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 speakers.
Use with full-range speakers.
• HPF –(high pass filter) blocks very
low tones from the speakers. 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 installa-
tion 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
amplifier levels are matched.
