Installation Instructions
Careful thought and planning is a must in installing a mobile audio
system. Extra consideration is always recommended when
routing the signal cables to guard against injecting noise into the
system. NEVER mount any piece of ZAPCO equipment in the
engine compartment. Avoid routing signal and power cables
together in one bundle; isolate these lines on opposite sides of the
vehicle if at all possible.
Keep the above thoughts firmly in mind when determing a suitable
mounting location for the PX Main. It may be mounted under-
dash using the supplied bracket or in-dash using the four
countersunk mounting holes in the front panel. If mounting in-
dash, allow sufficient slack in the cabling to and from the unit as
access to the back panel controls may be necessary in fine tuning
the crossover point or output levels.
The PSi can be mounted virtually anywhere within the vehicle that
is free from moisture. Its compact design, plug-in barrier strip and
power connections enable the installer to mount the unit in
potentially hard to reach locations. While the stock, fifteen foot
cable length should be taken into consideration when determing
the mounting location, custom length cables can be ordered from
A.R.P.A. of America Corp.
The plug-in barrier strip is used to terminate all necessary power
and turn-on connections. The connector is polarized and will only
plug into the unit one way. Care must be taken to insure that each
connection terminates to the proper position on the plug! Note
that when looking at the screw side of the plug-in module all
connections are reverse of the label on the top of the unit.
BEFORE INSTALLING ANY PIECES OF EQUIPMENT: LIFT
THE NEGATIVE (GROUND) BATTERY LEAD.
