Stetsom IR160.2 2-Channel Digital Amplifier

Stetsom IR160.2 is a 2-channel digital car amplifier delivering 80W RMS per channel into 2 ohms (160W total) and 45W per channel into 4 ohms, housed in a high‑performance aluminum chassis for rugged automotive use.

• Auto-turn On system: Provides Automatic Remote Trigger via audio connector, simplifying wiring and integration with head units.
• RMS Power at 2 Ohms: 2 x 80W RMS (Stereo) at 13.8V, giving substantial headroom for a small front-stage or sub-friendly setup.
• RMS Power at 4 Ohms: 2 x 45W RMS (Stereo) at 13.8V, suitable for efficient, moderate-power speaker pairing.
• Supply Voltage: 9–15V, compatible with standard automotive electrical systems.
• Frequency Response: 50 Hz – 23 kHz, covering deep bass through high treble for full-range musical reproduction.
• Signal-to-Noise Ratio: > 90 dB, indicating a low noise floor in normal listening levels.
• Total Harmonic Distortion: > 0.03% THD, preserving audio clarity with minimal coloration.
• Input Sensitivity: 2 V, defining how strong the source signal must be to reach full output.
• Input Impedance: 2.4 kΩ, presenting a compatible load to typical head-unit outputs.
• Minimum Output Impedance: 2 Ohms, enabling stable operation into low-impedance speaker loads.
• Current Consumption (Musical Signal): 6.4 A, reflecting modest heat and electrical demand under typical music playback.
• Current Consumption (Bass Signal): 12.8 A, illustrating higher draw when delivering bass-heavy content.
• Dimensions: 29 x 58 x 77 mm (H x W x D), compact enough for tight installations.
• Weight: 0.15 kg, contributing to flexible mounting options in vehicles.
• FM Interference: Does not interfere with FM; keep speaker cables away from the radio antenna and ground internal antennas to chassis if used.
• Safety Energy technology: Provides very high efficiency and low consumption, supporting cooler operation and reduced battery load.
• Aluminum construction: High-performance aluminum housing delivers robust durability in automotive environments.

In a real car audio build, the IR160.2 is well-suited for a compact two-channel front-stage or a small sub-friendly configuration, offering solid power, clean output, and installation-friendly features like auto-turn on and efficient operation. Its low noise, wide bandwidth, and stable 2-ohm capability help you achieve clear, dynamic sound without excessive heat or wiring complexity.
