Speaker Impedance
by criffus » Sun Jan 27, 2013 12:25 am
My life will be unsettled until I know the impedance on the original equipment cabin speaker for a Comanche! (ohms)
Anyone happen to possess this bit of obscure knowledge?
(The one I pulled out of my overhead has no markings to that effect on it...)
Thanks!!

Prob'ly right Zach. That's my guess...
I was just curious.
My PS Eng PMA7000B wants a 4-ohm'r by the spec sheet.
