i have a box, which will fit UNDER a jump seat, which means i will not be removing it, what is the best method to bolt this to the truck? it must be secured by means of screws or bolts, in some way or another (glue or tape does not count) as per insurance regulations, for theft reasons, there must be a hole in the truck, that the sub was mounted to...

i am skeptical drilling a hole through the floor in the truck, to run a bolt... any other thoughts?

 

How about getting some of those metal l brackets and screwing to to the floor with like a 1/2in screw or so..

 

bolt that ***** through the floor. use some silicone to seal it up and youre good to go
