How do I get subs in my 07 X-Runner?

I don’t want to place subs directly behind my seats. I’m looking to probably place them somewhere inside the vehicle to whereas it’s not taking up space from sitting. Any ideas would be great. I want at least 2 10" subs and I want it to punch loud.

Go to crutchfield they have subwoofers enclosures to pickups and trucks.
