PBR300X1- 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 PBR300X1 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 - 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 - 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 - 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.

It's so small and powerful!

Okay, so get over the "That's what she said"-ish title, this amp fears no man! It is the size of my palm for crying out loud! The RF PBR300X1 is a fantastic amp for your system. Being that it is 1 ohm stable producing 300 watts RMS (my amp birthing sheet gave it a 327 RMS!), it matches the RF P3S-1X12 or P3S-1X10 to a tee! Being that I opted for the 12, I am more than satisfied. Do yourself a favor and get the RF PEQ bass knob and true 10 AWG OFC wire (like the Kicker DPK10, idea?) to power this little war-horse. So, what are you waiting for? PUT IT IN THE CART!

Great for powering small factory subs

Ran it in an 2010 Honda Ridgeline. Replaced factory radio with double din and installed the amp behind the stereo. Powers factory sub great. An easy fix/upgrade when needing to run factory sub with aftermarket radio.

This little amp is a beast!

I have this hooked up to an RE Audio SRi 10" in a 1.5ft3 probox and this thing slams. You can hear it down the street. Birth sheet said 94 watts at 4ohms, 175 watts at 2ohms, 304 watts at 1ohm, and a max of 911 watts. I recommend getting the PEQ remote because there are no adjustments of the +18db punch eq other than from the optional remote. I can't wait for the release of the PBR300X4 to hook up my highs, just ordered a new set of power RF T1652 to go with my 525s.

Little Giant Amp

I use Rockford Fosgate PBR300X1 for drive sub woofer box. It's very compact with high power. Enough for drive bass power. It's a good choice.

This amp rocks

I really like this amp alot. I have two of these in my car running two 2011 P3 12s. (One to each sub wired at 1ohm). These slam! I custom built a box to spec for the subs and no-one believes me that they are taking only 300 watts RMS each. People cant believe the power these little guys can push. They sound great and can fit in tight spaces. You would almost have to hear it to believe it, they did SO much better than I had expected. I also paired these with a PEQx3 and are run through a 360.2.

Rockford Fosgate Punch PBR300x1

I was planning on using only one Rockford punch amp in my Saturn Sky project. But after hooking everything up in the basement and seeing how well the Punch PBR 300x1 drove my sub-woofer. I decided to replace the new Kenwood amp I purchase with a second RockFord Punch PBR 300x2. I couldn't believe the difference this amp made on my door speakers. I would high recommend these amps, especially if you have minimal installation space.

Small Package Amp that Rocks

This amplifier has been fantastic. So much clean POWER from such a small package. Easy to mount, easy to hide, it's just a great piece of audio engineering. I would HIGHLY recommend this amplifier to anyone in need of a very solid amp, in a very small package.

Punch!

These little amps are fantastic! This is the first mono version 300x1. Running 2 10s in parallel for 2 ohm loaf. Amp only gets warm to the touch when run hard. So small it will hide in small spaces for a stealth installation. Also the PLC2 makes this amp even better, easy thump control for changing music.

good amp for hybrid

Used in 2010 Prius. Seems to have plenty of power for the subwoofer, and does not draw much power at all. I really like that all the connections are removable. Great price on sale!
