Don't no how to hook it up ...

Instructions
Hook up an RCA patch cable
between the output of your car's
stereo receiver and the graphic
equalizer's RCA inputs. Use
stereo cables with male RCA
connectors.
Connect the equalizer's outputs
to the RCA inputs of your
amplifiers. How many cables you
need will depend upon the
number of amps in the system. In
most cases, you'll need two to
three to connect the equalizer to
the inputs of your amplifiers.
Hook up the equalizer to 12-volt
power. Use the same power
connections you used to connect
your amplifiers and receiver. The
equalizer's yellow wire should be
connected to a constant power
source, one that is not switched
off with the ignition, and the red
wire (not always present) to a
switched 12-volt power source.
Splice the wires by stripping the
insulation off the end of each
wire and then soldering or
crimping them together.
Connect the equalizer's blue
"turn-on" lead to the receiver's
blue wire. This turns the
equalizer on when the receiver is
powered up.
