Alright So i'm puting in a box at 14.5in tall, 29.5in wide, and 18.5in deep. it's tuned to 32hz with a a type r 12". NOw my only concern is that i've got a navigation box back there. is there going to be any interferance with the navigation while the sub is in motion... if there is i'm going to rethink this whole system setup

 

As long the box isn't touching the Navi unit you should be fine.. I've yet to see a story where the sub interferes with the navigation unit.

 

awesome... thanks for the feed back
