IMPORTANT

PLEASE READ ALL INSTRUCTIONS BEFORE INSTALLATION !

The quality of installation may affect the performance and reliability of your product. If you have any doubts or questions regarding installation, you may wish to contact your authorized dealer. Remember to heed all wire and fuse requirements suggested in this manual. Warranty may be void if proper installation technique is not used (refer to warranty section in the rear of the manual )

INSTALLATION

MOUNTING:

1. After reading precaution, decide where you are going to install the unit. Also, see Fig.1.

2. Once the location has been determined, place the amplifier into position. Using a felt tip

pen or pencil mark the four holes to be drilled for mounting. NEVER use the amplifier as

a template for drilling. It is very easy to damage the amplifier surface in this manner.

3. Remove amplifier. Drill four 3.5 m/m holes into mounting surface. If you want to mount the amplifier to MDF or wood panel, drill four 3.0m/m diameter holes into mounting surface.

4. If possible, test the system to ensure it is operating correctly before final mounting of the amplifier.

5.

Mount the amplifier using the supplied 4 self tapping screws.

FIG.1

SPEAKER WIRING

The Class "D" amplifier is a SINGLE CHANNEL dedicated subwoofer amplifier. Unlike other amplifiers, the Class "D" operates as a single channel and cannot be bridged.

Don't be fooled by the outputs. Two outputs are used strictly for convenience and are paralleled internally on the amplifier. This means that if both outputs are used with one driver each, the amplifier sees the same load as if the same drivers are connected to only one output terminal. See diagram below.

WIRING SUBWOOFERS (DUAL AMPS)

When using dual amplifiers to power one subwoofer, the Positive terminal of the Subwoofers voice coil is connected the positive terminal of the MASTER Amplifier and the Negative terminal of the Subwoofers voice coil is connected to Positive terminal on the SLAVE Amplifier. This procedure will allow the total power of both amplifiers to be added together and act like a single powerful amplifier. Please check that your subwoofer power handling capabilities are not exceeded

when hooking two amplifiers to it.

CAUTION

Always check your speaker load with a multi-meter before hooking up to the amplifier. These digital amplifiers are only 1 ohm stable. Any Impedance (load) smaller than 1 ohm will damage the amplifier. Such Damage is not covered under warranty either, so pay strict attention to what connections are made to the amplifier.

POWER SUPPLY CONNECTIONS

The Class "D" amplifier is designed to work within 10 to 16 volts DC. Before any wires are connected, the vehicle's electrical system should be checked for correct voltage supply with the help of a voltmeter. First check the voltage at the battery terminals with the ignition in the off position. The voltmeter should read no less than 12 volts. Next, check the battery with the engine running between 1500 and 2000 rpm. The voltmeter should now read between 13.5 and 14.5 volts. If your vehicle's electrical system Is not up to these specifications, we recommend having it checked by an automotive mechanic before further installation.

RECOMMENDED POWER WIRE

Class "D" amplifier is capable of drawing in excess of 90 amperes,4 gauge wire is wire may be necessary.

POWER

Amplifier power wire should be wired directly to the battery using the wire requirements listed above. Start at the amplifier and run the power wire through the vehicle to the battery. The use of grommets is recommended when passing the power wire through any metal wall. Avoid sharp corners or sharp body parts that may easily cut through the insulation on the wire. Avoid running the power wire over engine components and near power wire. Connect the fuse holder as close to the battery positive as possible. For most applications, an 80 ampere Maxi fuse or comparable ANL wafer fuse can be used.

Now connect the wire to the battery, but remember to leave the fuse out until all other wire connections are mode.

G R O U N D

When grounding your amplifier, locate a metal area close to the amplifier that is a good source of ground ( preferably the floor ).Once again, investigate the area you wish to use for electrical wires, vacuum lines, and brake or fuel lines. Using either a wire brush or sandpaper eliminate unwanted paint to supply a better contact for your ground. Use the same gauge wire for ground as you did for the power. Terminate the ground wire using the correct size ring terminal and attach it to the bare metal using a nut and bolt. It is important for this connection to be solid. To complete the job, spread silicon over the screw and bare metal to prevent rust and possible water leaks.

REMOTE TURN-ON

In between the power and ground is a remote turn-on terminal. This terminal must be connected to a switched +12volt source. Typically, remote turn-on leads are provided at the source unit that will turn on and off the amplifier in correspondence with the source.

If a radio does not have a remote turn-on, then a power antenna wire may be used. Yet, if neither of these leads are available at the source, a switched +12 volt supply must be supplied. Run a minimum of 18-gauge wire from the amplifier location to the source of the switched +12 volt lead. If possible, route this wire on the same side of the vehicle as your power wire. Connect the source remote output wire to the REM terminal on the amplifier using a 3mm screw key. Cut the remote wire to length. Strip approximately 1/2 inch of insulation from the end of the wire and insert into the terminal. Tighten the screw securely.

Control and Crossover

1. RCA Input Jacks - Low level-high impedance inputs. Use high quality RCA cables designed

for mobile applications.

2. Input Level Control - Adjust the input level for the marked channels. Turn clockwise to

increase the level, counterclockwise to decrease. Amplifiers will run cooler and produce

less system noise at lower level settings.

3. Low Pass Frequency - Adjust the crossover frequency by turning clockwise to set to a higher

frequency, counterclockwise to set to a lower frequency.

4. Bass Boost - Adjust the sub boost level of the selected frequency output from 0dB to 12dB.

5. Remote Control Jack - For connecting the remote control module to the amplifier.

6. Master/Slave Switch - Select the remote level control or the on-board level control as the

master control.

7. Slave Input Jack - Used to connect to another amplifier when bridging 2 amps together.

The Slave mode bypasses normal input jacks and controls.
