Hey thanks for the reply Jordy,

And to answer your question about how i got referred here; the answer is a little leprechaun named sean built a box for me a couple months back. I just asked him for just a basic box that would maximize SPL. When I picked it up, it was way above my expectations. He build me a 250lb monster which is rattling my car apart one piece at a time.
So he told me to check out this website if i ever wanted to get it tested. Just for peace of mind.
Would you want to hook up with me in the near future whenever you're not busy and do some testing?
PM me to set something up.

Thanks alot.
