I have an audio PA which rated at 4ohms 22W in bridge tied load or 2ohms in stereo mode. What will possibly happen to the audio PA when I connects a 3.2ohms speaker parallel with 16ohms speaker in bridge configuration? Which in my own understand that the resultant impedance is 2.7ohms can eventually burn the pa. Am i right? I am also looking for an analog cmos switch which I able to enable/disable the 16ohms speaker. The switch must able withstand max 1A and 14V peak value and Ron must be ultra low <1ohms. Has anybody come across this component? Please tell me. Thank you in advance.
