Frequently Asked Questions - ZEUS ZD-1950.1D Hifonics
What is the recommended impedance for the ZEUS ZD-1950.1D?
The amplifier is stable down to 1 ohm and works best with a final impedance load between 1 and 4 ohms.
What size fuse should I use?
A 100A ANL fuse is recommended and should be installed within 12 inches of the battery positive terminal.
How do I wire multiple subwoofers to this amplifier?
Wire subwoofers in parallel to lower impedance (e.g., two 2-ohm subs in parallel = 1 ohm) or in series to raise impedance, ensuring the total load stays within 1-4 ohms.
Can I use this amplifier with a factory stereo?
Yes, but you will need a line output converter (LOC) to convert the speaker-level signals to RCA low-level inputs.
What is the remote bass level knob for?
The included remote bass control allows you to adjust the bass boost level (0-18 dB) from the driver's seat without accessing the amplifier.
How can I prevent the amplifier from overheating?
Ensure the amplifier is mounted in a well-ventilated area, not enclosed, and the cooling fan (if equipped) is unobstructed. Also, match the impedance load correctly to avoid excessive current draw.
What power wire gauge is recommended?
Use 4 AWG or thicker power and ground wires for the full power capability. For shorter runs, 2 AWG is preferable to minimize voltage drop.
Does this amplifier have high-level (speaker) inputs?
No, the ZEUS ZD-1950.1D only has low-level RCA inputs. Use a line output converter if connecting to speaker wires.
How do I set the gain properly?
Use a digital multimeter or oscilloscope to set the gain without distortion. Alternatively, use the gain setting feature in the manual: turn the head unit to 75% volume, then adjust gain until the desired output is reached without clipping.
What is the warranty on the Hifonics ZEUS ZD-1950.1D?
It comes with a 2-year limited warranty covering defects in materials and workmanship. Register your product online to activate.
