ELECTRICAL INTERCONNECTION
BEFORE CONNECTING
For the professional installation of a sound system, car audio retail stores offers appropriate wiring kits. Ensure
a sufficient profile section (refer to the table on the next page) and a suitable fuse rating and the conductivity
of the cables when you purchase your wiring kit. Clean and remove rust-streaked and oxidized areas on the
contact points of the battery and the ground connection. Make sure that all screws are fixed tight after the instal-
lation, because loose connections cause malfunctions, insufficient power supply or interferences.
+12V FULL POWER INPUT
Connect the +12V terminal with the +12V pole of the vehicle’s battery. Use a suitable cable with a suf-
ficient cross section (refer to the table on the next page).

GND FULL POWER INPUT
Connect the GND terminal with a suitable contact ground point on the vehicle’s chassis. The ground
wire must be as short as possible and must be connected to a blank metallic point at the vehicle’s
chassis. Ensure that this ground point has a stable and safe electric connection to the negative
“–”pole of the battery. Check this ground wire from the battery to the ground point if possible and
enforce it if required. Use a ground wire with a sufficient cross section (refer to the table on the next
page) and the same size like the +12V power supply wire.
LIMITED POWER INPUT (DO NOT USE)
These power connections are not used in the enclosed 20-pin wire harness (QM-FOUR-PP version).
Use only the FULL POWER INPUT to supply the amplifier with power.
