The Rockford Fosgate R2-750X1 is built for people who want real, dependable bass power without guessing games. It is CEA-2006 certified, meaning you get verified 250W RMS at 4 ohms with accurate performance ratings you can actually trust when comparing amps. From there, it steps up hard with 500W RMS at 2 ohms and up to 750W RMS at 1 ohm, giving you the flexibility to match different subwoofer setups while still getting strong, controlled output.
This amp gives you full control over how your bass feels and hits. The adjustable infrasonic filter lets you fine-tune between 15 Hz and 40 Hz to protect your subs from damaging ultra-low frequencies, while the built-in low-pass crossover adjusts from 50 Hz to 250 Hz so you can lock in the perfect cutoff. On top of that, the Punch EQ bass boost gives you up to +18 dB at 45 Hz, so when you want that extra kick, it is right there on demand without needing extra gear.


The R2-750X1 is designed to make setup smooth and flexible. It supports vertical, horizontal, or inverted mounting, with best cooling performance when installed horizontally. The auto signal turn-on feature makes installation easier by powering on automatically with speaker-level input, so you may not even need a remote turn-on wire in some builds. You also get a wired bass level remote for quick adjustments from the driver’s seat, plus heavy duty 4-gauge power and 8-gauge speaker terminals for solid connections. With nickel plated RCA inputs and pass-through outputs, expanding your system later is clean and simple without redoing your entire setup.

Bought for my 2 ohm 300 Watt sub and the pair is delivering positive results. So compact for a 750 Watt sub and the knobs are very responsive. Love the CLEAN technology. The lows are really cleaner compared to my older setup.
Amp is one of the best ones on the market
Awesome product! More power than it's rated. Get one Rockford never disappoints. This amp is a beast!
