Ground Zero GZTA 4125X-II24V Titanium Mode D'emploi page 15

TRI MODE operation output allows a subwoofer to be operated in mono mode while the main speakers are playing in stereo. Leave the
crossover switch on "Full" position.
Use 100 volt, non-polar capacitors for a high pass crossover to filter out low frequencies and Air- core or
Ferrit- ore coils with a minimum diameter of 1 mm / 0.039" for the lowpass crossover to filter out high frequencies.
The capacitor and inductor values as written in the below table. The front and rear channels of this amplifier get this capability. Only the
rear left and right channels are shown on the following pictures.
