Frequently Asked Questions - ZEUS ZD-1350.1D Hifonics
What impedance can I run the ZEUS ZD-1350.1D at?
This amplifier is stable down to 1 ohm, delivering 1350W RMS. It can also operate at 2 ohms (750W) and 4 ohms (450W).
What is the recommended power wire gauge?
For full power, use a 4 AWG power and ground wire. For lower power, 8 AWG may suffice, but 4 AWG is safer.
Does the amplifier include a remote subwoofer level control?
Yes, the ZEUS ZD-1350.1D comes with a wired remote level control for convenient bass adjustment from the driver's seat.
What type of fuse does the amplifier require?
It uses two 30A maxi blade fuses. Always replace with the same rating to avoid damage.
Can I bridge this amplifier?
No, this is a monoblock amplifier designed for a single subwoofer or multiple subs wired in parallel. It cannot be bridged with another amplifier.
What is the subsonic filter for?
The subsonic filter blocks frequencies below its set point (10-50 Hz) to protect your subwoofer from damaging infrasonic signals, especially in ported enclosures.
How do I adjust the gain?
Set the gain using a multimeter or oscilloscope. Start with gain at minimum, play a test tone at 50 Hz, and adjust until you reach the desired voltage (e.g., for 1350W at 1 ohm, target ~36.7V RMS).
Is the amplifier fan noisy?
The fan is temperature-controlled and generally quiet at low speeds. It may ramp up under heavy load but remains acceptable for most users.
What is the recommended minimum load?
The minimum load is 1 ohm. Going below can trigger protection or damage the amplifier.
Does the amplifier have speaker level inputs?
No, it only accepts low-level RCA inputs. If your head unit lacks RCA outputs, use a line output converter (LOC).
