I wired my house for sound throughout. Each room has four speakers, 2 channels, and home runs to a sound closet. I have a Cress 70.7-volt stereo amp and 34 Sony 3-ohm cube speakers. I believe I need to find some step-down transformers but everything is geared for 2-4-8-16 ohm. Any idears? I am new to this so much of the info is Greek to me right now. Thanks.
