Not sure what you mean there. you could tune it higher if needed, but higher tunings tend to be one note wonders and some times doesn't help db wise. Are you planning on competing ? How do you plan on "porting through the rear deck" ? You going to run a big square port in the middle ? Round ports through the rear speaker holes ? Need a few more specifics and we'll be able to help you a lot better and quicker lol.
