Can some one please tell me the best way to add 2 outdoor speakers (to my patio) from my existing Home Theater System (Sony HT-DDW700) 5.1 surrond sound. My receiver has no a/b switch and the back ony has speaker input for the 6 speakers. Is a speaker switch a good option? And also could I have my inside speakers off and outside on? Any help will be greatly appreciated. Thanks.
