Installation with PP-ISO cable
To simplify installation to an OEM or aftermarket
radio the UP 7DSP can also be connected using
the optional PP-ISO cable (2.2 m version, art. no.
H424922). This cable allows to feed the amplifier
with the highlevel signals from the radio and return
the amplified output signals back to the loudspeak
-
ers. No factory wires or plugs need to be cut by us-
ing this connection method.
ATTENTION: Never use the PP-ISO cable for the
power supply of the UP 7DSP!
You may risk a severe damage of other electronic
components inside your car or even a cable fire!
Read in the following the steps how to connect the
amplifier to the head unit / car radio via PP-ISO ca
