Clean Power You Can Actually Trust

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.

Dialed-In Control for Serious Bass Tuning

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.

Easy Installation With Real-World Flexibility

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.
