nope. birch box is at most 75 lbs or less this aint MDF, my old birch ply box for 2 18s was birch and its not even 120lbs. the orion and audiopipe together is about 75lbs. you have about 450lbs max. about the equivalent of two fat people sitting in your car.

Ok, there's also a custom amp rack holding the amps so maybe an extra 20 pounds for that? So maybe 500lbs instead of 700?

doubt you'll find helper bags for a car with rear struts. Custom springs are probably the only option....
