ok. i decided to stick with the psw10 and just bought another one last night. It sounds freaking awesome. But do i need to go into setup and change anything? I already changed the original one to 80hz and the other touch ups you and other forums suggested......do i need to just leave the new one hooked up and it will pick up on the setup or do i need to go into the menu and do something for the new sub.....or easy as plug it in? thx.
