Deaf Bonce Apocalypse ATOM 12.5K PRO | 12500 Watt Power Amplifier

The Deaf Bonce Apocalypse ATOM 12.5K PRO mono amplifier is built for extreme subwoofer duty, delivering 12,500 W RMS at 1 Ohm (14.4 V) to empower serious bass in high-performance builds.

• Model: ATOM 12.5K PRO — a dedicated high-power mono amplifier designed for peak subwoofer authority.
• Class: D — efficient switching design that maintains high output with controlled heat for sustained bass.
• Number of channels: 1 — single-channel output optimized for a dedicated subwoofer channel.
• Frequency response: 10 - 250 Hz — covers the core subwoofer range to reproduce deep bass and impact.
• 1 Ohm RMS Power (14.4 V): 12500 W — primary power rating for very low-impedance subs with ample headroom.
• 1 Ohm RMS Power (12 V): 10200 W — strong performance from a typical automotive 12 V system, preserving headroom during voltage dips.
• 2 Ohm RMS Power (14.4 V): 6950 W — alternative impedance option for matching different sub configurations.
• 4 Ohm RMS Power (14.4 V): 3870 W — additional impedance option for broader compatibility and efficiency.
• Minimum permissible load on the channel: 1 Ohm — supports very low-impedance subs common in high-power bass setups.
• Low pass filter: 40 - 250 Hz — restricts output to sub-bass frequencies, helping blend with enclosure tuning.
• Crossover: 12 dB/Oct —Defines the filter slope for a smooth transition into bass frequencies.
• Subsonic filter: 10 - 50 Hz — protects the woofer from ultra-low frequencies that can cause distortion or overexcursion.
• Bass frequency adjustment: 35 - 90 Hz — lets you tailor bass emphasis to your box design and listening preference.
• Input terminal: 0 Ga — built for heavy power routing to support high-current needs.
• Output terminal: 4 Ga — suitable for robust speaker connections from amp to subwoofer.
• Working voltage: 9 - 15 V — compatible with typical vehicle electrical systems and fluctuations.
• Signal-to-noise ratio: 85 dB — indicates a clean signal with a lower noise floor at high output levels.
• Size (WxLxH): 24 x 8.6 x 2.6 inch — defined footprint for planning installation space.

In a high-performance car audio install, ATOM 12.5K PRO serves as the dedicated bass power source for a single subwoofer or a focused low-frequency channel. Its 1 Ohm capability and substantial RMS power deliver headroom for loud, controlled bass, while the subsonic and bass-adjust controls help tailor the response to your enclosure and listening preferences. The 0 Ga input and 4 Ga output, combined with a 9–15 V operating range, support robust, reliable power delivery in typical vehicle environments.
