Thanks, I guess it just starts to suck the amperage at 1ohm eh?  I just know of one for sale and am thinking maybe I should scoop it up.  I really don't want to buy something I will regret though.  I like headroom in my systems and worry sometimes. So if you wanted an "SQ-L" sub that you'd put in a sealed box in the trunk of a sedan, trying to save some room for strollers, etc. what would you pick?  Since this is a discussion forum, discuss!  I appreciate all/any input whatsoever.
