So getting ready to start on my build. This is going in a 04 Chevy Astro awd. Not gonna be walled or anything insane. I have a Astro because I need the room to haul shit. For wiring I bought two of the LA $45 0g wiring kits and one 4g. I have a 120amp alt already installed, its from a RV conversion motor for the Astro. Kenwood 995 head unit,amps MB Quart Onxy series 4125 and 1500. The fronts and rears are Hi-Vi 3-ways I bought from Madisound. Subs are a pr
of frankenwoofer 12s. They are going in a center console enclosure sealed.
My question is do I need a second battery or is the upgraded alt and larger battery enough?
