Sounds like some serious bridging going on! I would think that would sound pretty good, lots of headroom and low distortion quality signal going to the speakers. I plan on doing something similar but with no trunk sub. 200W to each 8" ssmb unerseat, 150W to each morel mid/tweeter combo and 160W to my xtant center coaxial.
I got a kick out of your typos, 'underwear woofers' and front door 'kids'.
