This was a fun and challenging build!

I ordered some cheap single board amps and power supplies from AliExpress and used a DSP so each speaker (mid/tweet/sub) has their own dedicated amp and fine tune control ability for the frequency drop-offs, gain, etc.
They sound amazing!
Oh, gotcha. I don’t know the first thing about building/wiring audio, I just haven’t seen a sub with a cabinet that tall before! It looks great under the desk in your setup.
