i want to relocate my battery to under the passenger seat, and i've found how-to's on relocation to the trunk...

my questions:

1) where would be a good ground under the passenger's seat?

2) is there anyway to just reuse the OEM battery terminals? if not, i assume they just sell battery terminals at pep-boys?

3) how much is a mini battery box and where can i find one? (lancershop.com doesn't have 'em)

thanks!
