In 2017 my dad bought a trio of 1099 for our theater upgrade from BIC Venturis and has sat in their boxes until last year, the summer before my senior year in high school where I started, and I finished one of the speakers. I completed the second speaker during the spring and started to work on the final speaker and I hope to finish this project before I start college.
The final 1099 board is where issues arise as the entire crossover board works perfectly fine for the tweeters and woofers. The mid drivers do not play any audio when paired together, but when one is connected the audio comes through at a very faint low volume in comparison to what the other two completed speakers put out when playing audio.

I am not sure if the issue is simply a bad wire connection between components or if it is something to do with a bad component that has been damaged or is faulty. I plan on replacing a few of the wires, checking the board with a multimeter, finally resoldering the entire board with potentially new electronics if needed.
Any other tips to troubleshooting crossovers would be greatly appreciated along with what your thoughts are on what the potential issue may be. I have also put in a few pictures below of progress and the entire theater.

The final plan once this is completed is to build a wall or a curtain that surrounds the area, put the speakers behind a sound transparent screen and put sound proofing on the walls.
