Crossover (X-OVER)
Level
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 amplifier
levels are matched.

Tri-mode/Three channel operation
An amplifier is usually configured for tri-mode
operation when you want to use one amplifier
to drive a pair of front speakers and
subwoofer(s). In other words, when you want
to drive a complete system with one amp.
Your Jensen amplifier is capable of tri-mode
operation.
