Powered subwoofer power cable
If you're already looking near the battery, I'm assuming that you're talking about the power wire. You should just crimp a ring to the end of the cable and put it right under the nut on the battery post, or the power post @ the fuse block. Make sure that you have a properly rated inline fuse close to wherever you connect.
EDIT: and this probably could have been added to your original post about running this wire
I plan on running it thru the grommet on passenger side fire wall along the door sill to the trunk.
Any problem of running 2 items (GPS, Radar detector) off of the TAP wire (going to pwr window) in right front passenger area?
