Wiring Instructions
When working with power connections it is always recommended that you
disconnect the negative terminal from the car battery to prevent accidents.
(Fig. 1) Nothing quite makes your day like a positive voltage wire touching
the car chassis or your gear and making sparks fly, blowing fuses or breaking
your equipment. Disconnecting the negative terminal from the car’s battery
will nip this problem right in the bud.
To make wiring the power connections to the KQ30 easier, you can remove
the power plug, terminate your wires into it and then re-insert it after all
wiring is completed. (Fig. 2)
The ground should be connected to the
equalizer first before making any of the other
connections. This wire should be as short as
possible (36 inches or less) and connected to a
paint/corrosion free solid metal area of the
car’s chassis using 18 Ga wire and a small ring
terminal. (Fig. 2 and Fig. 3)
Connect the +12V terminal to a constant 12
volt battery source using 18 Ga wire and an in-
line 5 amp fuse. The KQ30 itself has a 2 amp
chassis fuse for protection. The additional 5
amp in-line fuse is to protect the wire feeding
the KQ30 and should be placed as close as pos-
sible to the battery. (Fig. 2)
If you have a fused distribution block in the
rear of your vehicle to distribute power to your
amplifiers and it has an extra tap, you can use
this in place of the in-line fuse as long as you
still fuse it for 5 amps. (Fig. 3)
The turn on terminal is connected to your
source unit’s remote turn-on lead. Most source
units have an output labeled ‘power antenna’
or ‘amplifier turn-on’ for this connection. If
your source unit has both, use the output
labeled ‘amplifier turn-on’. (Fig. 2 & Fig. 3)
After making all your power connections you
can re-insert the power plug into the KQ30 and
re-connect your
negative battery
cable to your car
battery. (Fig. 4)
