Ideas to Lower Port Tuning

Well Polyfill costs like $5 and is easily removable so try it, and if you don't like it, it's not like your out a ton. I've heard of a lot people using it in ported boxes, never played with it myself, even though I do have a bag laying around here somewhere.
If I don't end up totally changing subs, etc I think I'll give this a try.

 
if you mount the sub inside out you have little more space
I know, but then I can't put my targa top in the back. This box is a literal perfect fit, couldn't be any bigger (other than just extending the top out) and still store the targa top. I got real lucky it was for sale near me, built for an SDC2.5 and up for sale just as I bought the sub.
