Hello. I have a Orange OBC410 bass cab that runs 8ohms. I also have a old Ampeg SVT 400t. I know the 400t runs to amps at 200 watts each at 4ohms. I want to know if i can play that with my Orange cab. My OBC410 can handle 600 watts. Can someone let me know if it is safe to play this together? Or if ill need a new head?
