Power and turn-on connections
Before 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 body during installation.

You will need to connect a power wire to
the vehicle’s positive battery terminal, using
an appropriate power ring or specialized
battery terminal connector, such as the JL
Audio XB-BTU or XD-BTS. This connection
must be tight and corrosion-free to ensure
proper connectivity. This wire MUST be fused
appropriately for safety. Any power wires run
through metal barriers (such as firewalls), 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.
Power wire requirements
The HD1200/1’s “+12 VDC” and “Ground”
connections are designed to accept 4 AWG power
wire. 2 AWG or 1/0 AWG pure copper wire is
recommended for any power wire run longer
than 72 inches (180 cm). This larger wire should
be reduced to 4 AWG using a distribution block
within 36 wire inches (90 cm) of the amplifier’s
“+12 VDC” connector. For runs shorter than
72 inches, 4 AWG pure copper power wire is
acceptable.
If you are installing the HD1200/1 with other
amplifiers and wish to use a single main power
wire, use 1/0 AWG pure copper wire as a main
power wire. This 1/0 AWG power wire should
terminate into a fused distribution block mounted
as close to the amplifiers as possible and should
connect to the HD1200/1 with 4 AWG pure
copper power wire.
Please note that lower AWG numbers mean
bigger wire and vice-versa (1/0 AWG is the largest,
2 AWG is smaller, then 4 AWG, then 8 AWG, etc.).
We do not recommend the use of “copper-
clad aluminum wire” or “CCA” wire because
this wire is significantly less conductive than
pure copper wire. Only use pure copper power
wire, such as JL Audio’s Premium Power Wire.
Tinned copper wire (silver color) is acceptable
as the tin-plating is only a very minor
component of the wire.
Fuse requirements
The installation of a fuse on the main power
wire, within 18 wire inches (45 cm) of the positive
battery terminal is vital to protect the wire and
the vehicle from fire in the event of a collision
or short-circuit. The fuse value at each power
wire should be just high enough for all of the
equipment being run from that power wire. Do
not use a fuse with a value that far exceeds the
total fuse rating of the electronics connected to
the wire.
If only the HD1200/1 is being run
from that power wire, we recommend a
100A fuse be used. MaxiFuse™ (big plastic-
body fuse) types are recommended.
If other amplifiers are also being powered
from a main power wire and all the amplifiers
together exceed 100 amps in total fuse rating,
we recommend the use of an ANL (large-blade)
fuse and holder at the battery plus a fused
distribution block near the amplifiers. Each
amplifier must be fused independently at the
outputs of the fused power distribution block.
We recommend appropriately rated MaxiFuse™
fuses and a JL Audio fused distribution block.
Please consult with your JL Audio
dealer to make sure that the wire, fuse
holder and fuse ratings are appropriate
for your system’s needs. The safety of
your installation depends on appropriate
power connections and fuse protection.
