Blaupunkt PCA 450 - Manual (Page 8)

POWER CONNECTIONS:
GROUND - This is the high current ground connection to the chassis of the
car. It should be fastened to a clean ground connection in the vehicle, capable
of handling high current loads. This wire should be no longer than 3 feet (1
meter)
+12v - A high current line run direct from the batter is highly recommended to
insure adequate current and voltage. This line MUST be run through a
dedicated fuse of some kind and this fuse should be located immediately next
to the power source. This in-line fuse is used to protect the vehicle should a
short to chassis occur.
TRIGGER - This line tells the amp to turn on and is remotely switched from
the radio which normally provides an amp “trigger” output. This line is
required to go “high” (+12V) to turn on the amp. If this line is not available, use
the power antenna line trigger which is normally available in most radios.
FUSE - This fuse is only for catastrophic situations should the amplifier begin to
self-destruct or incur installation situations where gross amounts of current are
being required from the amp beyond its design limits. Although another fuse
should be installed inline with the high power line at the battery, this amplifier
mounted fuse MUST remain in the circuit to protect the amplifier.
SPEAKER OUTPUTS - The amplifier is connected to appropriate impedance
speakers via these leads. It is IMPERATIVE that these leads NOT be
connected or touch the vehicle chassis in any way or the amplifier will be
damaged. The (+) and (-) leads of the amp are in no way inter-connected to
one another. Also, NONE of the leads can touch each other, touch ground, or
touch +12V or damage may occur to the amp or vehicle.

Connect to a good chassis ground. The
ground connection should be clean,

connection.
Connect the radio power antenna lead from
the receiver to the amplifier terminal.
This turns the amplifier on whenever the
receiver is turned on.
