Insignia NS-A1200 Car Amplifier
To connect the power:
1 Connect the ground wire to the vehicle's chassis. To avoid ignition
noise caused by ground loops, the amplifier must be grounded to
a clean, bare, metal surface of the vehicle's chassis.
2 Connect the +12 volt (fused) constant power cable to the battery's
positive (+) terminal.
Because of the amplifier's power requirements, this connection
should be made directly to the battery's positive (+) terminal. For
safety, install an in-line fuse holder (not included) as close to the
battery's positive (+) terminal as possible. The fuse should have
an ampere rating that does not exceed the total value of fuses in
the amplifier.
3 Connect the remote turn-on input to the power antenna output of
your car stereo. This amplifier is turned on whenever the vehicle's
stereo is turned on.
Note
Ground wire should not be more than three feet
(one meter) long.
Note
If your radio does not have a +12 volt output lead when the
radio is turned on, the REM terminal on the amplifier can be
connected to the vehicle's accessory circuit that is live when
the ignition key is on.
Warning
Thoroughly investigate the layout of your vehicle before
drilling or cutting any holes. Take extra precautions when
working near tanks, lines, hydraulic lines, and electrical
wiring. Don't mount this system so that the wire connections
are unprotected or are subject to pinching or damage from
nearby objects.
The +12 volt DC power wire must be fused at the battery
positive (+) terminal connection. Before making or breaking
power connections at this system's power terminals,
disconnect the +12V wire at the battery end.
Make sure that your stereo and other audio equipment is
turned off while connecting the input jacks and speaker
terminals of your amplifier.
If you need to replace the power fuse, replace it only with a
fuse identical to that supplied with the system. Using a fuse
of a different type or rating may result in damage to this
system, which isn't covered by the warranty.
