    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.

    I installed a modest sound system in my ’04 Silverado Ext. cab. I wanted a system that would provide quality sound and at a satisfying volume. I wanted crisp highs and deep lows with a punch. I did my ‘homework’, learning about sound quality, and what to look for in quality sound products, read reviews (thank you for your reviews!), and shopped with Amazon. I replaced the factory cd/stereo with a quality double din receiver. I gladly bypassed the factory wiring harness (saving myself $80.00 and a lot of problems). I did use the speaker wires and radio ground wire from the harness and ran new power and remote wires. 8ft rca cables from the receiver to the amp. The amps front channel powers a set of infinity kappa 6.5″ door speakers rated at 220watts peak. The rear channel is bridged and powers a quality 10″ flat subwoofer rated at 800watts peak. The sound is amazing! If you take the time to learn what the amp settings are and how they are to be used. I have learned that ‘more’ isn’t always better. Low gain, for instance, is preferable to high. My front gain is set to about half-max. Freq. set to just passed half. If I had to guess, I’d say around a hundred hertz. The infinity’s get pretty low w/o distortion. I have the amp in 4 channel mode because of the sub, otherwise. The rear channel, bridged into 4 ohms puts out about 200 watts according to specs. The gain is only turned up a third, if that much, which is amazing because it’s kicking my ass. I had it higher at first but it was overpowering. The frequency is set just below a hundred hertz or just about where the front channel leaves off. It’s a beautiful blend. The punch-eq is set to close to half and provides plenty punch for me. It’s all working great together. I feel that I have more than enough volume. I have no distortion at tolerable volumes. The amp gets warm but not hot. I used 10 gauge power and ground wires. The ground is clean and solid. Mounted the amp on ‘the hump’ under the backseat next to sub. Plenty of clearance in this location. Well, I couldn’t be happier with my purchase. I hope my review will be of help to you. One more thing that I should mention. Each amp is rated I guess before shipment and my 400 watt amp actually rated at 525 watts. I believe I benefit from the extra wattage.

    *** A couple of weeks later… I love the sound of my system! This amp was a Great buy for me!

    This review is from: Rockford Fosgate R400-4D 400 Watt Full-Range Class-D 4-Channel Amplifier (Electronics)

    I hooked this up to a pair of Focal 165’s (60 watts RMS) on the front channels (no gain) and an old pair of Infinity Kappa 3-ways (111 watts RMS) on the rears (+2 gain I think). I was enjoying things on a 1-hr trip that first night, and halfway in, the rear speakers started cutting out. Even though I had read about this exact same problem in reviews on here or Sonic Electronix, I assumed it was the old Kappas’ fault. Today, I put a voltmeter to the channels to see if it was putting anything out to the rear. I cranked up the volume to instigate the problem, and lost my front/right Focal. So it’s not the speakers. I went to check onboard fuses, and the amp doesn’t even have any!

    I appreciate that Rockford wanted to cut corners to make this amp more affordable, but it looks like they went too cheap this time.

    ps- my build sheet said this amp put on 533 watts. Don’t be lured in by other people talking about how underrated these are because of the output pencilled in on their build sheet. When push came to shove, it’s still a shoddy amp.

    Edit 2/28/13: I replaced this unit with the Pioneer GM D8604-4, and it’s been solid. Better hardware, clear highs, good midbass, and no signs of fatigue for less money than the RF Prime.
