I'm new to this forum so bear with me guys. I have a panasonic audio/video receiver rated at 100W x 5 @ 6 ohms. The speakers i have are sony towers w/ 2 - 6.5" , 1 - 3.x , and a .75" speakers. The speakers are rated at 8 ohms. I know since they are working at 8 ohms the speakers aren't seeing the full 100W. I was wondering if I could rewire the speakers for a 4 ohm impedance to get more power to them without any harmful consequences? I know the receiver will have to work harder and may overheat or will 2 ohms make that much of a difference? If i wire the speakers for 4 ohms, how much power will the speakers see then instead of the 100W rms? Any suggestions are greatly appreciated.
