amplifier. Use cable grommets when pass-
ing cables through holes with sharp edges.
Use loudspeakers with an impedance of
Ω
2 to 4 (see table or installation drawing).
Observe the max. power handling specifi-
cations (music output). Do not connect the
loudspeakers to ground; only use the termi-
nals provided. The cross-section of the pos-
itive and negative cable must be at least
6 mm 2 .
GTA 4 Spezial amplifier
The amplifier is suitable for connection to car
radios with Cinch connector. Use the Blau-
punkt ISO Cinch adapter to connect the
amplifier to car radios with ISO connec-
tor (7 607 893 093/ 7 607 855 094).

Positive/negative connection
We recommend a cable cross-section of not
2
less than 6 mm . Run a standard commer-
cial positive cable to the battery and con-
nect to the fuse holder. Use cable grommets
when passing cables through holes with
sharp edges. Bolt a standard commercial
negative cable to a ground point free of in-
duced noise (car body bolt, body panel) -
not to the negative battery pole. Clean the
contact surface of the ground point down to
bare metal and coat with antiseize graphite
petroleum.
Integral fuses
The integral fuses within the amplifier pro-
tect the final stage and the entire electrical
system in the event of a fault. Never bridge
fuses or replace fuses with a higher current
rating.
