No, only because I have not been convinced that aluminum cable could carry the current needed to start the engine and keep all things going with the battery in the trunk.
ThumperDart has looked into some type of Copper coated 2 gauge aluminum cable that supposedly works, but I have not heard enough feedback to justify it.
The bulkhead connection was interestingly mentioned that could make a smaller/lighter gauge cable work.
Anyone want to add a comment to that?
