I stepped up to the Power 400 from running a Prime series and all I can say is WOW! I don't know what RF does differently with these, but the difference is worth the coin. Used in conjunction with the PEQ remote you can have a little pop or a huge boom on demand. Even when pushing my 2 subs for about an hour, there is no sign of excessive heat. From the complete adjustability on each channel, to the fact that this amp is actually putting out almost 500 watts really sets this heads and shoulders above the rest of the pack in this price range. If your power needs are near what this amp provides, you owe it to yourself to give it a shot. I honestly could not be more pleased.



Thanks Rockford Fosgate and SonicElectronix!

This amp pumps out the power, and then some. I have it on my front mids and highs... and its sends more power to them than they ever will need.



Exactly what I would expect from a Rockford Product.

I bought this amp to replace a JL. This thing is amazing. The gain is a very nice addition and works like a charm. Tunes very easily and delivers crisp sound to my Boston Acoustics component 6.5s. I have it placed between a bench and a sub box (very little air circulation) and this thing stays cool even on road trips. Very good buy.
