Hello all, this is my first post. I want to add a stealthbox made by jl audio and an amp to dirve the sub (either a JL or Rockford amp) H:2.5" W: 7.5" L: 11". I'm looking for a place to install the amp where it is hidden. I have a Nav & CD changer. I don't want to get rid of the spare tire. Need some advice on where it could be hidden. Thank you.
