Man..... talk about some progress! I have absolutely nothing of interest to add, other than I think the Brembo circle logo only on the e-brake caliper would look better for some reason. Unsure why, just stood out to the non-builder in me.
I've kicked around sub idea for mine as well, I think may have room under my dash to potentially fit a class-d 5-channel since the Kappas really shine with more power from my experience (albeit 20yrs ago), plus would need a sub amp. I was told about vehicle "micro amps" are even smaller, but haven't looked into them (if they are a new thing). Never tested any amp under the dash, just guessing.
