Rockford Fosgate Prime 1,200-Watt Class-D 1-Channel Amplifier

Are you looking to wake the whole damn neighborhood up? Do you absolutley positively have to let your friends know you are there from three blocks away? This is the amp for you. It aint called the prime for nothing. This amp will turn your car into a giant vibrator and boy is it relaxing. If you are relaxed by being punched in the face. Because thats what this will do.itll tender you up like a slab of steak with a never ending barrage of bone jarring bass. The guy in the car next to you will probably tip you for the gentle massage he got.

I’ve been a big fan of Rockford Fosgate amps since the late 80’s when my brother had six subs all powered by a single Punch 150. These amps have always delivered more than rated and Rockford has been ahead of almost every other manufacturer in terms of technology and engineering. This amp is the most powerful of the “Prime” series, their budged line (called Series 1 back in the day) rated to deliver 1200 watts into a 1 ohm load. Other ratings include:

400 watts RMS into 4 ohms
800 watts RMS into 2 ohms
1200 watts RMS into 1 ohm

I have an SMD/D’Amore Engineering Amplifier Dyno AD-1, so I’m able to test and confirm or deny a manufacturers ratings. Although many car audio manufacturers fudge their wattage numbers, companies such as Rockford Fosgate and JL Audio never fail to meet their ratings. Here’s what I measured (all taken at 40Hz, wheres many mfg’s test at 100Hz, which is not as demanding on the amp):

473w @ 14.42VDC 4 ohms, certified to 1% THD
484w @ 14.4VDC 4 ohms, uncertified to clipping
486 @ 14.34VDC 4 ohms, Dynamic RMS Power

822w @14.3VDC 2 ohms, certified to 1% THD
864w @14.3VDC 2 ohms, uncertified to clipping
891w @14.38VDC 2 ohms, Dynamic RMS Power

1381w @14.23VDC 1 ohm, certified to 1% THD
1392w @14.11VDC 1 ohm, uncertified to clipping
1532w @14.2VDC 1 ohm, Dynamic RMS Power

As you can see, the amp surpassed each and every rating, even providing less input voltage and a lower test frequency. The birthsheet included stated 1318w at 1 ohm, 14.4VDC, but did not specify the test frequency. We were spot on this measurement.

My amp came in at 1235 watts. I’ve hooked it up to four p2d2-8s at 1ohm and holy sh*t, they pound. No complaints whatsoever. New ride, new custom box. Need to fine tune but already smiling.

My amp birth sheet came saying about 1300 watts in reality, and I do not doubt it at all. Classic Rockford quality, even on their lower end stuff. This amp puts all of its power out 100% cleanly to my two P3D4 15’s.

This is the best monoblock amp I’ve ever owned. I was a little worried about buying the Prime model, but I’m totally blown away. I replaced an NVX 1200w amp and I’m so glad I did. I have 2 Sundown Audio SA 8 V 3’s 2 ohm, and this amp rocks them. This amp is rated 800rms at 2ohm, and I barely have this amp turned up. I have the gain set at 3 and the power set a little more than 1/3rd. The clarity of the bass and the deepness of the notes are amazing! I’ve had tons of systems over the years, and this amp is the best. I have this amp paired with a Rockford Punch for my JL 3 C’s door speakers. I’m getting a 2nd battery this weekend to give it some extra juice and keep the headlights from flickering.

Pro’s-amazing sound, crazy amount of power, clarity
Con’s if any-gets a little hot and no clipping sensor

I purchased this amp with the intent of getting the punch series instead but was a bit short on cash, however this amp made me think otherwise once it was all hooked up. Out the box its got a really small footprint and has a decent amount of weight to it. I also bought the knuconcepts 4gauge wiring kit along with it and it delivers all the power this amp will need. Its currently powering 2 RF P3 12s with the 2ohm dvc and i have both wired at 2 ohms. This amp has no problem with making these subs move air. Ive had the volume on the head unit up loud without even the slightest hint of distortion. It just delivers extremely poweful and clean bass. The auxiliary bass remote is also very nice and the dial has a notch type of feel to it as opposed to a dial that just slides, you can accurately dial in the amount of gain you want by feeling for the clicks when you turn it. Overall, for this series of rockford amps being the lowest of the group, the prime 1200w delivers power you wouldnt expect from its size. Definitely impressed with the performance and quality of this amp.

awesome amps, have it powering 4 – 10’s and I still haven’t been able to turn it all the way up because its just too loud. Would buy two if I my alternator could take it

Perfect for 2 2ohm P3’s in a tuned box
