Description
Deaf Bonce Apocalypse ATOM 3.5K PRO is a monoblock Class D amplifier that delivers 3500 W RMS at 1 Ohm from a 14.4 V supply, built for bass‑forward, single‑sub installations where every watt matters.
- Power output (1 Ohm, 14.4V): 3500 W RMS — high‑current performance ideal for demanding subwoofers in a bass‑heavy setup.
- Power output (1 Ohm, 12V): 2900 W RMS — maintains strong bass response in vehicles with lower charging voltage.
- Power output (2 Ohm, 14.4V): 2200 W RMS — solid performance when your sub is wired to 2 Ohms, balancing efficiency and output.
- Power output (4 Ohm, 14.4V): 1210 W RMS — suitable for higher‑impedance sub configurations with clean power delivery.
- Minimum permissible load: 1 Ohm — designed to drive aggressively low‑impedance subs without performance loss.
- Frequency response: 10–250 Hz — targets bass to low‑midbass region, leaving upper frequencies to the main speakers.
- Low pass filter: 80–20000 Hz — defines the upper cutoff for the sub signal, enabling precise bass control.
- Crossover: 12 dB/Oct — a gentler roll‑off that helps integrate the sub with other speakers.
- Subsonic filter: 10–80 Hz — protects the woofer from ultra‑low content that could cause flutter or strain.
- Bass frequency adjustment: 35–90 Hz — lets you tune the sub’s perceived depth and punch to the vehicle’s acoustics.
- Input terminal: 0 Ga — uses a 0 gauge power input for a low‑resistance connection.
- Output terminal: 4 Ga — speaker/sub output with a robust, high‑current path.
- Working voltage: 9–15 V — compatible with typical automotive electrical systems.
- Signal‑to‑noise ratio: 85 dB — contributes to clearer bass with minimal audible noise in‑car.
- Size (WxLxH): 10 x 8.6 x 2.6 inch — compact footprint that supports flexible mounting in various builds.
In a real car build, this amplifier excels as the dedicated subwoofer power module. The 1 Ohm stability and high output pair with a single, well‑matched sub to deliver loud, controlled bass, while the bass tuning controls and filters help integrate the woofer with the rest of the system. The 9–15 V operating range and robust power connections support a reliable, high‑current install with manageable heat and clean signal delivery.
