I know I already posted a subject on this but I am still trying to decide what system I should get because I want to be heard from far away but I am also on a tight budget. I have decided that I am going to get 2 16kv.2s by elemental designs in a sealed box. What would be the best amp for these two subs and will this setup be able to be heard from far away? The subs are 650w rms. Thanks
