Making Connections; Speaker Connection - Sony MEX-M100BT Operating Instructions Manual

*1 Not supplied
*2 Speaker impedance: 4 – 8 Ω × 4
*3 RCA pin cord (not supplied)
*4 Depending on the type of boat, use an adaptor for a
wired remote control (not supplied).
*5 Whether in use or not, route the microphone input
cord such that it does not interfere with driving
operations. Secure the cord with a clamp, etc., if it is
installed around your feet.
*6 For details on installing the microphone, see
"Installing the microphone" (page 35).
*7 Use speakers with 50W RMS or higher power input
capacity. Using Sony XB series full range speakers is
recommended.
*8 When the amperage rating of the fuse used on your
boat is 10 A, make the power connection to the
battery directly to avoid short circuits.
*9 Supplied with the marine remote commander.
*10 Not waterproof

Making connections

 To a boat's illumination signal
Be sure to connect the black ground (earth) lead
to the battery or distribution block ground first.
 To the power antenna (aerial) control lead or
the power supply lead of the antenna (aerial)
booster
It is not necessary to connect this lead if there is
no power antenna (aerial) or antenna (aerial)
booster, or with a manually-operated telescopic
antenna (aerial).
To AMP REMOTE IN of an optional power
amplifier
This connection is only for amplifiers and a
power antenna (aerial). Connecting any other
system may damage the unit.
 To the +12 V power terminal which is
energized when the ignition switch is set to
the accessory position
If there is no accessory position, connect to the
+12 V power (battery) terminal which is
energized at all times.
Be sure to connect the black ground (earth) lead
to the battery or distribution block ground first.
 To the +12 V power terminal which is
energized at all times
Be sure to connect the black ground (earth) lead
to the battery or distribution block ground first.
 To battery or distribution block ground
First connect the black ground (earth) lead, then
connect the yellow and red power supply leads.
When connecting to the battery directly
When the amperage rating of the fuse used on your
boat is 10 A, make the power connection to the
battery directly to avoid short circuits.
 to the positive battery terminal
 to a metal point of boat

Notes
 Despite connecting to the power supply lead of the
boat, the unit may not fully provide its performance
due to insufficient power. In this case, make the
power connection to the battery directly.
 All power wires connected to the positive battery post
should be fused within 450 mm (18 in) of the battery
post, and before they pass through any metal.
 Make sure that the boat's battery wires connected to
the boat (ground (earth) to chassis)* are of a wire
gauge at least equal to that of the main power wire
connected from the battery to the head unit.
 During full-power operation, a current of more than
15 A will run through the system. Therefore, make
sure that the wires to be connected to the +12 V and
GND terminals of this unit are at least 14-Gauge
(AWG14) or have a sectional area of more than 2mm²
( 3 / in).

Less than 450 mm (18 in)
Fuse (15 A)
If you have any questions or problems concerning
the connection, consult the dealer for details.
Subwoofer Easy Connection
You can use a subwoofer without a power amplifier
when it is connected to a rear speaker cord.
Note
Use a subwoofer with an impedance of 4 to 8 ohms,
and with adequate power handling capacities to avoid
damage.
Memory hold connection
When the yellow power supply lead is connected,
power will always be supplied to the memory
circuit even when the ignition switch is turned off.

Speaker connection

 Before connecting the speakers, turn the unit off.
 Use speakers with an impedance of 4 to 8 ohms,
and with adequate power handling capacities to
avoid damage.
