Small but powerful

Size matters in this industry and Rockford Fosgate's PBR300X4 has taken size to a whole new dimension. Its super small chassis design allows for the mounting of this amplifier practically anywhere inside a vehicle. Its size makes it perfect for those with limited space or for those who want to be heard but not seen. Its RMS power rating of 75 watts x 4 channels @ 4 ohms is guaranteed each and every single time by its CEA-2006 compliance. The use of MESHA3 and NOMAD technologies will keep this amplifier running at optimal performance while maintaining lower thermal levels and lower distortions levels. So whether you are limited on space or just looking for the next step in technology and products, the PBR300X4 is the perfect match for you.

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.
