Adjust the crossover to accommodate your
chosen installation method.
Use LPF and HPF to adjust from
50 to 250Hz.
When using your Jensen amplifier
to run a subwoofer and two full-
range speakers (known as Tri-
mode or three channel operation)
you will need to purchase separate
high and low pass crossovers from
your local retailer. A pair of high
pass crossovers for your full range speakers
and a low pass filter for the subwoofer. This
will allow the amplifier to work properly when
installing it in Tri-mode. Failure to install
these filters may damage your amplifier and/
or your speakers.
• LPF–(low pass filter) only bass
tones go to speakers. Use with
woofers or subwoofer.
• FULL–all tones go to speak-
ers. Use with full-range speak-
ers.
• HPF–(high pass filter) blocks
very low tones from the speak-
ers. Use with 6" or smaller
speakers.

Input Level Control
The input level control matches the
output of your radio to the input of
the amplifier. After the installation
is complete, make sure the input
level control on the amp is turned
down all the way (counterclockwise or all the
way to the left). Play a tape or CD (make sure
bass and treble settings or EQ are flat too)
and turn the volume up slowly until you just
start to hear distortion. Now back the volume
down just a bit. On the amp, slowly turn up
the input level control (clockwise or to the
right) until you just start to hear distortion and
back it down a bit. Now your radio and ampli-
fier levels are matched.
