Deaf Bonce Apocalypse ASA 550.4 4 Channel Full Range Amplifier

The Deaf Bonce Apocalypse Sport ASA-550.4 is a 4-channel, full-range Class D amplifier delivering 550W per channel at 1 ohm, built for demanding car audio builds that demand clean, dynamic power and precise control.

• 4-channel Class D design: High efficiency and compact heat management for tight installations in modern vehicles.
• RMS power (14.4 V): 1 Ohm: 550W x 4; 2 Ohm: 350W x 4; 4 Ohm: 225W x 4 — provides scalable performance for different speaker loads and system goals.
• Bridge mode: 2 Ohm: 1100W x 2; 4 Ohm: 700W x 2 — two channels can be bridged to power a sub or high-power speaker pair with increased output.
• Minimum permissible load: Channel: 1 Ohm; Bridge: 2 Ohm — defines the safe operating limits to maintain reliable performance.
• Frequency response: 10–20000 Hz — covers the full audible range for accurate reproduction of music, from deep bass to smooth treble.
• Filters and crossover: Low Pass 50-1200 / 500-12000 Hz; High Pass 10-1200 / 100-12000 Hz; Crossover: 12 dB/Oct — flexible per-speaker tuning to match subwoofers, midranges, and tweeters.
• Terminals: Input: 0 Ga; Output: 8 Ga — specifies wiring gauges for power/ground and speaker connections in typical installations.
• Working voltage: 9–16V — automotive-friendly operation accommodating vehicle electrical conditions.
• Signal-to-noise ratio: ≥ 90 dB — low noise floor helps preserve detail and dynamics in loud listening scenarios.
• Dimensions: 16.93 x 9.45 x 2.5 inches — a relatively compact footprint for a high-power 4-channel amp.

In a real car audio build, the ASA-550.4 serves as a versatile backbone for a multi-amp setup or bridged sub-systems. Its broad frequency range, adjustable crossover options, and solid SNR deliver clean, controlled sound across front and rear channels or when pairing two channels for higher-subwoofer output, all within automotive electrical limits.
