I ran my btls in 7cube boxes so i dont see why not. I personally would put sub and port on the face and fire towards the rear. Unless...your seats fold down and you are planning on firing into the cabin and sealing the cabin off from the trunk.
Wow you give up quick. You need more detail before you tell someone its impossible to do something. Building the box in the trunk is always an option... although more difficult.
Ive ordered 4 15's(seperately) in the last month and on average its been 10 days from the time i placed my order to them showing up at my door. Not bad from las vegas to the top of michigan.
Have you hooked it up to see if its working? I dont believe its the awt series, i googled it and the pics dont look like this one. Although i could be wrong, not too familiar with audiobahn...
Bracing, bracing, bracing...especially when running beefier subs. Double, triple check calculations. Sucks ass when you get done and all your hard work is for nothing because it sounds like crap.
