Product Overview
Run your front speakers, rear speakers, and subwoofer from one compact car audio amplifier with the Rockford Fosgate Prime R2-750X5 5-channel amplifier. Its Class-D design delivers 750 watts total, with adjustable crossovers, individual input gain controls, and factory-signal inputs for flexible system setup.
Use the R2-750X5 in a factory or aftermarket build when you want five channels of amplification in a single chassis. The top-mounted controls keep adjustments accessible during installation and tuning.
Key Features & Benefits
- Five-channel output: Power front, rear, and subwoofer channels from one amplifier.
- Factory-signal inputs: High-level inputs accept factory signals, while RCA pass-through outputs let you branch signals to additional gear.
- Flexible input selection: Choose 2-, 4-, or 5-channel input routing to suit the system signal layout.
- Separate gain controls: Adjust front, rear, and sub input levels independently for a balanced system.
- Tunable sound: Variable infrasonic filtering, adjustable Butterworth crossovers, and onboard Punch EQ help shape the system’s response.
- Accessible, protected operation: Top-mounted controls simplify adjustments, while short-circuit, over-current, and rollback protection support safe operation.
