10. OPTION AND ACCESSORY INSTALLATION
10.1 SPEAKER INSTALLATION
Ensure the speaker is adequately protected if it could be exposed to a harsh environment,
such as water and hose-down, snow, dust, smoke, gases, road debris, oils, chemicals
and corrosive agents.
10.1.1 Front-Mount Radio Installation
In a front-mount radio installation, total speaker cable length (of both cables) is approximately 10 feet
(308 centimeters). Therefore, to include service loops in these cables, the speaker must be mounted within
approximately 9.5 feet (290 centimeters) of the radio.
1. Select a location for the speaker that will allow for proper listening range at moderate volume.
2. Install the speaker using the hardware and mounting bracket supplied with it. For the speaker’s part
number, see Section 4.
3. Route the speaker cable to the rear of the radio.
4. Connect Option Cable 14002-0174-50 to the DB-44 connector on the rear of the radio. Tighten the
cable’s two (2) jackscrews securely. See Section 11.1 for additional information on this cable.
If the approximate speaker cable length of 10 feet is not long enough, 20-foot Speaker-
Only Option Cable 14002-0174-52 can be used in place of Option Cable 14002-0174-50.
However, Speaker-Only Option Cable 14002-0174-52 does not support any optional
connections at the 44-pin (DB-44) connector on the rear of the radio. Use of Speaker-
Only Option Cable 14002-0174-52 will provide approximately 25 feet of total cable
length for the speaker connection.
5. Mate the Option Cable’s 2-pin connector (identified P2 with green and white wires) to the 2-pin
connector on the end of the speaker cable. A mild click will be sensed to confirm proper mating.
6. Route the cables out of the way of casual contact. Tie and stow as necessary.
10.1.2 Remote-Mount Radio Installation
In a remote-mount mobile radio installation with a Control Head, an audio amplifier in the Control Head
drives the external speaker.
For either case, total speaker cable length of both cables between the Control Head and speaker is
approximately five (5) feet. Therefore, to include service loops in these cables, the speaker must be mounted
within approximately 4.5 feet of the installation’s Control Head.
1. Select a location for the speaker that will allow for proper listening range at moderate volume.
2. Install the speaker using the hardware and mounting bracket with which it is supplied.
3. Route the speaker cable to the rear of the Control Head.
4. Mate the 6-inch speaker cable to the 2-pin connector at the rear of the Control Head by visually aligning
the ¾-moon-shaped keys of the connectors, and then pushing and turning the outer locking ring of the
cable connector clockwise until it stops. A mild click will be sensed to confirm proper mating.
