Frequently Asked Questions - GZHA MINI ONE-K 24V Ground Zero
What type of vehicle can I use the GZHA MINI ONE-K 24V in?
It is designed for vehicles with a 24V electrical system, such as trucks, buses, boats, or heavy-duty equipment. Do not use in standard 12V cars without a voltage converter.
What is the power output of this receiver?
The receiver delivers 1 x 1000W RMS at 4 ohms and up to 2000W peak. It is a mono amplifier optimized for subwoofers.
Can I use this amplifier with a 12V battery?
No, it requires a 24V DC power supply. Using it with 12V will result in reduced power and possible damage. For 12V systems, consider a step-up converter or a different model.
How do I connect the GZHA MINI ONE-K 24V?
Connect the remote turn-on wire to a 12V+ signal from the head unit, RCA or high-level input to the audio source, and power/ground to 24V battery. Use a 4 AWG power cable and a fuse rated for the amplifier.
What speakers can I use with this amplifier?
It is a mono amplifier recommended for subwoofers with a nominal impedance of 2-8 ohms. Wire the subwoofer(s) to achieve a total load between 2 and 8 ohms for stable operation.
Does it include a low-pass crossover?
Yes, it has an adjustable low-pass filter from 50 Hz to 250 Hz, and a subsonic filter from 10 Hz to 50 Hz to protect the subwoofer from very low frequencies.
What are the dimensions and mounting options?
The amplifier measures 150 x 100 x 50 mm and weighs 1.2 kg. It can be mounted in any position, but ensure good airflow around the heatsink. Use the included screws to secure it.
How do I clean and maintain the amplifier?
Disconnect power first. Wipe the exterior with a soft, dry cloth. Do not use water, solvents, or abrasive cleaners. Check connections periodically for tightness.
What should I do if the amplifier goes into protection mode?
Protection mode can be triggered by overload, short circuit, overheating, or low voltage. Check all connections, speaker impedance, and ensure the power supply is stable. Let it cool down before restarting.
Where can I find spare parts or get repairs?
Contact an authorized Ground Zero dealer or service center. The amplifier has no user-serviceable parts inside. Do not open the chassis as it may void the warranty.
