Frequently Asked Questions - GZIA 2080HPX Ground Zero

How do I connect the amplifier to an OEM headunit?

Use the High Level Input (speaker level) on the amplifier. Connect the speaker outputs of your headunit to the HI INPUT terminals. The amplifier will automatically turn on when a signal is detected (Auto-On function). Do not use the remote terminal in this mode.

What is the recommended fuse rating for the GZIA 2080HPX?

The recommended fuse rating is 20 A. Use only a fuse identical to the supplied one. Using a different rating may cause damage.

Can I use both high level and RCA inputs at the same time?

No, you must use either the High Level inputs or the Cinch (RCA) inputs. Using both simultaneously can damage the amplifier.

Why is the protection LED on?

The protection LED indicates an error. Common causes: short circuit on speaker wires, overheating (the amplifier will shut down temporarily), or overload. Check speaker connections and ensure adequate ventilation.

How do I adjust the crossover?

Use the mode switch to select LPF (low frequencies only), HPF (mid/high frequencies only), or FLAT (full range). Then adjust the Low Pass (30-250 Hz) and High Pass (40-3000 Hz) controllers to set the desired cutoff frequencies.

What is the difference between HPF and LPF?

HPF (High Pass Filter) allows frequencies above the cutoff point to pass, blocking low frequencies. It is used for midrange and tweeters. LPF (Low Pass Filter) allows frequencies below the cutoff point to pass, blocking high frequencies. It is used for subwoofers.

Can I bridge the channels on the GZIA 2080HPX?

Yes, the amplifier supports bridged mode. Connect the positive speaker wire to the left channel (+) and the negative to the right channel (-). The bridged output delivers up to 200 W RMS @ 4 Ω.

What is the input sensitivity range?

The input sensitivity can be adjusted from 200 mV to 6 V using the GAIN controller. This allows matching the amplifier to the output level of your headunit.

How can I prevent the amplifier from overheating?

Ensure adequate ventilation around the amplifier. Do not mount it in an enclosed space without airflow. If the amplifier gets too hot, it will temporarily shut down. Reduce volume or improve cooling.

Does the GZIA 2080HPX include a bass remote control?

No, the GZIA 2080HPX does not include a bass remote control. Some other models in the IRIDIUM series (e.g., GZIA 2235HPX) include one, and the GZIA 2130HPX offers it as an optional accessory.

Tools and materials you need

• Screwdriver
  • Electric drill, 3 mm / 0.12" carbide drill bit
• Mounting screws
  • Power wire min. 10 mm ^4
  • Ground wire min. 10 mm ^4
• Speaker wire min. 2 × 1,5 ~mm^2

Please note!

• As a precaution it is advisable to disconnect the vehicle's battery before making connection to the +12 Volts supply wiring (see owner's manual of your car for further information).
• Please use great caution drilling your trunk. Your gas tank and brake lines can be damaged by puncturing with your drill bit – this could cause damage or failure of your cars operating systems.
• Never pass wires over sharp angles. It is recommended to buffer the power supply of the amplifier with a capacitor min. 1 Farad to guarantee a stable operation voltage.

WARNING!

High powered audio systems in a vehicle are capable of generating "Live Concert" levels of sound pressure. Continued exposure to excessively high volume sound levels may cause hearing loss or damage. Also, operation of a motor vehicle while listening to audio equipment at high volume levels may impair your ability to hear

external sounds such as; horns, warning signals, or emergency vehicles, thus constituting to a potential traffic hazard. In the interest of safety, Consumer Electronics recommends listening at lower volume levels while driving.

Planning your system

Before beginning the installation, consider the following:

a. If you plan to expand your system by adding other components sometime in the future, ensure adequate space is left, and cooling requirements are met.
b. If your radio / source is equipped with pre-amp outputs, it is possible to utilize them to drive the amplifier and connecting (amplifier) to the 2 rear speakers.

Mounting your amplifier

a. Select a suitable location that is convenient for mounting, is accessible for wiring and has ample room for air circulation and cooling.
b. Use the amplifier as a template to mark the mounting holes, remove the amplifier.

Warning

Chose a mounting position where all eclectic wires are protected from being damaged by sharp edges, heat or other conditions. +12Volt DC electrical connections must be fused on the battery side. Make sure your radio and all other devices will be turned off while connection your system.

If you need to replace the power fuse, replace it only with a fuse identical to that supplied with the system. Using a fuse of different type or rating may result in damage to this system which isn't covered by the warranty.

Turning on the amplifier

The amplifier automatically turns on a few seconds after you turn on your radio.

Note: Your amplifier temporarily shuts down if it gets too hot, then restarts automatically once it cools

(At about 80^ / 176^ F).

Adjusting the audio level

1. LEVEL (Min/Max): Turn fully counter-clockwise to MIN position
2. Turn the auto sound system's volume control to about two-third of its full range.
3. Adjust LEVEL to a comfortable listening level.

Connecting the speaker for trimode operation - notes

TRI MODE operation output allows a subwoofer to be operated in mono mode while the main speakers are playing in stereo. Leave the crossover switch on "Full" position.

Use 100 volt, non-polar capacitors for a high pass crossover to filter out low frequencies and Air-core or Ferrit-ore coils with a minimum diameter of 1 mm / 0.039" for the lowpass crossover to filter out high frequencies.

The capacitor and inductor values as written in the below table. The front and rear channels of this amplifier get this capability. Only the rear left and right channels are shown on the following pictures.

Values for 6dB passive crossover

Trouble shooting guide

Symptoms	Check Points	Cure
No sound	Is the POWER LED illuminated?	Check fuses in amplifier. Be sure remote lead is connected. Check signal leads. Check again control. Check tuner/deck volume level.
	Is the diagnostic LED illuminated?	Check for speaker short or amplifier overheating
Amp not switching on	No power to the amplifier	Check power wire or connections
	No power to remote wire with receiver on	Check connections to radio
No sound in one channel	Check speaker leads	Inspect for short circuit or an open connection
	Check audio leads	Reverse left and right RCA inputs to determine if it is occurring before the amp
Amp turning off at medium / high volume	Check speaker load impedance	Be sure proper speaker load impedance recommendations are observed (If you use an ohm meter to check speaker resistance, please remember that DC resistance and AC impedance may not be the same.)
Protection LED is on	Temperature shut down	Turn radio volume down
	Speaker wires short	Separate speaker wires and insulate
