Rockford Fosgate Punch PBR300X2

PBR300X2- 300 Watt Amplifier with Boosted Rail Technology

To achieve higher efficiency with lower distortion, Rockford's BR topology combines, Cycle-by-Cycle, an indirectly coupled high/low voltage rail linear topology with a switched high/low voltage linear rail topology. This combination yields an unsurpassed power density (watts per cubic inch). In addition, this patented technology allows the chassis design to be much smaller than traditional sized amplifier - 1.53" x 4.25" x 6.75" - making this amp a great solution for smaller stealth installations, motorcycles and recreational vehicles. In fact, now, with the introduction of the Rockford Fosgate RFKHD9813, installing the PBR300X2 into select 1998 - 2013 Harley Davidson motorcycles has never been easier. With unparalleled technology, flexible installation options, and big power from such a small footprint Rockford Fosgate has ensured that everyone can put a little Punch in any system.




Punch EQ2

Punch EQ2 - Jim Fosgate's Brainchild

The Punch EQ on-board equalization circuit helps correct the acoustical deficiencies often found in car audio systems. These deficiencies were researched and graphed out by none other than Jim Fosgate himself. From that forward thinking approach, we now have the Punch EQ2. When accompanied by the Optional Remote Punch EQ, the user has full control of a variable bass boost centered at 45 Hz.

MEHSA³

MEHSA³ - Max Efficiency Heat Sink Application

MEHSA3 is a proprietary process that yields up to five times better heat transfer than traditional FET mounting techniques, using the exact same components. A multi-layer insulated metal substrate operating with minimal thermal resistance spreads heat both downward & outward to quickly dissipate heat from each device across the heatsink. This process allows Rockford Fosgate to squeeze more watts per cubic inch from every output device as well as provide consistent thermal stability. The higher power handling results in a 20% reduction in thermal impedance.


DSM - PBR300X1 Model Shown

DSM - Discrete Surface Mounted Components

An industry-leading manufacturing process, DSM utilizes high-speed robotics, high-quality 1% tight-tolerance parts and large board traces. The discrete components are laser etched to meet a particular value and a very low tolerance. This lower tolerance improves the efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature. These superior components are used by aerospace, automotive, and cellular manufacturers.

Power Specifications - Full Range Channels

RMS Power @ 4 ohms

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 4 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

100 watts x 2 channels
RMS Power @ 2 ohms

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 2 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

150 watts x 2 channels
Bridged RMS Power

Bridging refers to combining two channels on an amplifier to create one channel with double the voltage and an increased power output. A 2-channel amplifier will bridge down to 1-channel and a 4-channel amplifier can bridge to create 2-channels. An amplifier is most commonly bridged to drive a subwoofer.

Remember, once you bridge two channels down to one its final impedance will be 4 ohms unless otherwise specified. This rating lists the RMS power created once an amplifier is bridged.

300 watts x 1 channels

Amplifier Specifications

Amplifier Series
This designates the series of the amplifier. Many amps are available in a litany of different wattage and channel configurations, but maintain consistent features throughout the product line.
Punch BR (Rockford Fosgate)
Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.

BR
Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
2
Total RMS Power Output
Total RMS power is measured by multiplying RMS power per channel by the number of channels, and is calculated at the lowest level of operating impedance.

RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.

The RMS output figure is much more accurate than the peak rating when comparing products.

300 watts
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
10 AWG
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
2 ohms
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
4 ohms
THD at Rated RMS Power
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
<1.0%
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Yes
Preamp Outputs
Many amplifiers are equipped with RCA preamp outputs which pass the original music signal from the source to additional amplifiers. This is known as daisy chaining because the source connects to the first amp, and the first amp connects to the second amp, etc. The advantage to daisy chaining is you only need one 2-channel RCA cable to transfer the signal from the head-unit to the amplifier, and then one additional cable for each amp being daisy chained.
No
Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Low-pass (LP)
High-pass (HP)
Full (AP)
High-Pass Crossover Frequency
The high-pass crossover frequency can be a fixed crossover point or a variable crossover range. A variable high-pass crossover allows you to select a specific crossover point which allows frequencies above the set crossover point to pass, while making frequencies below the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

50 - 500 Hz
Low-Pass Crossover Frequency
The low-pass crossover frequency is typically used for subwoofers. It can be a fixed crossover point or a variable crossover range. A variable low-pass crossover allows you to select a specific crossover point which allows frequencies below the set crossover point to pass, while making frequencies above the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

50 - 500 Hz
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
100 dB
Bass/Gain Remote
If the amp comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.
Optional (Accessory required and sold separately)
Fan Cooled
A great feature to have if an amp generates a large amount of heat. Cooling fans can help regulate the temperature to prevent the amp from overheating (burning).
No
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
50A X 1 In-Line Fuse Recommended
Strappable
Some amplifiers can be "strapped" together in order to increase the output of a single audio channel. These amplifiers feature RCA preamp outputs, allowing you to pass the signal directly from one amp to the other to ensure consistency.
No
CEA-2006 Compliant
Amplifiers that have been tested to meet specific standards. When a car amplifier meets these standards, you can be sure that it will be able to produce the amount of power specified by the official CEA-2006 rating. Usually, these rating consist of the following items:
  • RMS Power
  • Signal-to-Noise Ratio

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.

Yes
Sonic Certified Amplifier
Sonic Certified amplifiers have been tested by the experts at Sonic Electronix to meet or exceed the wattage ratings provided by the manufacturer. If this is marked as Yes, then you can trust the wattage ratings. If marked as No, then we have tested the amplifier and it did not meet the advertised wattage ratings. If marked as Not Tested, then the Sonic Electronix experts have not yet been able to test the amp.

Harley Davidson

September 17, 2013

I purchased two of these for my 2012 Ultra. I have one on top of the radio feeding the front speakers and one located in the trunk feeding the speakers in the lowers. I picked this model for the ability to be 2 ohm stable and produce 150 watts per channel. They do run hot and will need air around them. They blow away all the other amps I have used on bikes up to this point. Be prepared to piss off the cars around you even at 70. My friends tell me you can hear me very clear several blocks away. Running Polk MM 6 1/2 for speakers.

Impressed.

April 24, 2015

I have this amp bridged to run my 10" JL in a sealed box. I am impressed with the output of this amp for its size.

It's a straight forward install, easy to adjust gain and the cross over frequency.

I would highly recommend this to anyone who is thinking of using it for a sub amp. I just wanted something to round out the system in my wranger and easily fits the bill.

Just make sure to buy 10 gauge wiring (so you don't have to be like me and re-buy power/ground wire).

I Want to install in a 2012 Harley road glide with j&m 7.25 speakers and a tweeter pod. What do I need ?
David L on Oct 26, 2014
Best Answer: David,
I have installed two of these in a very small car and love them. One powers my component speakers and the second is driving my subwoofer. As long as your speakers can handle the power you would need the following
•A heavy gauge wire to power the amp. The shorter the wire the higher gauge wire you can use. I think a 6 or 8 gauge should work fine for your bike.
•Inline Fuse on the power wire to drive your amp. Some power wires come with a inline fuse. I would look for one and purchase it. It makes for a much cleaner install.
•Speaker wirer.
•A 18 to 22 gauge wire to run from your receiver to you amp to turn it on when the radio is on. I used 22 gauge for both of mine.
•RCA cables
•Some way to mount the amp. Homemade bracket?

Sonic cell sales Amp kits like:
Belva BAK82
InstallBay AK8
Belva BAK82BL (Blue)

Note: The Amp kits above are two channel left and right. If have four

I would hold off on a capacitor. You can always add one later if you get a lot of alternator humming/wining. I’m not using one and my system is fine without it.

Hopefully this helps.
