How do i connect 2 pairs (4 speakers) from an amplifierr 5.1 ? And will they work as sterio left and right channels ? Are they 80w each so what power on the amplifier do i need ? Thankd
Asked by: E
Bose rates these speakers to work with an amplifier or receiver putting out 10 to 100 watts per channel. These outdoor speakers can be connected to a stereo receiver, such as the Yamaha R-S202 Stereo Receiver with Bluetooth (Black), BH #YARS202BL, with two speakers hooked up in tandem to the left channel and two on the right. You may also consider using a surround sound receiver, such as the Sony STR-DH790 7.2-Channel A/V Receiver, BH #SOSTRDH790, with each a signal sent from four individual surround outputs. The receiver can then would be set to "all stereo" or "mono" setting for the best option for listening to music outdoors with four speakers.
