Frequently Asked Questions - Doomsday ARU-3000/2 Deaf Bonce
What power wire gauge should I use for the ARU-3000/2?
Use at least 4 AWG power wire for optimal performance and safety, especially for long runs (over 4 meters). Use 0 gauge for maximum current capacity.
What is the minimum impedance per channel?
The amplifier is 2 Ohm stable in stereo mode and 4 Ohm stable in bridged mode. Using lower impedance may cause overheating or damage.
How do I adjust the gain on the amplifier?
Set the source unit to 75% volume, then slowly turn the gain knob clockwise until you hear distortion, then back off slightly. Use a multimeter for precise setting.
Can I use this in my home?
This amplifier is designed for 12V DC car systems. For home use, you need a high-current 12V power supply capable of delivering at least 100A. Not recommended without proper knowledge.
What does the 'Doomsday' series feature?
The Doomsday series offers high power output, durable construction, and advanced cooling. This model includes a 2-channel design with variable filters.
How do I bridge the amplifier?
Connect the positive speaker wire to the left channel positive terminal and negative speaker wire to the right channel negative terminal. Ensure impedance is 4 Ohms or higher.
What is the recommended fuse rating?
Use an inline fuse holder with a 200A ANL fuse on the main power wire near the battery for protection.
Why is my amplifier going into protect mode?
Common causes: low impedance (below 2 Ohms), short circuit in speaker wires, overheating, or low battery voltage (<11V). Check connections and ventilation.
Can I run a subwoofer with this amplifier?
Yes, you can bridge the two channels to drive a single subwoofer (4 Ohm load) or use one channel per sub (2 Ohm load). Set filter to low-pass for subwoofer.
How to clean the amplifier?
Disconnect power, then wipe the exterior with a dry microfiber cloth. Do not use any liquids or solvents. Keep ventilation slots free of dust.
