Installation Guidelines
INSTALLATION PRECAUTIONS
• Always mount the unit in a fashion so that it can be easily accessible for making
adjustments.
• Avoid mounting the unit to subwoofer enclosures or high vibration areas.
• Do not cover the unit with carpet or any other material.
• Do not mount the unit in the engine compartment or anywhere that it will be subject
to high temperatures, (ie, direct sunlight or heater) moisture, dust or dirt.
•Use rubber or plastic grommets to protect wires when routing them through metal.
•Always keep signal wires away from high current power wires.
•The ground connection should always be the first connection made.
WIRING INSTRUCTIONS
Ground Connection (GND)
The main ground connection should be made between the Gnd terminal on the unit
and a metal part of the vehicle close to the mounting location. This wire needs to be
as short as possible to minimize the possibility of induced noise. You should use 18
gauge wire or larger for the ground connection. The metal point on the vehicle where
the ground connection is made needs to have all paint removed and be scuffed down
to the bare metal. The ground wire should have a ring terminal soldered to it and be
bolted directly to the vehicle with the use of a star washer. Do not ground the unit near
existing (factory) ground points. These areas generally have multiple devices ground-
ed to them and can cause induced noise.
Power Connection (+12V)
The main power connection should be made at the battery. This will ensure that the
unit receives the best possible connection to minimize noise. There must be an inline
fuse (1 amp) placed in series with the unit. The fuse should be within 18" of the bat-
tery. You should use 18 gauge wire or larger for the power connection. The power
wire should have a ring terminal soldered to it and be bolted to the vehicles battery. Do
not install the fuse in the holder until all the systems connections have been made.
Remote In
This Caché unit is turned on by applying +12 VDC to the remote turn-on terminal. This
terminal should be connected to the remote lead from the car stereo. This remote
lead from the source unit will trigger a +12V output only when the car stereo is turned
on. If the source unit does not provide a remote turn on you can use the accessory
terminal in the cars fuse block. This will however turn the unit on and off with the key,
regardless of whether the source unit is on or off.
Remote Out
This Caché unit is equipped with a signal sensing circuit that can detect a signal on
its input and provide a +12V output signal to turn on an aftermarket amplifier. Connect
this to the remote terminal on an aftermarket amplifier.
