Infinity Reference 7005A 5-Channel Amplifier

Infinity Reference 7005A is a compact 5-channel amplifier designed to power a complete car audio system from a single unit, delivering 50W RMS x4 to the front/rear channels and up to 500W RMS to a dedicated subwoofer channel. Bridge the front channels to 3-channel mode for 150W RMS per side, ideal for a high-performance component setup paired with a powered sub.

• 5-channel car amplifier: Combines four full-range channels with a dedicated sub channel to simplify wiring and maximize system ambition in a single chassis.
• 4-ohm power: 50W RMS x4 + 320W RMS x1: Adequate mid/high power for standard component and coaxial speakers while providing strong sub power on the same unit.
• 2-ohm power: 75W RMS x4 + 500W RMS x1: Lower impedance load yields higher output, useful for demanding front speakers and a robust sub channel when compatible with your speakers.
• Bridged rear/front: 150W RMS x2 @ 4 ohms + 500W RMS x1 @ 2 ohms: Bridge option enables higher single-channel power for a high-performance front stage combined with a powered sub.
• Hybrid design: Class AB (front/rear) + Class D (sub): Front and rear channels prioritize clarity, while the sub uses efficient switching to minimize heat and electrical draw.
• Independent crossovers: Front/rear channels use high- and low-pass filters (32–320 Hz, 12 dB/oct) for precise channel-by-channel tuning.
• Subchannel features: Low-pass filter, bass boost (0–12 dB at 45 Hz), and phase switch (0/180°) to dial in low-end response with your enclosure and vehicle.
• Inputs and install flexibility: Preamp and speaker-level inputs with signal-sensing turn-on; bare wire-to-RCA adapters included for high-level connections.
• Wired remote bass control included: Adjust bass from the driver’s seat for on-the-fly tailoring of the sub output.
• Power wiring and protection: Recommended power/ground wire: 4-gauge; Fuse rating: 30A x3; six 30A fuses (3 installed / 3 spares) included.
• Dimensions: 14-3/16"W x 2-3/16"H x 7-1/8"D.
• Warranty: 1 year.
• What’s in the box: 5-channel amplifier; Six 30A fuses (3 installed / 3 spares); 4 speaker wire-to-RCA adapters; Wired remote bass control with 16.5' cable; Mounting hardware; Logo badge; Owner's manual.

The setup-oriented design supports factory or aftermarket head units, with signal-sensing turn-on and flexible input options. Independent channel tuning and a dedicated sub channel help you achieve precise tonal balance, while the compact footprint and included mounting hardware simplify integration in trunks or under-seat locations.
