300W RMS Punch Series Boosted Rail Compact 4-Channel Amplifier
Product highlights
• RMS 75 x 1 @ 4 ohm
• Features Rockford Fosgate's Class-BR Topology
• CEA-2006 Compliant
• Ultra Compact Chassis
• Boosted Rail Design
• Dimensions: 6.75"L x 4.25"W x 1.53"H
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 PBR300X4 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.
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.
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.

Great Amp!
I just finished installing one of these amps in an '89 Porshe Carrera...wow! I still am in disbelief how this tiny amp pushed 2 sets of JBL components.. This car screamed and my customer was extremely happy with his purchase. I have been installing for over 14 years professionally and still can't believe this little amp did what it did..10 gauge wire is recommended but I managed to install it with 8 gauge... I could see the amp running hot if the wire run is long using 10 gauge. For future purchasers, buy 8 gauge wire if your run is longer than 10 ft.

The amp made my speakers (Prime6x8) sound like they were top of the line. i had this amp hooked up for about 14 days until all of a sudden no sound would come through my speakers anymore just a buzzing noise the amp would turn on but no sound all cables were fine.

I installed this into my motorcyle fairing pushing 4 - 51/4. What a difference. Now I can hear it over my loud pipes!

Amp has a really small footprint. The amp I have is putting out 87 watts per channel making for a total of 348 watts. I don't need the gain turned up past 3 in order to make my ears ring. I have it hooked up to two Pioneer 4x6 speakers and two Pioneer 6x9 speakers and it rocks them all day and all night.
I had my entire stereo professionally installed and I don't have any problems with it.

I was very unsure whether or not to get this amplifier based on the mixed reviews but I did anyway. It has now been 6 months and not a moments trouble. To tell you the truth the size and sound reminds me of the old punch 75 amps. Great sound from a small package. I would definitely not hesitate to purchase this again.

This little amp in combination with a good set of speakers is well worth the money. I mounted it in my fairing of my motorcycle. It easily powers two six inch rounds up front, and two 6x9's in the bags. It sounds great without any distortion. Installation was simple and quick. I would definitely recommend this amp.

Good amp for bikes just can't turn it up all the way hurts my ears.
High distortion but that it due to the Harley deck that has .5thd where I'm used to like .001 THD. I am sure if Harley made a radio with low inputs it would be cleaner sound. All that said I would buy this amp again for any bike hi or low inputs as I always been fond of Fosgate

I got this for my husband for the holidays. It is small and compact and can be easily hidden within the vehicle. It can get a little warm but he has not expierenced any issues, if you are worried you can always mount it near/ with a cooling fan. He is very pleased with this little amp. It packs a punch.
