4.
Drill a 9/16" (15mm) hole for the power switch at least 1"
above the DC power hole and in the center of the ammo
box. If using a 9/16" drill bit you may have to ream it out
a little for the switch to fit. Make sure it’s a tight fit. Wait
to install the switch until the wires are ready.
5.
Correctly install the 18650 batteries by matching the
polarity of the board to the polarity of the batteries.
The dimple in the battery is the + side.
6.
Install the battery board to the aluminum L-bracket
with the 2.1 x 5.5mm DC jack facing away from the L
side of the bracket and the batteries facing the bracket
with 10mm standoffs and included M3 screws.
7.
Place two 3" strips of the included double-sided tape to
the L-bracket and install the bracket so it lines up with
the DC jack on the battery board. Stack two to three
small strips of double-sided tape together and use a
paper hole punch to make a hole in the stack. Place the
tape between the DC jack and the hole in the ammo
box to help keep it sealed. Once the battery board
is securely installed, place a piece of paper over it to
prevent any metal from touching the board.
8.
Install the speakers by carefully placing the terminals
in first. Drill 1/32" pilot holes for the included #6 black
screws. Tighten the screws in a cross pattern.
1.
Start by cutting two 2
"
holes for each speaker. The
bottom of the speaker hole should be 1-3/4
"
from
the bottom of the ammo box. The holes should also
be 5/8" from the outside edge of the ammo box. A 2"
hole saw works well if available.
2.
At the top of each hole cut out 1-1/2" W x 3/8" to
make room for the speaker terminals. Use a Dremel
tool for this cutout if available. Jigsaw might crack the
plastic. Insert speakers to make sure the hole is large
enough, but don’t permanently install the speakers
until the battery board is in place.
3.
In the rear of the ammo box drill a 1/4" hole 3-1/2"
from the right edge of the ammo box and 9/16" from
the bottom of the ammo box. This will line up with the
power jack on the battery board when it’s installed.
