Operation and Function
Power Connections-These connections are for input power, chassis ground,
and remote turn-on. Use a minimum of 18 gauge wire for power and ground
connections. The power wire should be fused with a 1 amp fuse.
RCA Front & Rear Outputs- These RCA output jacks provide a full range
signal to your amplier.
RCA Inputs- These RCA input jacks allow for a normal left and right channel
signal input from the source unit.
RCA Sub Outputs- These RCA output jacks provide a LP signal to your
bass amplier.
AUX Input Gain Adjustment- This control matches the input level of your cpa
with the output level of the source unit connected to the Aux input. When
properly adjusted both sources (AUX and MAIN) should play at the same
volume level. The adjustments are individual with one for the left channel
and one for the right channel.
LPF Frequency Adjustment- This controls the cutoff frequency of the LPF
on the "SUB OUT" channels. The lter is variable from 50Hz to 150Hz.
Volume Control- This raises and lowers the volume on all the cpa's outputs
simultaneously.
Subwoofer Level Adjustment- This raises and lowers the level of just the
"SUB OUT" channels.
Fader Adjustment- This allows you to adjust the level between the "Front"
and "Rear" channels.
Illumination Selector- Changes illumination around controls to red or blue.
AUX Input Switch- This switch is used to select the input of the cpa. When
the button is pressed in the "AUX" input is seleced. In normal position the
main input is active.
Equalizer level Adjustment- There are seven different frequencies or bands
that can be adjusted. Each band has an available adjustment of +/-10dB.

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 rst 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 (REM)
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.
