Verdict
As an avid music listener, I like that this amplifier delivers plenty of power and control options. And it’s versatile enough to be hooked up to most car audio systems. That said, I don’t recommend it for someone looking to enhance their factory system without first making other upgrades. But paired with quality speakers and a subwoofer, it has what it takes to upgrade that epic road trip playlist to the next level.
Pros
- Simplified set-up process (C.L.E.A.N. technology)
- Highest efficiency class (Class D)
- CEA-2006 Compliant
Cons
- Sound not as high-fidelity as Class A or AB
- Wiring, fuse required but not included
The Rockford Fosgate R2-750X5 Prime is a 5-channel amplifier. It’s bridgeable, so I have the option to hook it up only to my front speakers, instead of all four.
At 2 ohms, I can get 100 watts for each of my four speakers, or 200 watts for each of my two front speakers when bridged. Either way, the R2-750X5 Prime drives a subwoofer with an impressive 350 watts.
This is a Class D amplifier, which benefits from being the most efficient and most compact class. However, Class AB amplifiers are capable of producing somewhat higher-fidelity sound. I would argue that for car audio, the benefits of having a lightweight, efficient, cool-running amplifier outweigh any of the subtle deficiencies in sound fidelity. But if you’re a staunch audiophile, you might disagree.
Installation and setup can take a lot of time and equipment. So I appreciate Rockford Fosgate’s C.L.E.A.N. technology. It makes setting up the system to optimal levels significantly easier.
All in all, if you have the audio system to match its power, this is a great amplifier to consider. And it’s pretty nice on the eyes too.
