New Rockford Fosgate Prime 400 Watt Class D 4 channel Amplifier

Rockford Fosgate R400-4D 400 Watt Full-Range Class-D 4-Channel Amplifier Review

I have been a Rockford Fosgate customer for 20 years and this amp does not dissapoint. I have had several Punch amps over the years and currently have a Rockford Fosgate Power series mono amp running my RF Punch P3 12" sub. I was hesitant to try the Prime series amp to run my MB Quarts, but after trying it...WOW. Birth sheet says 544 watts RMS and its giving the Quarts all they can handle. Clean, clear, loud in classic Fosgate style. I had heard bad things about the Prime series, but my favorite installer assured me the quality issues have been worked out with this latest release. How many entry level amps are stable to 1ohm? Not many. Over the years I have been tempted by other manufactures products...JL, Pioneer, HiFonics,Memphis,Alpine....but I always return to Rockford Fosgate. Best amps and subs period. By the way I have been in the car audio game a long time...quality power trumps extra subs everytime for those looking for booming bass. In the 90's I had two 15" Punch subs in a sealed enclosure (250wrms)tied to a Punch 400 amp (200wrms @ 2ohms)and it hit...but now I have a Power 700 mono (700wrms) running one 12" P3 (600wrms @ 1ohm)in a properly sized vented enclosure and it hits harder. Rockford amps deliver the stated RMS wattage under worst case scenario conditions, competitors deliver their stated numbers under best case scenarios. With that said, I recommend this amp for running component sets. If you are looking for a sub amp, I would go with a Punch or Power series mono class D.
