Deaf Bonce Apocalypse ASA-4000.1 | 4000 Watt Power Amplifier

Deaf Bonce Apocalypse ASA-4000.1 (Manual Apocalypse ASA-4000.1) is a single-channel Class D amplifier designed for subwoofer-focused car audio builds, delivering up to 4000 W RMS into 1 Ω from a 14.4 V supply.

• Class: D — a compact, high-efficiency design that concentrates power on the bass channel for demanding subwoofers.
• Number of channels: 1 — mono output optimized for a dedicated subwoofer setup.
• Frequency response: 10 - 250 Hz — concentrates amplification in the bass region while remaining capable of handling a broad low-frequency range.
• 1 Ohm RMS Power (14.4 V): 4000 W — maximum power rating at a 1 Ω load with a 14.4 V supply, signaling strong low-impedance performance.
• 1 Ohm RMS Power (12 V): 3010 W — power delivered into 1 Ω when the supply is 12 V.
• 2 Ohm RMS Power (14.4 V): 2620 W — higher than 4 Ω at the same voltage, suitable for low-impedance woofer loads.
• 4 Ohm RMS Power (14.4 V): 1530 W — reduced power at a higher impedance with the same supply.
• Minimum permissible load on the channel: 1 Ohm — ensures the amplifier is not driven below its safe operating impedance.
• Low pass filter: 35 - 250 Hz — allows you to tailor the upper limit of the bass signal reaching the woofer.
• Crossover: 12 dB/Oct — defines the slope of the filter, shaping attenuation beyond the cutoff.
• Subsonic filter: 10 - 50 Hz — helps remove very low frequencies that can burden the woofer or waste power.
• Bass frequency adjustment: 35 - 250 Hz — lets you dial in bass boost or attenuation within the stated range.
• Input terminal: 0 Ga — gauge of the input connection for signal drive.
• Output terminal: 8 Ga — gauge of the power/ground output, supporting high-current delivery.
• Working voltage: 9 - 15 V — compatible with typical automotive electrical systems and battery voltage variations.
• Signal-to-noise ratio: ≥ 92 dB — indicates a quiet hiss floor, preserving dynamic bass without excessive noise.
• Size (WxLxH): 26.6 x 9.4 x 2.5 inch — compact footprint suitable for tight installs in performance vehicles.

In a real-world build, this amp excels as the dedicated bass powerplant for a high-output subwoofer, delivering substantial low-end headroom into 1 Ω loads while offering filter and tuning controls to sculpt bass response precisely. The combination of a broad frequency range, robust current handling, and adjustable filters makes it well-suited for projects where space and raw bass power are priorities.
