18.
Replace 20amp fuse under hood.
19. When amp turns on, LED will display
red
during diagnostic mode,
and
then
green, signaling amp is
on
and functioning. Amp will only turn
on
when radio
is
on.
20.
Adjust gain and crossover.
Setting Gain
Turn gain knob
on
ThunderForm pre-amp
to
minimum, counter clockwise. Play
a favorite tape or compact disc that contains consistent music and bass. Turn
the source unit to maximum listening level.
You
may want to turn down the
bass slightly
on
the source unit. You should know that some source units will
produce distortion or "clip" before the unit reaches maximum volume. Reduce
volume to the loudest listening level before distortion. Turn the gain knob
on
the
ThunderForm pre-amp clockwise until the speaker starts to distort
and
reduce
gain to loudest listening level before distortion.
Optional- The
EBC,
or Electronic Bass Control, allows a remote bass control
to
be adjusted from the driver's seat.
Setting Crossover
You should set the crossover to your own personal listening taste. The cross-
over is adjustable to any frequency between 50Hz (counterclockwise)
to
150Hz
(clockwise).
As
a guideline, the goal is to create the illusion of bass
up
front. The
higher the crossover point the more "audibly visible" your sub
is
going to
be.
Take
your time and really listen to your system, grab a soda and a few of your favorite
tunes and have fun.
TROUBLESHOOTING TIPS IF AMP DOES NOT TURN ON

at
battery
and
that fuse is installed
