Im looking to go behind the seat.. and I am gonna make the custom box.. but before i do.. im really wanting some 18's being the truck is gonna be used for sound/show.. any of you got 18's back there or 15's? if i cant go with 15's or 18's ill probably get 4 12's.. but.. im really wanting 2 18's.. anyways if it is possible for them to fit back there.. i dont got any measurements from subs cause i havent decided but if its possible.. what all will i pretty much need to do.. help greatly appreciated.. pretty much just wanting to know if ill need to remount the seat a little closer up front and so forth.. just go into detail.. on what ill need to do or if its even possible.. thanks..

 

Basically for 15s and 18s you would have to take the back seats/consoles out, or do a blow-through into your cab and mount the subs in your bed. Basically without doing either of those modes, you could proablly fit 4 shallow mount pioneer 12s, but you wouldnt be giving them the optimum space requirements, or shallow mount 10s. And with 15s or 18s, be prepared to do mulitple layers of sound deadening all over you truck.

 

If you want 15s or 18s AND you want them to sound good and get crazy loud. You'll need a blow through.
