Mangler why the rolling of eyes when refering to my success with the Dyna Batt. Yeah I don't live in an extremely cold climate as the coldest it gets on O'ahu is 45deg. in some areas, can't say that for some of the outer Islands that get much, much colder than that, but since I don't live on the outer-islands that's not an issue. I really haven't encountered to much of any problems with the Battery, I've had it on for over a year now. I think the Dyna-Batt is prone to drain quicker though than a regular Battery from my experience and so I suggest not running your radio while car is off to long. The Dyna does re-generate very fast!
I'm also considering moving it to the trunk, like to have more space up front, plus it will reduce the amount of damn wires around that area...
