If I could help, I would. Unfortionatly I have a kinda similar problem. I bought 2 Pioneer 10's on boxing day. Problem is, there was no info with them cause it was an open box thingy (cardboard boxes got all wet or something.) They still honor the warentee, plus I bought extended service plan, so I know I didnt get screwed. ($134.37 cdn after tax + 2yr extended warentee)
So now I have to find out how big to make the box. Ports and all that stuff too. Size is not a problem for me as my trunk is massive.
Im sure someone will be around that can answer your question
