I bought a brand new crate g160 combo back in 1990. Well I started my first hard rock band back then my new crate was working great. With only one 12 inch speaker in it I wanted a 4x12 cab. It has a ext cab out on it. I found a used Jackson 4x12 cab at guitar center I bought it got home and plug it in I unplugged the 12 in my amp and used the cab only sounded great. I didn't know anything about ohms back then and I couldn't figure why my volume level dropped so much. My amp was 4 ohms and the cab was 16 ohms. Well that was the problem. I found a guy at this little guitar store and told him about was going on  and he said running 4 ohms into 16 is no good that's why I lost volume he ask me if I new if the speakers in the cab were 16 ohms I didn't know so I checked them and they were. I took the cab to him and he rewired the speakers down to 4 ohms got it back home plugged it in holy crap couldn't  believe the difference in volume. So ohms is really important. Sorry for the long story. And if I remember right I burnt the transformer out 2 times using 4 into 16 and he said that's what burned the transformer out after rewiring the speakers never had a problem again.
