y-cable on VEX Speakers

@Vexly and anyone else reading the official q&a thread, regarding y-cabling 2 speakers:

A warning that you might damage your cortex:

When you parallel wire speakers (like a Y-cable would do), you will cut the impedance in half. For example, two 8-ohm speakers in parallel gives 4-ohms. (Check any basic electronics book for the “resistors in parallel” formula). Cutting the impedance in half will double the amperage on the Cortex’s audio output circuit, which may cause some unknown result (check that same book for Ohm’s law).
