You won't believe how small and powerful this amp is. Rockford Fosgate's PBR500X1 mono amp can drive up to 500 watts RMS into a 1-ohm load, allowing you to power multiple subs to get more bass. And this Punch Class BR amplifier generates this power from a very tiny case — literally the size of your hand.
Boosted Rail (BR) amp technology uses capacitors and high-speed circuitry to boost the amp's power supply voltage when needed, so it can handle massive 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.
Add Rockford Fosgate's PEQ wired remote, and you'll be able to control the subwoofer impact from your front seat. 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.
Super compact amp that drives with a good deal of power. As with most Rockford amps, they provide a test sheet that shows the amp performing above the listed specs. Very low power draw on your vehicle, but pushes my JL sub perfectly. I have used this amp with several different setups and subwoofers with virtually no issues. Amp will run stable at 1ohm and push +500 watt rms. Only issue some may encounter is that they need to be smart on where it's mounted. Amp runs hot when being driven, but does not shut down. Downside is that it could melt plastic or nylon carpet if not thought out on installation.
Pros: Great power in a very small footprint
Cons: Can run hot, limit certain install locations
First let me say that the PBR500x1 is a great amp. I have a 2011 Lexus ES350 with ML and I needed a amp that I could install on the bulkhead support under the rear deck shelf. I was just looking to add bass to my ML system, I don't need for the sound to win db awards or astound pedestrians. I hooked this up to a Audio Control LC2i both installed on the bulk head support. I did this as I need space for all the things I need to carry with two kids and wanted a clean and small install to save space and not to be exposed to damage. The amp is very powerful, don't let the size fool you, the birth sheet that came with my amp showed 360 watts at 2ohms and it definetly feels like it. I have the gain only on 1/3 of the way and hooked up to a JL HO ported 10" box and the combo rocks the car, the amp can definetly push more power and larger subs then I am using. The sound is clean and there is no turn-on/off thumps. If I turn up the gain the power is unbelievable and even without the back seat passthrough open you can still feel the sound waves. I highly recomend this amp to those who need a stealth install without sacrificing sound quality. I would of rated it 5 stars but the controls are very small and hard to read/adjust but that is the price you pay for the small form factor, which is acceptable. Having said this, I would definetly by it again as the small controls are not a issue once you get everything dialed in. Buy this amp, you won't be disapointed.
Pros: Small size, fits just about anywhere Powerful output Flexible design (high/low level with high level sensitivity adjustment) Clean sound Does not get hot No turn on/off thump
Cons: Controls are small (small price to pay) High level connection is via a external RCA wire kit (small price to pay)

Boosted Rail Technology: The PBR500x1 uses Boosted Rail Technology (BRT), an efficient design that doesn't use a switching power supply. The PBR500x1's average efficiency is more than 75%, meaning it doesn't generate much heat and can maintain a small footprint.
Power Output: The power output increases as impedance is reduced:
Signal Input: The PBR500x1 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.
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).
Power Connections: The power, ground, and remote turn-on terminals are c-clamps on a removable plug. Each terminal will accommodate up to 8-gauge wire (Rockford recommends 8-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 80-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 80-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 used.
Speaker Output: The speaker outputs are c-clamps on a removable plug. Each terminal will accommodate up to 8-gauge wire
Remote Punch EQ (PEQ): An RJ-45 jack is provided for connecting an optional remote PEQ control (575ROCKPEQ, sold separately). When connected the PEQ acts as a variable bass boost; 0-18 dB centered at 45 Hz.
Note: Older model (prior to 2007) Punch Bass and Para-Punch remotes will not work with this amp.
