Infinity Reference 6001A 600 Watt Monoblock Amplifier

The Infinity Reference 6001A delivers 600W RMS at 2 ohms in a compact mono subwoofer amplifier, built for bass-heavy installs where space and electrical load matter. Its Class D design keeps heat low while preserving efficiency, and a wired remote bass control lets you dial in output from the driver’s seat.

• Power output: 350W RMS x1 @ 4 ohms; 600W RMS x1 @ 2 ohms — provides solid bass headroom for a single sub when running at a low impedance.
• Class D design: high efficiency with reduced heat in the trunk, enabling compact installations without compromising output.
• Variable low-pass filter: 32–320 Hz, 12 dB/oct — lets you set the Sub’s cutoff to match enclosure tuning and listening preferences.
• Variable bass boost: 0–12 dB @ 45 Hz — adds controlled bass emphasis at the sub’s fundamental region for deeper impact.
• Phase switch: 0° / 180° — aligns the sub’s timing with the rest of the system for coherent bass integration.
• Inputs: Preamp and speaker-level inputs with signal-sensing turn-on; bare wire-to-RCA adapters included — supports factory or aftermarket radios and easy high-level connections.
• Remote bass control: wired remote included with 16.5' cable — adjust bass level from the driver’s seat for on-the-fly tuning.
• Dimensions and warranty: 8-5/8"W x 2-1/4"H x 7"D; 1-year warranty — compact footprint fits tight installs while offering supported coverage.

In real-world builds, the 6001A powers a single sub with reliable thermal performance and flexible tuning. It integrates with both factory and aftermarket systems via scalable inputs, while the wired remote provides hands-on control away from the trunk. The package includes four 30A fuses (two installed / two spares) and mounting hardware, making the upgrade straightforward and install-ready.
