Make sure you are using a main fuse protection for the +12V-
power input of the amplifier within max. 30 cm of the car
battery and power cables with an amperage adequate cross-section
and main fuse (for details see section E: „Connecting") .

The GROUND/GND cable (-12V) should have the same cross-
section as the +12V power cable. Make sure to get a good
chassis ground contact, because poor ground contacts are the cause
for most power problems with car audio installations .

Make sure no power, signal or speaker lines are shorting to chassis
ground by using rubber grommets wherever a cable has to
pass through any metal part of the vehicle.
Important: Before any wiring, always remove the -12V terminal of
the battery to prevent short-circuiting. The last lead to be con-
nected in every installation is always the -12 Volt terminal of the
battery. Connect this lead only after having completed and checked
all other connections .
