trimmed. Trimming the gain to eliminate clipping and distortion noticeably reduced the volume level.
Product is easy to install, easy to hook up and produces very clean,low distortion sound in all adjustment ranges.
Perfect amp, perfect size. I installed this amp on my 2014 street glide, I have it powering the two front speakers, and it works perfect!
Pros: Small size but lots of punch!
Cons: Does seem to get a little warm! But have not had a problem.
Very powerful, very small, great product

Boosted Rail Technology: The Rockford Fosgate PBR300x2 uses Boosted Rail Technology (BRT), an efficient design that doesn't use a switching power supply. The PBR300x2's average efficiency is more than 75%, meaning it doesn't generate much heat and can maintain a small footprint.
CEA 2006 Compliant: The PBR300x2's power ratings are measured according to standards provided 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. These CEA2006 Power Specifications are measured at 20-20kHz, 14.4 V, and 1% THD+N:
Signal Input: The PBR300x2 is compatible with either line-level (RCA) or speaker-level inputs. The included Molex-to-RCA is used in both cases; the RCA end is cut off for connection to speaker wires.
Auto Turn-on: When using speaker-level inputs the amp will automatically turn on when it senses an input signal (4 volt minimum). The threshold voltage (DC offset) for auto turn-on is adjustable from 4 volts to 6 volts. This circuit is only active when the Input Level switch is set to High (speaker-level).
Dynamic Thermal Management (DTM): DTM evenly distributes excess heat across the entire extruded aluminum heatsink. This helps to keep internal components cool, thus increasing efficiency, reducing distortion, and maximizing the potential of all components.
MEHSA³: MEHSA³ (Maximum Efficiency Heat Sink Application-Third Generation) is a Rockford Fosgate proprietary process that increases the heat transfer from the MOSFET devices to the heatsink. The multi-layer insulated metal MEHSA substrate operates with minimal thermal resistance, spreading heat both downward and outward to quickly dissipate heat from each device across the heatsink. This allows greater power output, enhanced thermal stability, and maximum reliability.
NOMAD: NOMAD (NOn-Multiplying Advanced Decision) is an intelligent protection circuit that uses an analog computer to make real time decisions regarding temperature, voltage, current and impedance. The unit is protected without limiting sound output unless needed.
DSM (Discrete Surface Mount): In the manufacturing process high speed robotics are used to place 1% tolerance parts and large board traces. DSM improves the efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.
LEDs: The Power/Protect LED on the right side of the amp illuminates blue when the amp is turned on and operating normally; it illuminates red when one of the protection circuits has engaged (short circuit, impedance too low, or temperature too high). The BRT LED on the left side of the amp illuminates white when the boost mode is engaged.
Crossover: The amplifier's internal low-pass crossover is continuously variable from 35 Hz to 250 Hz; the slope is 12 dB/octave.
Gain: When using line-level inputs, the input gain is adjustable from 150mV to 4V, when using speaker-level inputs it's adjustable from 400mV to 11V.
Input Level: Use the 2-position switch to select the input voltage range; High (speaker-level) or Low (line-level).
DC Offset: The DC offset threshold voltage for the auto turn-on circuit is adjustable from 4 volts to 6 volts (feature only active when the Input Level switch is set to High).
Punch EQ2: An RJ-45 jack is provided for connecting an optional remote PEQ control (575ROCKPEQ, sold separately). When connected, the Punch EQ2 on-board equalization circuit is activated to help correct inherent acoustical deficiencies in the automobile listening environment. When the amp's Crossover Switch set to Low-Pass operation, the Punch EQ2 circuit provides a variable Bass Boost. When set to High-Pass, it acts as a variable Mid-Bass and Treble Boost. Both Bass and Treble frequencies are boosted when the amp is set to All-Pass operation.
Power Connections: The power, ground, and remote turn-on terminals are c-clamps on a removable plug. Each terminal will accommodate up to 10-gauge wire (Rockford recommends 10-gauge minimum for the power and ground wires). A flat blade screwdriver (not supplied) is required to tighten/loosen the terminals. There is no fuse on the body of the amp, so an external 30-amp fuse (not included) must be installed in the power wire. If a wiring kit is used that includes a different value fuse, the original should be replaced with a 30-amp fuse.
Signal Input: The included input harness has a Molex plug on one end (plugs into the amp) and female RCA plugs on the other. When using speaker-level inputs the RCA end is removed and the four individual wires are spliced onto the head unit's speaker wires.
Speaker Output: The included speaker output harness has a Molex plug on one end (plugs into the amp) and tinned bare wires on the other.
Remote Punch EQ: The amp's RJ-45 jack allows you to connect the optional Remote Punch EQ.
Note: Older model (prior to 2007) Punch Bass and Para-Punch remotes will not work with this amp.
