Hey Sound, if you have a system setup so that the wiring runs into the trunk with an inline fuse holder, you can use someone elses battery to hook up with jumper cables and even if the battery is dead, it will allow you to pop the doors, thus allowing you into the car, and able to pop the hood (to boost the battery). ALTHOUGH, if some people considering this are willing to throw down some extra cash, I believe you may be able to run CRAZY THICK guage wire off the two terminals on the battery, and run it into the trunk, mounted on a wooden block or what have you, so you could therefore boost your car from the trunk
