USER MANUAL GZPA 1.10000SPLHC Ground Zero

Please read before installation Thank you for selecting a GROUND ZERO Plutonium amplifier. We are providing a helpful hints list which should keep you from experiencing unnecessary shut down 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. Features

• 4 x 50mm² Battery/Ground terminals (GZPA 2.20000SPL-HC)Tools and materials you need

• 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.

• Take care of square edges, the cable could be rub through. 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. RCA Connections – Single mode GZPA 1.10000SPL-HCRCA Connections – Link mode GZPA 1.10000SPL-HC

Amplifier connections GZPA 2.20000SPL-HCConnections 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 mm²) 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 20 cm 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 tot he vehicle chassis. Is absolute necessary, that the same wire-cross section is used for the ground and +12 V connection. Use s 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.Specifications
