Could this work??
 

Your glove box behind the passenger seat has a box in it, if you were to take that out and use it as a model to make a box for a sub would that work? It would be ideal becasue the dementions would be perfect to fit into the area behind the passenger and drivers seat, using the sub mount that you can buy on the passenger side would sound like it may work fairly easily.
Thank you

There are folks here that have done that. Just use the search tool. One guy has (2) 10" RF's in both compartments.

Yeah, I've seen a few done that here :)
