Thanks a lot guys for enlightening me. 98% of my knowledge about electronics comes from watching EEVblog, BigClive, and a bit Mr.Carlson.
The 10M resistors and the ground connection next to the transistors is only there, because i could not figure out how to place a single supply with +48 on the top and -48 on the bottom in Qucs.
Soundquality is actually very important. we already have a speaker( a dumpsterdive ) that can go loud and if you dont know the tracks it sounds ok , but whenever i play sth. that i enjoyed at home i am dissapointed. on friday i found a nice suitable speaker kit but could not find an amplifier kit with 50-100 Watts, that i can trust. but after i wrote that sentence i checked again and find a lot.
I didnĀ“t know the data sheets include reference designs and partslists for everything i need

. so i thought an oldschool design with discreet transistors would be easiest.
but texas instruments has enough info that i will leave out the passive crossover and use an active one for almost the same price.
but thanks again for your input. without you i probably would have screwed around with my idea for another 2 or 3 days.
