Wattage is fine. You’ve got a wiring / stuffing / soldering error somewhere. Post a series of well lit, in-focus photos in this thread with a description of your problem.
The document that has exactly what you are asking about is the schematic. :) The PCB is labeled with the parts locations, and the numbers on the PCB match the schematic.
As for identifying the resistors, use your multimeter set to ohms and measure them.
Also remember you can click into the photo for high resolution.
Can you bi-wire the speaker? Yes. Can you use the remaining speaker posts to do it? No. When using the ACA in bridge mode (feeding a signal through the XLR or using the white RCA and the bridge switch) the output is taken from both amplifier PCBs per speaker. Because of this, the red speaker posts, being ground, must stay empty.
The ART box you mention is a transformer based RCA to XLR converter? That should work nicely.
Again, this isn’t the place to troubleshoot. Post in this thread please.

Please post some photos of your build, particularly the inside back panel, in this thread - https://www.diyaudio.com/forums/pass-lab...
Please take some photos and post them to this thread - https://www.diyaudio.com/forums/the-diya...
Remember the PCB mounts to the top panel and all the components hang from the inside.
The amplifier circuit is inverting, so wiring it as intended and shown (with speaker red on ground) restores absolute phase.
Attach your speakers normally - red to red, black to black.

Both ways will work fine. If one was forced to choose, wire as shown the photo.

Position the tabs down towards the speaker posts, as they will not obscure the RCA’s center post once there is wire attached.
