Introduction

Amplifiers provide high-performance sound reinforcement for your mobile audio equipment.

It's versatility enables compatibility with optional Equalizer, Frequency Dividing Network

Crossovers and other audio processors in a customized system. The Multi-Mode bridging

capabilities allow flexibility in hosting several different speaker configurations.

To achieve optimum performance, it is highly recommend that you read this Owners manual

before the installation.

Tools and materials you need

• Screwdriver
  • Electric drill, 3mm
• Mounting screws
  • Power wire min. 20mm²
  • Ground wire min 20mm²
• Speaker wire min. 2 × 1.5 ~mm^2

Attention

• 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!)
• Do not drill holes into the tank, the brake pipe, wires or other important parts of the vehicle.
• Never pass wires over sharp angles. It is recommended to buffer the power supply of the amplifier with an capacitor min. 1 Farad.

WARNING

High powered audio systems in a vehicle are capable of generating „Live Concert" high 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 sound 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 an equate space is left, and cooling requirements are met.
b. If your radio/source is equipped with Pre-Amp outputs, it is recommended to utilize them to drive the amplifier.
c. Are your components matched? The peak power rating of your speakers must be greater than the Amplifiers. They also must be 2-8 Ohms impedance (This information is normally printed on the speaker magnet.)
d. Consider both the length of your leads, and routing when choosing the mounting location. Pre-Amp input jacks require a length of high quality shielded male to male RCA patch cord.

Mounting your amplifier

a) Select a suitable location that is convenient for mounting, accessible for wiring and has enough room for air circulation and cooling.
b) Use the amplifier as a template to mark the mounting holes, remove the amplifier and drill 4 holes, use extreme caution, inspect underneath surface before drilling.

Warning

Investigate the layout of you automobile thoroughly before drilling or cutting any holes. Take care when you work near the thanks, lines, or hydraulic lines, and electrical wiring. Don't mount this system so that wire connections are unprotected or are subject to pinching or damage from nearby objects.

The +12 Volt DC power wire must be fused at the battery positive terminal connection. Before making or breaking power connections at this system power terminals, disconnect the +12 Volt wire at the battery end.

Confirm your radio / cassette player and / or other equip, mount is turned off while connecting the input jacks and speaker terminals.

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.

Wiring connection

Attention! - min. 20mm^2 wires are necessary for power connection!

(1) Ground: Ground connection should be passed directly to the car body as short as possible (max. 1m)
(2) +12 Volt: Power connection should be passed directly to the battery. Please pay attention on a correct fuse protection of the installation with an Inline device with a max. wire length to the battery of 30 cm.
(3) Remote turn on: This connection is getting connected with the remote control line of the radio. It is used for turning on and off the amplifier.

High Input

If your head unit is not equipped with a Cinch output for driving an amplifier, you can connect the speaker outputs directly to the high input of the amplifier. It is rarely possible (depending on the used car stereo) that this operation mode leads to interferences. To avoid or clear them, you should connect the GND cable of the high input directly to the ground connection (GND) of the power terminal.

These are driven by the line output of your in dash radio or intermediate signal processor. Separate left and right signals can be applied for stereo or mono operation but both inputs must be driven with the same signal for proper bridged operation. If only mono signal is available, a Y-adapter is required.

Adjusting the audio level

For the best performance, you must set LEVEL (MIN'MAX) on the side of the amplifier to adjust the level of the audio signals.

1. Use a screwdriver to turn LEVEL(MIN/MAX) fully to MIN
2. Turn the auto sound system's volume control to about two-third of its full range.
3. Adjust LEVEL(MIN/MAX) to a comfortable listening level
4. Turn up the auto sound system's volume control until the sound begins to distort.
   Then immediately turn the volume down to a point just before where the distortion began.
   Caution: Never turn up the auto sound system's volume control more than needed to adjust the audio level, more than two thirds of its maximum volume.
5. Adjust LEVEL (MIN/MAX) until the sound is at the maximum level you want the amplifier two produce.
6. Adjust the auto sound system's volume control to a comfortable listening level.

Trouble shooting

This power amplifier has protection features to prevent any damages from misuse or faulty conditions. If the unit some excessive heat, short circulated 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 in.
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.
