Q-Link Capability

The Quantum Audio QRM3000 , QRM4000 and QRM 5000 have an internal linking

circuit that allows you to link two like model amplifiers so that you can double your

output power to a single load.

When linking two like amplifiers they are split up into master and slave units.

The master amplifier becomes the main control for all input signals and gain

controls.

Before you start the installation, it will be necessary to find a mounting location for the

amplifier. Find a location in which the amplifier will receive adequate ventilation in order

to dissipate the heat it develops during operation. Two popular mounting locations are in

the trunk or under the seat.

Select the location in which you wish to mount the amplifier. Use caution when mounting

amplifier, there are many wires, gas lines, vacuum lines, brake lines as well as a gas tank

in the automobile. Make sure you know where they are when mounting the amplifier to

avoid puncturing lines, shorting wires or drilling holes in the gas tank. Once you are

ready, use a pencil to mark the mounting holes in the bottom panel. After you have

marked the locations of the holes move amplifier out of the way and drill small starter

holes to make the tapping screws easier to install. Use provided screws to tighten down

the amplifier.

Connect The Amplifier To The Car's Battery

At times, the amplifier will need to draw large levels of current that cannot be provided by

any circuit in the car's fuse box. We recommended using a 4 to 8 gauge power wire for

your connections depending on the amplifier and length of the wire. Strip one end of the

wire to connect to the terminal on the amplifier marked “+12V”. Loosen screw terminal

and connect bare wire and tighten. Use caution to make sure no stray wire strands come

in contact with surrounding terminals causing short circuits. Run the wire directly to the

positive terminal of the car's battery. Make sure to use an in-line fuse within 12” of the

car's battery to protect the electrical system and amplifier against short circuits and/or

power surges.

Connect The Ground Terminal Of The Amplifier To The Car's Chassis

For the ground connection, use a 4 to 8 gauge wire (black) to connect to the terminal

marked “ground” and then connect it to the car's chassis. Try to keep the length of the

cable as short as possible, preferably less than 6". Also make sure that the point on the

car where the connection is to be

made is free of paint and dirt.

Connect The Remote Terminal Of The Amplifier ToASwitchable +12V Source

This connection allows the amplifier to be turned on and off with the power control of the

radio. If the radio has a REMOTE output terminal, connect it to the amplifier's terminal

marked “remote” (using a 16 gauge wire or heavier). Now when the radio is turned on,

the amplifier will automatically turn on. This connection can also be made to the radio’s

Power Antenna wire.

IMPORTANT! Before making any connections, disconnect the car’s battery until the

installation is completed to avoid possible damage to the electrical system.
