I used the general idea from Remmy's DIY In floor subwooder kit on my 04 civic and I am almost done with mine! I will post lots of pics when I finish it... I am actually surprised at how well it works, just about as good as the original box it was in! My wife, a buddy of mine and I worked on it from 5p until about 9p in the driveway and the only thing I have left is carpeting the sub and flooring! Expect pictures soon!

 

if your system turns out good ill probally do something similar. I know itll be fresh

 

It does look really good so far and it sounds really good as well
