say it comes with all 3 trim colors

how do I hook up 4 8 ohm speakers?

Two sets of two speakers. A-B and C-DConnect A-B in parallel; Connect C-D in parallel. Each set will therefore be 4 ohms per set. Then connect each set in Series and that will end up as being 8 Ohms

Please explain if the slider itself can be ivory, along with the plate or if the slider control is one color and the plates changeable?

Hello, the plates, screws and slider pieces are the different colors.

Will this match the impedance for 3 speakers?

Why would alejandro say you can only have 3 speakers. The description clearly states "up to 8 pairs of 8ohm speakers" .
