The car is a 2002 chrysler intrepid, and I have 37.5" X 14" X whatever depth I need. 3 Type R 10's, and I'm not sure about which way to fire them. The trunk is really isolated from the cabin. Even the old 6X9 holes are in the cabin not the trunk. So I'm not sure which way to fire them. Also not sure whether to go ported or sealed. They are in 3 seperate sealed enclosures as thats all I had at the time and the sound like they're missing something, they kinda fall off at some notes. Any input would be helpful. P.S. I've never built a ported enclosure before, so lengths and widths will be appreciated.

Cheers.
