close but not entirely correct…first off, I ground EVERYTHING separate. i do not share a common grounding point. and secondly… if the cap has a power INPUT post and a power OUTPUT post and ONLY the monoblock amp is hooked to the output post, how do you deduce that it is supplying power elsewhere? it doesn’t. the ONLY time the capacitor discharges is when the monoblock requires more electricity, OR if someone were to inadvertently ground it with say…a screwdriver… (which is fun… trust me…sarcasm). the electricity cant magically jump wires to power another amp if that other amp isnt hooked to the cap OUTPUT terminal.
