For the best performance and
system reliability, you should select an
amplifier with an output rating greater than
the maximum power likely to be used to
generate the desired volume levels. If you
want your system “Loud + Clear,” we
suggest that you step up to a JBL power
amplifier which has an RMS power rating
equal to, but not exceeding, the
amplifier with an output rating greater than

In Case of Difficulty
The most common difficulties are
noise, distortion, and intermittent
connections.
connections.
System noise is usually not the fault of
the 600GTi. Hiss or "alternator whine" is
most often the result of faulty grounding of
the system electronics or improper setting
of amplifier level controls. An exception to
this is if the passive crossover networks
are mounted near a source of radiated
noise, the network may pick-up this noise
with sufficient power to drive the 600GTi.
For this reason, be careful not to mount
any passive crossovers near wires
carrying high currents such as battery
cables or wires leading to ammeters or
tachometers.

Distortion is usually the result of
overdriving one or more components in
the system. The problem is most likely
insufficient amplifier power, or improper
setting of gain controls. Refer to the
