Alpine KTP-190U - Wiring Connections and Switch Settings; Audio Connections; Switch Functions

CONNECTIONS {Fig. 3)
Before making connections, be sure to turn the power off to
all
audio components. Connect the
red battery lead from the amp directly to the positive(+) terminal of the vehicle's
battery. Do not
connect this lead to the fuse block.
~CAUTION

Caution
on
connection
terminals/parts
•
Keep
electrically
conductive objects away from the unit's terminals/parts (power terminals,
fuses, speaker output terminals, RCA connectors, etc.). Doing so prevents a possible short
circuit and damage to the unit.
To prevent external
noise
from
entering
the
audio
system.
•
Locate the unit and route the leads at least
10
em
(3-15/16•) away from the car harness.
•
Keep the battery power leads as far away from other leads as possible.
•
Connect the ground lead securely to a bare metal spot
(remove any paint
or
grease if necessary) of the car chassis.
•
Your Alpine dealer knows best about noise prevention
measures so consult your dealer for further information.

Do
not connect speaker leads together
or
to chassis ground.

Ground
Lead
(Black)
Connect this lead securely to a
clean,
bare metal spot on
the
vehicle's
chassis. Verify this point to be a true ground by checking for continuity between
that point and the negative(-) terminal of the vehicle's
battery. Ground
all
your audio
components to the same point on the chassis to prevent ground loops.

Battery Lead
(Yellow)
Connect battery lead directly to BATT +
Be sure to add a 10A fuse (sold separately) as close
as possible
to the battery's (+)terminal.
Note:
This unit does not have a remote turn-on lead. The amplifier turns on/
off
automatically by using a
built-in signal sensing circuit.
