i did mine under the carpet...didn't really have any problems with it at all. i went from the battery to underneath where the cabin air filter is, and down into the front passenger fender. then down into the black hose where the power wires go for the mirrors, windows, etc. from there i went into the car and under the carpet. i then followed the door trim back to the back seat. its not the best setup, but it works for me...
ah see...I caught hell cause I went straight under the console...thats ruff way to do it but there's not a single sign of a 4g wire there
