less sensitive your ear will be to the
exact position of midbass frequencies.
The best system imaging is usually
achieved when the major portion of the
musical spectrum is handled by the full-
range system and the midbass drivers
only reproduce the frequency range
below 200-250Hz. This makes the
exact location of midbass speakers less
critical than the mid and high frequency
components in the system.

2.

The best center image will be achieved
when the distance from the left speaker
to your left ear is as equal as possible
to the distance from the right speaker
to your right ear. This is most easily
achieved by placing the 600GTi as far
forward as you can.

3.

The best system integration is achieved
when the 600GTi is mounted close to
the midrange. Installing the midrange
close to the 600GTi helps smooth the
transition from midbass to midrange at
the crossover point.

4.

You will get the best frequency
response when the path from the
speakers to your ear is unobstructed.

5.

Because of the high acoustic energy
capability of the 600GTi, they must be
securely mounted in a rigid panel which
is free from resonances, rattles and air
leakage.

6.

Due to the low frequencies reproduced
by the 600GTi, an enclosure will
enhance performance when it is
possible to accommodate one in the
available space. Use the Thiele-Small
specifications to design a sealed or
vented enclosure using standard
formulas. Thiele-Small specifications
are listed in the specifications section of
this manual.

•

Be careful not to cut or drill into fuel
tanks, fuel lines, brake or hydraulic
lines, vacuum lines or electrical wiring
when working on your vehicle. Inspect
behind panels before you cut or drill.

•

Be sure to check for clearance of
window, cranks and linkages when
mounting speakers in door panels.

•

Do not use the speakers unmounted.
Failure to securely mount this product
could result in damage or injury,
particularly in the event of an accident.

•

Although the materials used on the
600GTi are inherently water resistant,
do not mount the speakers where they
will get wet.

•

Always disconnect the ground wire
from the battery before doing any work
on the vehicle.

Pick a mounting location after reading

the recommendations in the Component
Placement section of this manual.
