So here are the pics of the boxes that we've built for the g35 trunk. Some have shown some interest for flush mounted subs. Here's the one I've had in my trunk for a couple months.

12" Solobaric Flush Mount - Ported or Sealed 2.25 cuft


12" Solobaric Flush Mount - Ported or Sealed 2.25 cuft.


2 - 12" Kickers - Sealed, Internal Volume a little bigger than 2cuft.


We did the single 12" sealed originally and now it's ported. Nice and loud for the single 12". Next week we'll be testing out 2 JL w3s in the dual box. We'll be trying 10" subs in these as well once we get a hold of some. Wondering if we could get 2 15s to fit... but it doesn't seem likely. Maybe 3 10s" with a slight angle to them? So many options.
