JBL 400GTi Car Speaker User Manual


 
Note: The metal grille is designed so
that it can be covered with grille cloth if
desired. Simply remove the metal grille
from the grille frame as shown in Figure C.
Then use spray adhesive to glue and wrap
the grille cloth to the metal grille. Push the
metal grille with cloth back in the plastic
trim ring. For even better interior matching
it is also possible to use plastic compatible
paint to match the grille frame to the
vehicle’s interior.
Logo Orientation on Grille
The orientation of the logo on the
grille relative to the grille frame can be
adjusted. Simply remove the metal grille
and reassemble the metal grille to the
grille frame utilizing a different tab slot.
Wiring
Use 2-conductor stranded type,
insulated wire to connect the 400 and
500GTi to its crossover, and the crossover
to the amplifier. A minimum wire gauge of
18AWG is recommended, with larger size
wire suggested for runs longer than 10 feet.
The polarity (the positive / negative
orientation of the connections) for every
speaker-to-amplifier connection must be
consistent from left to right channel to
assure proper imaging and optimum
frequency response. This does not mean
