Hi, you can run your cable through there. It will come out above your carpet on your passenger side. No need to pull the dash apart or anything.
I don't know how big your amp is but I was able to mount my Alpine amps under each seat. If yours will fit under there just be careful to check under your car were you will have the mount screws. On the passenger side there is a bunch of small lines.
I think they are for your fuel system. If they won't fit there a bunch of people have put their amps in the section under the rear strut brace. You have to pull the styrofoam piece out.
Good luck and show us some pics of your install after you are done.
