The PowerBass ASA3 600.4 is a compact, high-efficiency 4-channel car amplifier engineered for reliable, clean power delivery. Its MOSFET power supply and improved extruded chassis provide stable operation and enhanced heat dissipation for sustained listening sessions. Rated for 600W RMS total output, the ASA3 is 2-ohm stereo and 4-ohm mono stable to support a wide range of speaker and system configurations. Adjustable 12 dB/octave high- and low-pass electronic crossovers enable precise system tuning and seamless integration with factory or aftermarket head units. A variable bass boost and optional remote gain control give installers precise low-frequency control without altering mid and high fidelity. The chassis features a sporty illuminated PowerBass badge and a narrow footprint for flexible mounting in tight installations. Built-in overvoltage protection and broad input sensitivity improve system compatibility and long-term reliability. The amplifier’s combination of power density, thermal management, and tuning options makes it suitable for both performance-focused and OEM-retained audio upgrades. Technical design emphasizes low distortion and high SNR to preserve detail across demanding source material.
