I've removed the mvs pcb from my cabinet and am attaching a laptop through a J-Pac (got a bunch of thread all around the board asking for help with the different aspects :p).
Now everything is slowly coming together but I have 2 main problems left:
1. I disconnected the power supply and connected the monitor (hantarex polo) directly to the ac mains (as nothing else needs power since it will be all going through the laptop. However this means that all the ground wires in the cabinet now lead to an inactive power supply which is not turned on (or even connected). Is this a problem? How can I solve it?
2. My laptop has an internal 4ohm stereo speaker. If I disconnect this (it has 2 wires going in, one red and one black) and connect its wires to the speaker+/speaker- screw connectors on the J-Pac will that give me sound out of the cabinet speaker? The speaker on the cabinet is 8ohm and mono however.
