Re: Help. 4 15'' hx2's
when selecting a battery for a system that will be ran when the car is running, you want a battery with a very low ESR .
i don't recommend using a system of this caliber with the car off ever unless you want to but 12 huge deep cycle batteries and you can charge it for 24 hours after play..
knowledge is powerful but imagination is exponentially powerful!
experience is key! otherwise life is uneventful and pointless..
keep in mind you have a great mind and remind yourself to be mindful.
