Size amp needed to drive 6 klipsch 8 ohm speakers
I have 12 newly in home installed klipsch speakers in 6 areas ( 2 per). A speaker router chooses what pairs on want to be on. I have a Harman kardon HK 3250 receiver that I found out was 40 watts channel. The speakers are 8 ohm 75 watts cont/ 300 peak rated. I ran the speakers sometimes up to 3 pair at time for a while , now the receiver trips out when trying to increase the volume very much at all. The receiver has a pre out connection.? Can I still use it or is it cooked? And what size amp do I need to drive those speakers ? Should I increase the channel output and get rid of the selector unit?
