Key Benefits

• Four-channel car audio amplification.
• Separate 2-ohm and 4-ohm versions available in this listing.
• Listed 80Hz high-pass and low-pass filters.
• Compact enclosure measuring 13.6 × 22.8 × 5.5cm.

Power and Version Selection

The model is listed with a 2,000W RMS total rating. Actual output depends on the selected version, supply voltage, speaker load and test conditions. Confirm per-channel output and approved bridged configurations in the manufacturer's manual for the exact version before purchase or installation.

The selected option identifies a distinct amplifier version, not a switchable impedance setting. A version's impedance label must not be assumed to apply unchanged to bridged operation. Do not use a speaker load below the manufacturer's specified minimum for the configuration.

Professional Installation

Have a qualified installer verify speaker impedance and power handling, input compatibility, gain settings, electrical-system capacity, cable sizing, grounding, circuit protection and ventilation.

The existing listing references a 100A fuse for musical use. Treat this as a planning reference rather than a complete installation prescription, and confirm protection requirements for the exact version and installation.

Choose the SD2000.4 EVO 5 version that matches your speaker system, then configure your installation around its verified ratings.
