I have a 160 Alt...I don't need an alt. I just need an extra battery. I'l just get a 700CA battery. I Have 0 gauge power and ground. I'm just adding as a precautionary measure.
I have a DD Audio M1 amplifier 1200W@ 1 ohm running a single DD Audio 3512H D2 Supercharged. What amp battery do I need to add to my setup as a 2nd battery?
