Deaf Bonce Apocalypse ATOM 5.5K PRO | 5500 Watt Power Amplifier

The Deaf Bonce Apocalypse ATOM 5.5K PRO is a 1-channel Class D monoblock amplifier designed for dedicated subwoofer bass with up to 5500 W RMS at 1 Ohm (14.4 V) for demanding installations.

• Class: D — high efficiency in a compact form, reducing heat generation for bass-heavy setups.
• Number of the channels: 1 — single‑channel design optimized for a subwoofer, simplifying wiring and tuning.
• RMS Power (1 Ohm, 14.4 V): 5500 W — maximum continuous power into a 1 Ω load, suitable for aggressive low-end response.
• RMS Power (1 Ohm, 12 V): 3900 W — power availability when vehicle voltage is around 12 V during operation.
• RMS Power (2 Ohm, 14.4 V): 2850 W — solid performance into a 2 Ω load, offering flexibility with subwoofer impedance.
• RMS Power (4 Ohm, 14.4 V): 1710 W — efficient operation into higher-impedance subs.
• Minimum permissible load on the channel: 1 Ohm — design expects loads no lower than 1 Ω for safe operation.
• Low pass filter: 40 - 250 Hz — selects bass content, helping to keep the amplifier focused on sub frequencies.
• Crossover: 12 dB/Oct — defines the slope of the filter, influencing how quickly frequencies roll off beyond the cutoff.
• Subsonic filter: 10 - 50 Hz — removes infrasonic content to protect drivers and tighten bass response.
• Bass frequency adjustment: 35 - 90 Hz — lets you tune the bass peak to match enclosure and sub characteristics.
• Input terminal: 0 Ga — high-current input connection for power delivery.
• Output terminal: 4 Ga — power/ground output connection sized for substantial current handling.
• Working voltage: 9 - 15 V — compatible with typical automotive electrical systems across operating conditions.
• Signal-to-noise ratio: 82 dB — indicates a low-noise floor for clearer bass in challenging installations.
• Size (WxLxH): 11.4 x 8.6 x 2.6 inch — compact footprint that fits in standard mounting spaces.

In a serious subwoofer build, ATOM 5.5K PRO provides a dedicated, high-current bass channel with flexible filtering and tuning options. It suits low-impedance subs at 1 Ω and supports customized bass shaping through its comprehensive filter suite, all within a compact, automotive-ready enclosure.
