trying cutting the frequencies in the mid-
bass (90 to 250 Hz) and mid-range (2 to 4
kHz) spectrum. The mid-bass response is
usually a problem area due to standing
waves caused by sound resonating in the
passenger compartment. The mid-range
frequencies are most sensitive to the ear
and usually need to be brought down a

NOTE: Consult the amplifier owner’s manual
for information on setting its input sensitivity.
If adjustable, set each amplifier to accept a
signal between 1.0 and 2.0 volts (1000 and 2000
mV). This may be a minimum setting on your
amp. Don’t worry, the EQL can still drive it to
full volume. If your Amp cannot accept 2V you
may need to turn the output level down a bit.
