Setting the high-pass filter

If a subwoofer is connected to your car radio,
you can use a high-pass filter (HP-F) to sup-
press the output of lower frequencies through
the internal final amplifier and an external pre-
amplifier that may be connected. This filter
has five adjustment levels. The settings de-
pend on the unit installed in your car. Experi-
ment to find your ideal setting.
