The 
 amplifiers incorporate an on-board staggered 
 crossover, with RCA outputs to drive an external amplifier. No
external electronic crossover is necessary. The high and low pass
portions of the crossover can be set independently of one another.
To engage the High Pass filter, set the left 
crossover 
switch on the
top of the amplifier to 
 X-OVER”, and use the frequency adjust-
ment knob marked “H.P. X-OVER”. To engage the Low Pass filter,
set the left crossover switch to either “SUB SONIC” or “HAWKINS
BASS CONTROL” (see pages 1 O-1 1 for more details), and set the
right crossover switch “L.P. X-OVER” to the “IN” position.
In many car audio installations, there is a tendency  for a 
boom.” Because of their interior dimensions, most cars will 
nate or ring at these 
 frequencies. If we design the system
so there is reduced output in this region, the final response is very
smooth and natural sounding. The high pass 
 is 
dently variable from 70 to 160  Hz at 12 dB/Octave, and the low pass
crossover is independently variable from 55 to 220 Hz at 24 
tave.
For initial crossover setup, try setting the low pass filter 
to 
approxi-
mately 60 Hz, and the high pass filter to approximately 100  Hz.
Change the crossover points to accommodate good mixture of
frequency response, power handling, and personal preference.
