I thank my luckystars for my large terminal cups... without it, I would've looked more like a fool trying to get the darn thing into my boot... not to mention a sprained back.. I've got a bit more wood on my box than the normal square box, plus an amp as well...
a normal person would not be choosy about how they carry their enclosures from the workplace into the boot, and you'd be relieved to find any sort of grip on the bulk.. not to mention slippery, once you get the carpet on it...
