JBL Stage A6004 Owner's Manual page 3

Precautions:
IMPORTANT: Disconnect the vehicle's negative (–) battery terminal
before beginning the installation.
• Always wear protective eyewear when using tools.
• Choose a safe mounting location, away from moisture. Check
clearances on both sides of a planned mounting surface. Be sure that
screws or wires will not puncture brake lines, fuel lines, or wiring
harnesses and that wire routing will not interfere with the safe vehicle
operation. Use caution when drilling or cutting in the mounting area.
• When making electrical connections, make sure they are secure and
properly insulated.
• If you must replace any of the amplifier's fuses, use the same type of
fuse and current rating as the original.
• To keep the amplifier cool, choose a location that provides enough air
circulation, such as under a seat or in the trunk.
• Do not mount the amplifier with the heat sink facing downward, as this
interferes with cooling.
• Mount the amplifier so that it will not be damaged by the feet of
backseat passengers or shifting cargo in the trunk, and so that it
remains dry.
• Using the amplifier as a template, mark the locations of the holes on
the mounting surface.
• Drill pilot holes in the mounting surface.
• Attach the amplifier to the mounting surface with four appropriate
mounting screws (not included). Recommended: #8 Phillips-head
sheet metal screws.
NOTE: You may find it more convenient to make all of the
connections to the amplifier before you permanently mount it.
� Power/protect indicator:
The light will illuminate in blue when the amp is receiving power and
playing. The indicator will illuminate in red if the amp enters Protect
mode in the event of conditions such as over/under voltage, short
circuit, amplifier output circuit failure, or excessive heat.
� Power Input Connectors:
• Power: Run power wire from the
+12V input to the positive terminal of
the vehicle's battery. Insert bare wire
into the terminal on the amplifier, then
tighten the setscrew with a Phillips
screwdriver.
• Install an appropriate fuse holder and fuse (20A minimum for Stage A6002
and 30A minimum for Stage A6004 and A3001, and 40A minimum for
A9004) within 18" (457mm) of the battery. Make sure the wire is not
damaged or pinched during installation. Install protective grommets when
routing wires through the bulkhead or other sheet metal. Use larger-gauge
wiring for longer runs.
o Stage A6002 minimum wire size: ≥10 gauge
o Stage A6004, A9004, A3001 minimum wire size: ≥8 gauge

• Ground: Run a wire (the same gauge as the power wire) from the GND
input to a factory bolt in the vehicle's chassis (see illustration below).
NOTE: Remove any paint from the chassis for best contact. Use a star
washer below the ring connector for a secure connection.

Note: Remove any paint
below ring connector
• Remote: Connect a 20-gauge wire from the "Remote Out" lead of the
source unit to the REM input. This lead turns the amplifier on when using
low-level input signals. If your stereo has no "Remote Out" lead, connect the
amplifier's REM input to switched accessory power.
� Fuses:
• Replace only with fuses of the same amperage:
o Stage A6002: 20A
o Stage A6004 and A3001: 15A x 2
o Stage A9004: 20A x 2
� Speaker Output Connectors:
Connect the speakers to these terminals, observing proper polarity (connect
each speaker's positive (+) lead to the appropriate positive (+) terminal, and
negative (-) lead to the appropriate negative (-) terminal.
Stage A6002
• The Stage A6002 features L+, L-, R+, and R- terminals.
• 2-channel operation: Connect the left speaker to the L+ and L- terminals,
and the right speaker to the R+ and R- terminals.

o Bridged operation: Connect the positive wire from the single
speaker or subwoofer to the R+ terminal, and the negative wire
from the speaker or subwoofer to the L- terminal.
