CAUTION
Prior to installing the amplifier, disconnect the negative (ground) wire from the
vehicle’s battery. This will prevent accidental damage to the system, the vehicle
and your person during installat
ion.
The Q series amplifiers power and ground connections are designed to accept 4 AWG
power wire. 4 AWG is the minimum recommended power wire size for this amplifier. If
you are installing multiple amplifiers and wish to use a single main power wire, use 2
AWG or 1/0 AWG main power wire (depending on total system current demands). The
main 2 AWG or 1/0 AWG power wire should terminate into a distribution block mounted
as close to the amplifiers as possible and should connect to the amplifier with 8 - 4 AWG
power wire.
The ground connection should be made using the same gauge wire as the power
connection and should be kept as short as possible, to a solid piece of sheet metal in the
vehicle. The surface of the sheet metal should be sanded at the contact point to create
a clean, metal-to-metal connection between the chassis and the ground wire termina-
tion. For proper grounding use a bolt with a star washer, a #10/12 sheet metal screw can
be used alternately.
Any wires run through metal barriers (such as fire walls), must be protected with a high
quality insulating grommet to prevent damage to the insulation of the wire. Failure to do
so may result in a dangerous short circuit
.
NOTE:
Many vehicles use small gauge wire to ground the battery to the vehicle chassis
and to connect the alternator to the battery. These wires should be upgraded to 4 AWG
when installing large or multiple amplifier systems exceeding 500 watts.
FUSES
It is required that the main power wire to the amplifier(s) in the system be fused within 18
inches of the positive battery connection. The fuse value at each power wire should be
high enough for all of the equipment being run from that power wire. If only an individual
amplifier is being run from that power wire, we recommend a fuse equal to the amplifiers
fuses be used. No fuse is required or recommended directly before the amplifier power
REMOTE TURN-ON
The Q Amplifiers uses a +12V remote turn-on
lead, typically controlled by the source
unit’s remote turn-on output. The amplifier
will turn on when +12V is present at its
“Remote” input and turn off when +12V is
switched off. If a source unit does not have
a dedicated remote turn-on output, connect to
+12V circuit controlled by the ignition switch.
