Frequently Asked Questions - GZPA 2.20000SPLHC Ground Zero

The amplifier does not turn on, what to do?

Check that voltage at the +12V and REM terminals (at least 12V) is present. Check the ground and fuses. If the protection LED is on, consult the manual.

The protection LED lights up after power on, what does it mean?

This indicates an overload or short circuit. Disconnect the speaker cables: if the LED turns off, the problem is with the speakers or wiring. Otherwise, the amplifier is defective.

The external fuse blows frequently, why?

Check that the speaker impedance is correct (≥2Ω) and that there is no short circuit in the power cable or chassis. Use fuses of appropriate rating (256A).

The amplifier overheats and shuts off, what to do?

Ensure the speaker impedance is correct and there is no short circuit. Check that the ventilation around the amplifier is sufficient. Let it cool down before reusing.

The sound is too low or distorted, how to adjust?

Increase the car stereo volume to 2/3, then adjust the input level setting on the amplifier to get clean sound without distortion. Check the filter settings.

I hear engine noise or hissing in the speakers, what to check?

Check the RCA cables and ground connection. Disconnect the RCA: if the noise disappears, the problem is with the cables or source. Otherwise, check the speakers and power supply.

How to adjust the low-pass filter and subsonic filter?

The low-pass filter limits high frequencies (e.g., 80Hz). The subsonic filter cuts very low frequencies (e.g., 20Hz). Adjust them according to your subwoofer's specifications.

What is Link mode and how to use it?

Link mode allows connecting two identical amplifiers to double the power on a single speaker. Use the Master/Slave switch and observe a minimum impedance of 2Ω.

How to clean the amplifier?

Use a soft dry cloth to dust the chassis. Never use liquid or abrasive products. Ensure the ventilation slots remain clear.

Where to find spare parts or get the amplifier repaired?

Contact an authorized Ground Zero service center. The warranty does not cover damage due to incorrect installation or abusive use (SPL competitions, etc.).

Introduction Class-D Amplifier

Due to their state-of-the-art technology and high efficiency, these Class-D mono amplifiers help your system to provide an impressive sound experience. The modern circuit technology of the power supply and the signal processing allows achieving maximum performance levels from the provided power.

Due to the different filters and circuits a very high power output is achieved, therefore these amplifiers are made for low frequency information (Subwoofer). They can not be used for high- and midrange speakers.

The link mode enables to use to full power of two amplifiers for one speaker. This is first of all advantageous for a really powerful and lively music playback.

WARNING

High powered audio systems in a vehicle are capable of generating "Live Concert" high level 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 sound such as; horns, warning signals, or emergency vehicles, thus constituting to a potential traffic hazard. For safety reasons we recommends listening at lower volume levels while driving.

Planning your system

Before installation, consider the following notes:

a) Select a suitable location that is convenient for mounting, is accessible for wiring and has enough room for air circulation and cooling.
b) If your radio is equipped with preamplifier outputs (RCA), it is advisable to use them.
c) Please consider the enormous power consumption (up to 1500A) of this amp when designing the setup. We strongly recommend to install an additional battery. Too little power from the battery / alternator may cause defects on your amplifier and your car.

Mounting your amplifier

• Select a suitable location that is convenient for mounting, is accessible for wiring and has ample room for air circulation and cooling.
• Use the amplifier as a template to mark the mounting holes, remote the amplifier and drill 6 holes (use extreme caution, inspect underneath surface before drilling!). Secure the amplifier with the mounting screws.

Using a dual amplifier configuration, the MASTER amplifier has total control over the SLAVE amplifier. When using dual amplifier to operate subwoofer, the positive terminal of the subwoofer's voice coil must be connected to the positive terminal of the MASTER Amplifier and the negative terminal of the subwoofer's voice coil must be connected to positive terminal of the SLAVE Amplifier. Be advised that the dual amplifier configuration has tremendous output potential, so ensure that your subwoofer can handle such a large amount of power.
When utilizing the dual amplifier configuration it is important to note that the connected speaker load can be no lower than 2 ohms. Connecting a lower impedance load can damage the amplifier and void your warranty.

Connections

Please read owner's manual of your car before you disconnect the battery.

+12 Volt (Fused) Constant power: To Battery (+)

Use a strong power cable (50 mm ^4 ) for connection the +12V terminals of the amplifier to the + terminal of your battery.

It is necessary to install 2 (GZPA 1.10000SPL-HC) or 4 (GZPA 2.20000SPL-HC). In-line fuse holders with a maximum distance of 20cm to your battery to ensure a safe operation of the amplifier. Make sure the fuses are not connected when connecting the + cable to the battery- this could cause defects on the device or injuries.

Ground

Disconnect the battery and connect the ground terminals to be vehicle chassis. Is absolute necessary, that the same wire-cross section is used for the ground and +12 V connection. Use a ground wire that is as short as possible (about 25 cm / 10"). To avoid ignition noise caused by ground loops, it is necessary that the amplifiers be grounded to a clean, bare metal surface of the vehicles chassis.

Remote

Connect the Remote terminal with the remote output of your head unit or another 12 V source like your antenna terminal.

Turning on your amplifier

The amplifier automatically turns on a few seconds after you turn your vehicle's ignitions switch to ACC ON or turn on your auto sound system, depending on how you wired the system.

Note: Your amplifier temporarily shuts down if it gets too hot, then restarts automatically once it cools down. The input level must be adjusted correctly to provide a good performance of the amplifier (200mV - 10V).

Adjusting the audio level / Input sensitivity

Step 1 Turn the input level controller fully to MIN in counterclockwise direction.

Step 2 Turn the auto sound system's volume control to about two-third of its full range.

Step 3 Adjust the auto sound system's volume control to a comfortable listening level.

Please note – The gage on a CD, that reproduces music with a higher dynamic is essential higher as on Radio reception.

Trouble shooting

This power amplifier has protection features to prevent any damages from misuse or faulty conditions. If the unit senses excessive heat, short circuited speakers or overload, the protection indicators will light, and the system will be turned off. In order to check the occurred problem, you should turn all levels down and all power off and carefully check the installation for wiring mistakes or short. If the amplifier shuts down due to excessive heat, the protection indicators will not light: simply allow time for the unit to cool. Before removing your amplifier, refer to the list below and follow the suggested procedures. Always test the speakers and their wires first.

Problem Check points
Amplifier is not powered up	Check that there is battery power on the +12V terminal.Check that remote terminal has at least +12V DC remote connection.Check a good ground connection. Check all fuses.Check the protection LED is not lit.
Protection LED illuminates when amplifier is powered up	Check shorts on speaker wires.Remove speaker wires and reset the amplifier.If the protection LED still comes on, then the amplifier is faulty.
Fuse blowing	Check that the minimum speaker impedance is correct.Check short on power cable and vehicle chassis.
Overheating	Check that the minimum speaker impedance is correct.Check speaker shorts.Check that there is a good airflow around the amplifier.
Sound too low / Distorted sound	Check that the input level control is set to match the output level of the unit.Check the head unit volume.Check speaker shorts.Check that crossover frequencies have been properly set.
High hiss / engine noise in speakers	Check a good ground and for speaker shorts.Disconnect all RCA inputs from the amplifier.If hiss/noise disappears, check it with a good RCA interconnect. Then check the component driving the amplifier.
