For my 2 12" L7 ported, im gonna have them on a zx1000.1 (probably more likely) or a zx1500.1. I have an 1800 watt amp wirin kit (pretty sure its 4awg), and Im gonna do the big 3 with 0 awg. In my 2007 pontiac g6 v6 sedan, with stock alt (120 amps is what it said online about it, so i wont change it), do i need to change my OEM battery with a yellowtop or diehard battery? OR can i keep my stock and just put another battery by the amp?if so which battery do you reccomend? Keep in mind im getting 2 headrest screens and a touchscreen pioneer double din, and a neon sign in my trunk with 2 electronic trunk pop actuators, but i never play music without the engine on and running. Any response would be appreciated cuz i been stressin out lookin all over this sight for some answers and really i just see people makin ******** comments to eachother. Thanks!
