R2-750X5

The Rockford Fosgate R2-750X5 from the PRIME R2 series is a powerful and efficient 5-channel Class-D amplifier that combines four speaker channels and a separate subwoofer channel in a compact enclosure. This makes the amplifier ideal for building a complete car audio system with front and rear speakers, as well as an additional subwoofer.

Thanks to modern Class D technology, the R2-750X5 offers high energy efficiency with low heat generation. The integrated C.L.E.A.N. technology makes it easy to precisely adjust the input gain and helps prevent distortion caused by incorrect level settings. The variable crossovers allow the speaker channels and the subwoofer to be optimally matched to each other.

In addition, the amplifier features balanced differential inputs, high-level inputs with an automatic power-on function, and a switchable input configuration for 2-, 4-, or 5-channel operation. The built-in Punch EQ allows for custom tuning of the bass range, while the solid aluminum heat sink ensures reliable heat dissipation.
