Deaf Bonce Apocalypse ATOM-500.2 PRO | 500 Watt 2-channel amplifier

Deaf Bonce Apocalypse ATOM-500.2 PRO is a compact 2-channel Class D amplifier delivering 500W RMS per channel at 1 Ohm, with up to 1000W in bridge mode, all in a 7.7 x 5.5 x 2.1 inch chassis.

• 2-channel Class D amplifier: High efficiency switching design minimizes heat and power draw, helping a small-form-factor install stay cooler under heavy use.
• 1 Ohm RMS Power (14.4 V): 500W x 2: Maximum sustained power into a 1 Ohm load for demanding speaker pairs while maintaining control and clarity at high levels.
• 2 Ohm RMS Power (14.4 V): 390 W x 2: Robust output into moderate low-impedance loads with still-strong dynamic capability.
• 4 Ohm RMS Power (14.4 V): 231 W x 2: Efficient operation into higher-impedance speakers with ample headroom for everyday listening.
• 2 Ohm RMS Power (Bridge): 1000W x 1: Single-channel high-power operation ideal for sub or mono applications when a single amp is desired.
• 4 Ohm RMS Power (Bridge): 780 W x 1: Bridge-ready performance at a common car-subwoofer impedance option with substantial output.
• Minimum permissible load on the channel: 1 Ohm: Specifies the lowest stable impedance for stereo operation per channel.
• Minimum permissible load in a bridge connection: 2 Ohm: Indicates the lowest stable impedance when wiring in bridge mode.
• Low pass filter: 50-12000 Hz: Sets the upper frequency limit to focus bass or sub-bass by blocking higher frequencies from the amp output.
• High pass filter: 50-12000 Hz: Lets you attenuate sub-bass or low frequencies to protect speakers and balance overall sound.
• Crossover: 12 dB/Oct: Defines the slope of the filter roll-off, influencing how sharply frequencies are attenuated beyond the crossover point.
• Input terminal: 4 Ga: Indicates a thick, high-current input connection suitable for stable signal transfer.
• Output terminal: 10 Ga: High-current output wiring capability to support the amp’s power delivery in a car environment.
• Working voltage: 9 - 15V: Compatible with typical vehicle electrical systems, accommodating voltage variations in cars.
• Signal-to-noise ratio: 82 dB: Lower noise floor contributes to cleaner signal reception and reduced audible hiss at higher gains.
• Size (WxLxH): 7.7 x 5.5 x 2.1 inch: Compact footprint suitable for tight installs without sacrificing power capability.

The ATOM-500.2 PRO is well suited to stereo two-channel builds where space is at a premium or to bridge configurations for dedicated subwoofer or mono applications. Its 1 Ohm capability, bridge options, and versatile crossover controls allow precise frequency shaping while maintaining stable operation within a 9–15V automotive electrical environment.
