I recently just finished the dedicated room in my basement. Turned out excellent. This ended up being an entirely different project then I had originally planned, from speakers to subs and equipment. Went with a Denon X6700H and decided instead of buying new powered subs, I went through GSG Audio and went with Marty's with Behringer NX6000 without DSP (Have a miniDSP.)
Took me about 2 months to get the project finished, and today when I hooked them up, turned on The Greatest Showman for a minute before starting to do some work with REW and calibrate everything, the first scene in the carnival tent, it popped a breaker. I have dual 20 amp circuits into the room. x6700H powers the Atmos speakers only. Monolith 7X powers everything else. Behringers are on the same 20 amp with the projector, which is the one that popped. My electrician suggest swapping one of those 20 amp into a 40 amp circuit - potentially both. But that would mean going bigger wire as well - I'm curious if that is accurate, and considering the panel is literally opposite of the back wall of my room which is in the garage, how hard is something like this to do yourself? Any suggestions for maybe a more simply solution or perhaps something else i need to consider before ripping into the panel?
