Deaf Bonce Apocalypse ATOM 1300 PRO | 1300 Watt Power Amplifier

The Deaf Bonce Apocalypse ATOM 1300 PRO is a single-channel Class D monoblock amplifier delivering 1300 W RMS at 1 Ohm from a compact 7 x 5.5 x 2.1 inch chassis, built for serious bass in demanding installs.

• Channel configuration: 1-channel monoblock design optimized to drive a single subwoofer with high current for deep, controlled bass.
• Power output (1 Ohm, 14.4 V): 1300 W RMS — ensures strong bass capability when wiring a low-impedance sub, provided the sub and enclosure are matched to the amp.
• Power output (1 Ohm, 12 V): 1020 W RMS — maintains substantial bass headroom even as vehicle voltage fluctuates toward the lower end of its range.
• Power output (2 Ohm, 14.4 V): 780 W RMS — useful when pairing with higher-impedance subs while preserving significant bass output.
• Power output (4 Ohm, 14.4 V): 520 W RMS — solid performance with standard 4-ohm subs in typical installations.
• Minimum load on the channel: 1 Ohm — the amplifier is stable down to a 1 Ohm load, enabling aggressive subwoofer configurations.
• Low pass filter: 40 - 250 Hz — shapes the amp’s output to surround the subwoofer’s natural range, reducing unwanted high-frequency content.
• Crossover: 12 dB/Oct — a second-order slope that provides efficient attenuation of frequencies outside the target bass band.
• Subsonic filter: 10 - 50 Hz — protects subwoofers from excessive excursion by rolling off ultra-low frequencies.
• Bass frequency adjustment: 35 - 90 Hz — lets you fine-tune the perceived bass emphasis to match the vehicle and speaker setup.
• Input terminal: 4 Ga — high-current input support for stable signal transfer from head units or preamps.
• Output terminal: 10 Ga — provides ample current capability to the subwoofer with minimal voltage drop.
• Working voltage: 9 - 15 V — compatible with typical automotive electrical systems and alternator charges.
• Signal-to-noise ratio: 93 dB — indicates low noise floor for cleaner bass output.
• Size (WxLxH): 7 x 5.5 x 2.1 inch — compact footprint that fits in tight spaces alongside other amps.

In a real-world build, the ATOM 1300 PRO serves as the dedicated subwoofer channel in a high-power system, with enough headroom to drive demanding low-impedance subs. Its 1 Ohm capability, adjustable low-pass and subsonic filtering, and bass tuning controls give precise, integrated bass response while maintaining a clean signal thanks to a high 93 dB SNR. The combination of heavy-gauge wiring connections and a compact chassis makes it a practical choice for tight installations where space and current headroom matter.
