    I have a Yamaha Av amp AX750 SE, but i think my question applys to most AV amps.

    On the front speaker binding posts you have an 'A' and a 'B' option. Are the 'B' binding posts just an extension of the 'A' binding posts?

    If that is the case, then i am assuming connecting speakers to the 'B' binding posts as well as 'A' has then effect of parallel wiring and changes the resistance placed upon the amp accordingly.

    Is there any damage in running these AV amps at 4ohms?

    Thanks

    Andy

    You're exactly right in your thinking apart from if you connect a single speaker to both A & B terminals in a biwiring fashion then the amplifier still only "sees" the 8ohm load.

    Connecting a different speaker to each output and running them both will create the 4ohm load you describe which I wouldn't recommend for loud or prolonged use. :)
