Insignia NS-A1000 Car Stereo Amplifier Connecting the remote turn-on The remote turn-on is typically wired to the power antenna output of your car stereo. With this connection, the amplifier is turned on automatically when the vehicle's stereo is turned on. Note If your car stereo does not have an active +12 volt lead when it is turned on, you can either install an auxiliary switch, or you can tap into an ignition lead. However, if you choose the ignition option, your amplifier will turn on every time you start your car. Wiring and connecting the inputs Wire routing is critical for noise-free performance. For satisfactory input wiring, observe the following: • Always use high-quality RCA-type shielded cables. • Always use the shortest length possible. If the cable is too long, make an S-type loop (not a coiled loop) in the center of the cable to take up any excess. • Never cut or splice the shielded cable. • Never route any amplifier input cables near to, or parallel with, speaker outputs, high-energy ignition wires, or computer-controlled ignition circuit units (computer units may be found behind or under the dash panel in late model cars). Connecting high-level inputs Caution For floating ground head units, connect the positive (+) speaker wires only. Do not connect the negative (-) speaker wires. For common ground head units, connect both the positive (+) and negative (-) speaker wires. Always connect the "signal ground wire" to chassis ground when using the high-level inputs. Note Do not connect high-level input wires if you are using the low-level input RCA jacks. 8 www.insignia-products.com

Connecting the remote turn-on
The remote turn-on is typically wired to the power antenna output of
your car stereo. With this connection, the amplifier is turned on
automatically when the vehicle’s stereo is turned on.
Wiring and connecting the inputs
Wire routing is critical for noise-free performance. For satisfactory
input wiring, observe the following:
•
Always use high-quality RCA-type shielded cables.
•
Always use the shortest length possible. If the cable is too
long, make an S-type loop (not a coiled loop) in the center of
the cable to take up any excess.
•
Never cut or splice the shielded cable.
•
Never route any amplifier input cables near to, or parallel with,
speaker outputs, high-energy ignition wires, or
computer-controlled ignition circuit units (computer units may
be found behind or under the dash panel in late model cars).
Connecting high-level inputs
Note
If your car stereo does not have an active +12 volt lead
when it is turned on, you can either install an auxiliary
switch, or you can tap into an ignition lead. However, if you
choose the ignition option, your amplifier will turn on every
time you start your car.
Caution
For floating ground head units, connect the positive (+)
speaker wires only. Do not connect the negative (-) speaker
wires.
For common ground head units, connect both the positive
(+) and negative (-) speaker wires.
Always connect the “signal ground wire” to chassis ground
when using the high-level inputs.
Note
Do not connect high-level input wires if you are using the
low-level input RCA jacks.
