I'm going to be powering a BTL N2 15 soon enough and have never owned a BTL before. I'm not asking "how many wattz to make my sub thump," I'm more or less asking if, for daily applications in 4.5 cu ft tuned to 30 hz, the extra 1k watts will make a difference/if the BTL can handle sustained power for a long period of time. Also, I will have an Autocraft Gold batt with a 200 amp h/o alt and Big 3 in 1/0. So please just give me some opinions/what you would do. Thanks all!
