Perfect for a pair of S5's or greater. Maybe 4 4" coiled subs at 4K rms ea. I like extra power on tap myself, the ability to take the sub to the MAX in along with an enclosure designed to do so. 26K?... lets talk real world.
Experience tells me this'll put MAYBE 18k into a sub system and if the subs are able that's more than enough for even demos. You'll need some electrical to be sure and what nobody talks about... deep pockets. Just supporting this amp will cost $ to do it right.
I do LOVE big power problems but prefer efficiency on big power myself... I bashed my own head against that 3 laws wall for multiple decades and now... they say AI is going to replace my hard earned experience?
Good Luck Charlie...
I just try to help if I can
