I have a pioneer vsx-7500s , all of sudden A B speakers and sub woofer stopped working , only rear speakers working , any suggestion how to fix it .

[@froitechtv2605]

Ok. My suggestion is obserb the speaker relay for A & B if clicking. Then if clicking that amp from A B is possible good. Next to check is A B speaker switch for possible poor contact. Repair the switch
