From the Legacy Manual:


The supplied charging bulb(included
in the package)is used when initially
charging the Cap. the charging process
is accomplished by connecting the
charging bulb in series between the
battery’s positive post and the
capacitor’s positive terminal.(plese
refer to the diagrambelow). it is very
important to follow this process to
eliminate the possibility of damaging
the cap/battery, and other audio
devices. The charging process is
complete when the voltage of the
capacitor reaches the same voltage
as your vehicle’s battery. This process
will take a matter of seconds to
complete. You can use a voltage meter
to check the voltage across your
battery and cup .when the voltages
are the same on both(cap and battery),
the cap has been fully charged. The
charging bulb actually eliminates the
need for the volt meter, when the cap
is fully charged (cap and battery have
same voltage) the bulb will go either
dim or fully out.

Can i charge my didgi cap with a batt. charger?? stupid i know but i gotta make sure im stupid before i belive it:)


You aren't stupid just need information about the capacitor!

Here is a short explanation as to how the cap works and also the link:

How the Capacitor Works
  • A capacitor is an electricity storage device; think of it as a short-term battery that can release power quickly to meet peak demands, unlike a battery that releases power in a steady stream. When the capacitor is in-line in the amplifier's electrical system, it will release electrical energy when the amplifier hits a high demand. The power released by the capacitor makes up for the shortfall in the system, so the car's electrical system isn't compromised, and the amplifier has sufficient power to drive the subwoofer effectively.

    How many volts am I supposed to read at the remote terminal, and is the light beside the display supposed to be on at all times or not? Thanks if anyone knows...


    Your voltage reading should be around 12 to 14 volts when operating correctly. Capacitor is a storage for voltage and the power is constant so I am assuming that light will be on.

    KDC-w3041 says PROTECTION when i turn it on


    Sometimes if the power is removed it requires a code to be input, to remove the protection, you will have to contact Kenwood, and ask for the code to clear it. This is an anti theft feature. Often the car dealers have these, or try an auto-electrician.. BTW your English is good.

    You hook it up in parallel with your amp. You'll see a and - on the clear plastic cover.
    Hook a wire from your amp or positive to the capacitor
    Hook another wire from your amp - or negative to the - on the capacitor.

    That's it, you're done.

    If the plastic cover is missing, or painted over, with the neon tubes at the top, and the connector/display end facing you, the right side is the left side is -.
