so im in need of a extra battery. i got a die hard platinum under the hood. big 3 done. im going to be using 1500rms daily, i was thinking about getting a deep cycle marine battery from napa and using it. how are these? i need something cheap but will work good. i know most people will say kinetik but right now i dont have the cash for it so i need a CHEAP alternative for now. i can get those napa batterys for about 70$
