Making of Power supply/bank 65-0-65 35-40amp for class D/ab/a/b. 

It depends upon capacitor amplifier board and tranformer. App jo board use kar rahe ho kitne time ke liye use kar rahe ho tranformer ka amp kya hai sab depend karta hai. max 2 board use kar sakte hai. mai class d or ab 2 board use kar leta hu but normal use ke liye not for dj setup.
