Rem Out: Connect this terminal to the remote turn-on terminals of all amplifiers in the system. The
output is +12V DC, 1A.
IMPORTANT: The MS-8 MUST control the turn-on signal of all the other amplifiers
that follow the MS-8 in the signal path.
If your system includes a factory-installed outboard amplifier, the turn-on signal
may be available at the amplifier. If your factory amplifier has a turn-on wire, cut it
and connect the head-unit side of the wire to the MS-8’s Rem In terminal and the
amplifier side of the wire to the MS-8’s Rem Out terminal.
This arrangement will allow the factory stereo to turn the MS-8 on whenever the
stereo is turned on and will allow the MS-8 to turn the factory amplifier on and off.
It will also help to eliminate audible clicks and pops when the system turns on and
off.
2. +12V: Connect this terminal to the vehicle battery’s positive (+) terminal. Insert a 25A fuse in series on
the +12V wire no further than 18 inches (46cm) from the battery terminal.
IMPORTANT: Use at least 12-gauge wire for this connection.
