Here's my current setup.

Sony STR-DE845 receiver that has A & B speaker terminals.

Bose Acoustimass 7 speakers (8ohm) on the A terminals.

Boston Acoustics Soundware outdoor speakers (8ohm) on B terminals


I want to add a second set of the BA speakers outside, wired parallel if possible.


On the back of the receiver there is an impedance selector for 4ohm or 8ohm. Also instructions that when using A+B, set the switch to 8ohm and use 8ohm or higher speakers.


If I understand impedances right, with the second set of outdoor speakers, B will be seeing 4ohms. So should I leave the switch on 4ohms? What's my best options for properly setting this up to not hurt the amp?

You are correct that the 3rd set of speakers if wired parallel will be at 4 ohms. Question is what connections are your 3rd pair of speakers going? If your connecting them to either A or B terminals that may change your settings again. It would probably be best to set the receiver to 8 ohms to keep your power consistent throughout the setup. Make sure to wire your speakers parallel to keep the impedance as low as possible. Please let me know how it goes and get back to me. Hopefully I could be of some help.
