Thanks for the help
And the answer is "maybe". It depends upon the impedance rating of the speakers, how low their impedance actually drops duing use, and the capability of the receiver to operate at that impedance.
If you do what you describe, btw, you will not be able to utilize either pair of speakers individually. So, the pool speakers will always be on if your garage speakers are on, and vice versa. Of course, you could disconnect the appropriate pair if you didn't want them on. If running both pairs simultaneously is never necessary or desired, you could use a speaker witch which would allow you to connect both pairs of speakers and switch between them.
Also, are you certain your receiver doesn't have provisions for a "B" set of speakers?
