Rockford Fosgate Ultra small amps

bigaudiofanat · 11-19-2011, 05:34 PM

I got my hands on one of these babies earlier today. They are SMALL the PBR300X1 is about the size of two smart phones side by side. Each one is one channel but ultra efficient at making its power using new Boosted Rail Technology. They hardly warm up and can power speakers or subs. They would easily fit into the foam piece in the trunk or make something custom. They require very little power to run. You can run them off a 12 gauge power wire if you choose but I would recommend a run of 8 gauge and run a distribution block.

Besides these Fosgate amps, what are some other mini amps that offer decent quality? I currently have massive audio amps and may be looking to make a switch....

cptspeed · 11-21-2011, 05:34 PM

Are you recommending these.

Rafa341 · 11-21-2011, 05:54 PM

Just ordered 2 I'll post pic of install later

They are the only ones I know of right now that are using this technology. I am doing a install in cali with a set of these and another one is going in a dodge ram.

Will let you know what I think of them.

They will be the only ones with the technology, RF has a Patent Pending on it.

Astrosfan · 11-26-2011, 02:09 PM

sub'd... seems like a good amp to run a 8 or 10

eastwest2300 · 11-26-2011, 05:17 PM

Hey Matt let me know how these turn out.

bigaudiofanat · 11-26-2011, 09:41 PM

Found out something about these, they are made to only run subs they can not reproduce the frequencies that are need to run speakers.

ahhhhh... wow, that changes up the game just a bit.

The PBR300X4 (Which is the 75x4 version) is a full range amp which can run mids and highs just fine as it is more like a Class-AB amplifier.

They are sought after much like the Elf/Arc Mini amps in the motorcycling world.
