I have some 6x9 aerial tower speakers and they read 4 ohms on the back and the in the manual. When i ohm them out through the my tower speaker wires they ohm out a 3.3 ohms. I wired them up to my four channel sony amp( specs below) and they didn't work. So i put them on the bridged terminal they worked for about 10 mins of playing hard on them and i blew a fuse.
On the other side of the amp i have 2 6.5" polk dbs 4 ohms each on a channel by themselves and they were doing fine.
My questions is why would these speakers be reading 3.3 ohms? And should this sony amp be able to push these four speakers?
