one my friend needed to jump his car and i was the only one with the cables so it took us like an hour to get everything unbolted and we took everything out of my trunk just for some stupid cables under my subs
^my spare is under the car :D The jack and jumper cables are in a panel inside though- I doubt I could reach them without removing the equipment. Triple A to the rescue right?
As far as a spare- fix-a-flat can get you to a gas station, and if you have multiple batteries the chances of needing a jump goes down pretty low. I've left all kinds of stuff running all night- turned the car on and said 'hey, why are these lights on?' lol.
