Use the 18 gauge
speaker wire and
crimp the large quick
disconnect to the red
wire and the small
quick disconnect to
the black wire. Always
strip at least 1/4" of
the insulator off to
expose the bare wire
and twist the bare
strands together
before crimping. One speaker wire should be around
11" and the other wire around 8". The bare wire ends
will go into the left and right speaker terminal screws
on the amp board.
10.
Use the black and red power wire with the black plug
that came with the battery board to wire to the switch.
Cut 5" away from the black plug both the red and black
wire. Crimp a quick disconnect to the red 5" wire. Place
both bare wire ends of the black wire into one quick
disconnect and crimp it. Identify the bronze terminal on
the switch and push the switch into the hole you made
in the ammo box. The black wire hooks to the bronze-
colored terminal on the switch and the other black
bare wire end hooks to the – power screw terminal
on the amp board. The red wire hooks to the center
silver terminal. Crimp the remaining quick disconnect
to the remaining red bare wire and hook it up to the
outer silver terminal. The other end of the bare red
wire goes to the +
power terminal screw
on the amp board.
Remove the paper
that was suggested
to cover the battery
board. Connect the
black power plug
to the black power
socket on the
battery board.
Make sure
all the wires
are securely
crimped inside
the quick
disconnects.
Soldering is
always better, but to make this kit solderless we had to
use quick disconnects. Secure the amp board to the lid
of the ammo box with the remaining double-sided tape.
Lift and carefully twist the IR silver receiver so the black
dot faces the front of the ammo box.
11.
Plug the power supply into the DC power jack in the
back of the ammo box to kick start the batteries. Turn
the power switch on and sync your Bluetooth device to
the amp board. Turn the volume up to 3/4 and close
the ammo box lid making sure none of the wires get
pinched. Pull the battery protect tab out of the remote
and play your favorite song. Point the remote at the
front of the ammo box to adjust the volume and EQ
settings. Make sure you charge the batteries all night.
You can turn the ammo box off with the remote, but
you’re in standby mode which still slightly drains the
batteries. Turn the power switch in the ammo box off to
reserve battery power. If you turn the power switch on
and noticed that the box has no power, plug the power
supply in for 5 seconds to kick start the battery board.
Additional Options
12.
Additional things can be done to improve the sound.
Adding Acousta-Stuf Polyfill might help to prevent a
hollow-sounding ammo box. Small base ports might
give you a little extra bass.
13.
To protect the speakers use a small speaker grill or
metal fan guard.
14.
Cut holes in the front of the ammo box to manually
increase volume, use the line input, and insert flash
drives externally. The only mounting support would
be from the volume shaft nut and you would lose the
sound seal.
