its not a safe route but you could wire each sub to two ohms them two subs to one ohm and bridge at one ohm. certainly do not recommend it but it will give you more power. i blew one of my old audiobahns doing this. but if you want to give it a shot, the most youll do is fry a voice coil. the comp vr isnt too exensive. you could get another.
or get a one ohm stable amp and youll have no worries
