fenlan How to use the splitter board:
First as per above (Treble, Low, Input), to speaker, seal air space, begin to hear music while optimize.
Normally we use jumper A and let B idle. For jumper C and D: we need to hear the actual effect of treble. A general formula is: A+D = better ; A+C = clear Treble and ; A+CD = clear Treble and (the overall effect inclined towards Treble); +CD = more mediant frequency. When effect is unnecessarily high, remove cap A. Please optimize the sound is best, and then fix the board with your speaker unit.
