Audio Systems: Power wire installation, trunk flooring, buick regal

Question
Kind of a hard one, but i'm reaching here. I'm trying to run a 4 gauge power wire from the battery to the trunk of a 96 buick regal. I cant find any holes or anything in the firewall to get it into the car. My previous cars had Precut holes with rubber plugs, or i went thru the steering hole. Is there a spot i can come thru or a safe place to drill?  

Answer
If you really can't find a place to squeeze it through (the steering column can sometimes accommodate it if you enlarge the opening or squeeze real hard) then I recommend that you run it under the car. There is plenty of space along the frame members where it can be attached and brought up through some opening in the trunk area.  Or, you can easily find a place to drill a hole through the trunk flooring.

Hope you find a suitable place.
