Actually the 150 and 180 run together poses no real problems as far as loudness/sensitivity goes. The 150 is barely a 1/2 db quieter than the 180 when I played with the 2 of them. Whether or not the ~2-3 ohm total resistance causes a problem is another story.
Wasn't there something about running them together that you didn't like? I don't recall what it was exactly, other than you didn't really recommend it.
When ya live "Up yonder", ya get confused easily eh .
The only reasonable argument for owning a gun is to protect yourself from the police.
