Blaupunkt MPA160us - Manual (Page 8)

The power and speaker connections for this amplifier are
explained in the summaries below and reference the numbered
call-outs above.
1.) 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 car, capable of handling high
current loads and within 3 feet (absolutely no longer than 3
feet).
TRIGGER - This allows the amp to be remotely switched
on from the radio and normally uses a dedicated “trigger”
line output. If one is not available, simply use the power
antenna line. When a +12 volt DC signal is applied it will turn
on the amplifier.
+12V - A high current line run directly to the battery is
required. This line should NOT be connected to the fuse
block of the vehicle. It MUST be fused through its own
dedicated fuse at the battery.
2.) 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
amplifier. Although another fuse is located at the battery, in
line with the battery high current line, this fuse MUST remain
in the circuit to physically protect the amplifier.
3.) SPEAKER OUTPUT CONNECTIONS - These
connections are used to connect to the loudspeakers with
the appropriate impedance. It is imperative that these lines
NOT be connected or touch the chassis of the vehicle in any
way. Also, the (+) and (-) leads are in no way inner
connected so the left channel (+) and the right channel (+)
must remain independent. In addition, the (-) leads for the
speakers CANNOT touch or be wired to the ground lead of
the amplifier; these are NOT common ground amplifiers.

Important
If wiring connections are made wrong, the
unit will not operate properly and it could be
damaged. Follow the installation
instructions carefully, or have the installation
handled by an experienced technician.
Connect directly to the vehicle battery
+ terminal with 10 gage wire (minimum)
Connect to a good chassis ground. The
ground connection should be clean,
unpainted metal to provide a good
electrical 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.
