Description
The Deaf Bonce Apocalypse ATOM 9.5K PRO is a 1-channel Class D mono amplifier built for extreme bass in demanding car audio installs, delivering up to 9500 W RMS at 1 Ohm from a 14.4 V supply.
- 1‑Channel Mono Class D: A single high‑current output channel optimized for tight, high‑power bass performance while keeping heat and size in check.
- Power output (1 Ohm, 14.4 V): 9500 W RMS — maximum capability at a 1 Ohm load, indicating strong low‑impedance bass headroom when the vehicle supply is near 14.4 V.
- Power output (1 Ohm, 12 V): 8050 W RMS — shows substantial capability even when the electrical system operates around 12 V.
- Power output (2 Ohm, 14.4 V): 5650 W RMS — a significant rating for higher impedance loads while preserving bass authority.
- Power output (4 Ohm, 14.4 V): 3420 W RMS — solid performance into a 4 Ω load with stable regulation.
- Minimum permissible load: 1 Ohm — the amplifier is designed to operate at 1 Ohm, enabling aggressive subwoofer wiring options.
- Frequency response: 10 – 250 Hz — covers deep bass through to upper sub ranges, shaping the overall bass character.
- Low pass filter: 40 – 250 Hz, 12 dB/Oct — sets the subwoofer bandwidth and helps keep the signal focused on bass frequencies.
- Subsonic filter: 10 – 50 Hz — removes inaudible ultra‑low content to protect the sub and improve efficiency.
- Bass frequency adjustment: 35 – 90 Hz — lets you tailor the bass emphasis to vehicle acoustics and personal taste.
- Input terminal: 0 Ga — indicates a heavy‑gauge input connection designed for high current.
- Output terminal: 4 Ga — heavy‑gauge speaker output wiring suitable for demanding subloads.
- Working voltage: 9 – 15 V — aligned with typical automotive electrical systems, allowing operation across common vehicle voltages.
- Signal‑to‑noise ratio: 85 dB — suggests low intrinsic noise relative to rated output.
- Size (WxLxH): 20.8 x 8.6 x 2.6 inch — compact footprint for versatile mounting in a variety of car installations.
Benefits: This amp targets a dedicated subwoofer channel or a small multi‑sub setup, providing extreme headroom at 1 Ohm while offering precise tonal control via LPF, Subsonic, and Bass Adjustment. The automotive‑ready 9–15 V range and heavy‑gauge input/output terminals support demanding, high‑current bass presentations, with a clear path for clean, controlled, high‑volume low end in a performance‑oriented install.
