lol, my bad. Im just trying to find the info and advice out there so I can learn. Question was hella vague, but mainly I want to understand the pluses of adding an extra battery to the sound system, and details surrounding that. I want to understand how it works.
MOST vehicles can handle 1200-1500 watts rms on factory electrical system. Swapping to a good AGM front battery and big 3 upgrade is always a great upgrade though.
