Step 3:
Install Loudmouth in
LMH-100 Enclosure
Install the Loudmouth receiver into the LMH-
100 enclosure using the four Seal Screws
(28151607) included with the LMH-100. The
screws are inserted into the four holes on the
corners of the Loudmouth case and threaded
into the LMH-100 mounting plate (25110100)
that was pre-installed at the factory.
Step 4:
Install Antenna
Connect the AFB-1545 antenna to the antenna
connector on top of the Loudmouth receiver.
The antenna is then routed along the left side
of the LMH-100 enclosure and secured with the
Antenna Location Clip (25204800) that was
pre-installed at the factory.
Step 5:
Replace Loudmouth Case Top
Re-install the Loudmouth receiver case top that was removed in Step 2 by tightening the 4 plastic corner screws. Do NOT
over-tighten the plastic screws.

IMPORTANT
The Loudmouth power and speakers cables can be routed from the LMH-100 enclosure in a variety of ways, depending on
the specific installation. Steps 6 through 8 describe the installation of the weatherproof strain relief that was included with
the LMH-100.
An alternative method is to install electrical conduit. Carefully consider your installation before drilling holes in the LMH-100
housing. Be sure there will not be interference with the internal parts, and that the cable and connectors can be routed
through the conduit to the connectors on the bottom of the Loudmouth receiver.
Step 6:
Drill LMH-100 Enclosure
for Strain Relief (Optional)
A hole can be drilled in the bottom of the LMH-100
enclosure to route the Loudmouth power and speaker
cables. The instructions in this manual describe the
installation of the weatherproof strain relief
(25204500, 25204600) and plug (25204700) included
with the LMH-100.
1. Carefully measure and mark the location
of the hole on the bottom of the LMH-
100 enclosure per the diagram at right.
2. Drill a .875 (7/8) hole in the bottom of the LMH-
100 enclosure. Remove all residual plastic after
drilling and thoroughly clean the area.
.875” (7/8)
5.046”
1.00”
WARNING: The location of this hole is critical to the
successful routing of the power and speaker cables
and cannot be compromised.

Step 7:
Install Weatherproof
Strain Relief (Optional)
1. Remove clinching nut from strain relief
(25204500)
2. Insert strain relief (25204500) fully through
the hole in the LMH-100 enclosure
3. Secure strain relief (25204500) to the LMH-
100 enclosure with the strain relief nut
(25204600)

Step 8:
Connect Loudmouth Power and Speaker Cables through
Strain Relief (Optional)
1. Route the Loudmouth power and speaker
cable connectors through the strain relief
clinching nut that was removed in Step 7.

2. Route the Loudmouth power and speaker
cable connectors through the strain relief
installed on the LMH-100 enclosure.
3. Connect the power connector to the
Loudmouth DC power jack on the
Loudmouth case (left side jack), and the
speaker connector to the phono jack on the
Loudmouth case (right side jack).
4. Insert through the strain relief enough length
of both cables to create a loop as shown at
right.
5. Use a plastic cable tie (02800088) to secure
both cables to the LMH-100 mounting plate
(25110100). Thread the cable tie through
the hole in the mounting plate and tightly
secure both cables.
6. Press the rubber strain relief plug
(25204700) into the strain relief installed on
the LMH-100 enclosure, between the
speaker and power cables. The plug should
be fully inserted into the strain relief.
7. Tighten the strain relief clinching nut onto the
strain relief to compress the plug and seal
the cables.

Step 9:
Install the LMH-100 Enclosure
The LMH-100 may be installed to a wide variety of surfaces and materials. For this reason, mounting hardware is not
included with the LMH-100. LMH-100 mounting is accomplished using the four 0.32” diameter holes pre-drilled in the
enclosure as indicated below.
WARNING: Do not attempt to mount the LMH-100 enclosure by drilling additional holes. Additional holes may compromise
the weatherproof integrity of the enclosure.

Step 10:
Install Optional Sealed Gelcell Battery
The Loudmouth can be powered with an optional 7AH gelcell battery (RTN# 04000064) installed in the LMH-100 enclosure.
The gelcell battery is connected to the Loudmouth using the optional LMK-BP cable assembly.
1. Install gelcell battery (04000064) as shown and tightly secure to the LMH-100 mounting plate (25110100) using the two
velco straps (25204300) that were pre-installed at the factory.
2. Connect the black lead of the LMK-BP cable assembly to the negative (black) terminal of the gelcell battery.
3. Connect the red lead of the LMK-BP cable assembly to the positive (red) terminal of the gelcell battery.
4. Connect the DC coaxial power connector of the LMK-BP cable assembly to the Loudmouth DC power jack on the
Loudmouth case (left side jack).
NOTES:
•The optional gelcell battery cannot be used in conjunction with the DC power cube (RPS-1A) that comes with the
Loudmouth.
•The gelcell battery can be charged with the battery removed from the enclosure, or while installed, using a
commercially available 12VDC, 1A gel cell charger.
•When selecting a charger make sure it is designed for charging sealed gel cell batteries. Standard automotive
chargers generally charge at a rate that exceeds maximum charge current for a sealed battery.
