Installation
The basics of car audio installation apply to both the DSP-Z8 IV II and the ADSP-Z8 IV-8.
Getting Started
: The very first thing you want to do when installing any electronic device into
the car is to disconnect the negative battery terminal to prevent any accidents (dropping a
live hot wire on a component that has been mounted to the metal of the car can destroy
that expensive piece of gear you just bought).
Choose a secure mounting location for the DSP-Z8 IV II unit. You need to avoid sources of
heat and moisture and provide adequate ventilation for cooling. Check around and under
the location for any wires, hoses, etc. before drilling holes. Also avoid mounting the unit too
close to any main electronic control modules as they can be bad noise sources. Plan out the
power and signal wiring to the DSP, and then out to the amps (or speakers if you have the
ADSP-Z8 IV-8). The Dash Remote wire needs to be run to the mounting location also, as well
as any optical or auxiliary input cables. Depending on your installation, you will probably
want to run all the wires and cables to the unit’s mounting location before mounting. Once
the area is prepared, mount the unit securely using the proper hardware.
Power : Main +12V power to the amp must come directly from the B terminal and
should be 4-Gage or larger depending on the length needed. The yellow B+ power for the
DSP should come from a power source that is constant hot. Whether it is a processor or a
processor/amplifier, the single biggest cause of system noise is a weak or insufficient ground
connection. This is especially critical for the amplifier as a weak ground will also prevent the
amplifier from reaching its full power. The ground connection should be directly the vehicle
chassis/frame (or a heavy chassis panel directly connected to the frame). The gage of the
ground wire should be at least as large as the gage of battery power wire.
Physical Connections
: The two units of the Z8IV II series share most of the same processor
connections but with slightly different layouts. Of course, the ADSP-Z8 IV-8 requires much
more input power and has speaker outputs.
