whenused with normal, fullrange systems, setthese switches to “FULL.”
If you wish to use the internal crossovers to power a driver of specific
frequency range, use the “LOWPASS” or “HIGHPASS” settings.
usethese controls to match theoutputs of your head unit tothe amplifier.
Starting with your head unit set at about the 2 o’clock position, increase
theamp level controlsuntil distortion beginsto occur, andreduce slightly
from this point.
when one or both of the crossover selector switches is in “low pass”
mode, one can set the upper frequency limit for audio program sent to
the speakers.
whenthe one orboth ofcrossover selector switchis in “highpass” mode,
one can set the lower frequency limit for audio program sent to the
speakers.
this control permits adjustment of the bass level up to an increase of
approximately 18 dB in either or both pairs of channels.
this amp features gold-plated RCA input jacks for high impedance input.
Use these with car stereo output which uses RCA-type connector cables.
if your car stereo lacks RCA-type output jacks, you may connect speaker
output leads to these input connectors.

the fuse protects the amplifier and your car’s electrical system from short
circuit conditions.

to the amplifier.
these terminals are 14K gold plated to guarantee high conductivity and
minimum signal loss.
