Ampli

General

Headroom is needed. At least 2x the power rms of the driver. Big question, one big machine or multiple lil ones ?

Modes

Great vid

Stereo mode

2 channels, working separately, L / R.

Parallel mode

One source to two speakers. Mono signal. I don’t know what is the point of this (no power advantage I think), it’s a question of phase and overall tuning I thinks, to check.

Bridged mono

Connect the speaker between the two positives.
Double the voltage, so four times the power. Basically it’s linking the two channels into a big one.
