Good Morning, I just came across one of your posts and your info regarding enclosure builds. I just ordered 1 12' BTL and I'm looking to install into a 2009 Dodge Challenger. I'm not looking for anything crazy, just a solid design that will fit in the trunk and is tuned to suggested frequencies. I don't know if it matters, but the model I am purchasing does not come with the 8 inch sub installed in the rear deck, so there is an opening from the trunk to the deck, perhaps the port can be directed there, with the subs facing the rear. I'm not sure this is possible, but any feedback would be appreciated. Thanks again.
