I already have a 4 gauge wire running to my trunk for my stereo, so my question is, is this too small for a battery lead? Also, those who have put the battery in the trunk in the 4k, did you use any kind of a battery box and/or vent hose or is this there enough air in there not to worry about gas buildup? Thanks -Marc- 87 4kq.... need to make room for the turbo :-)
