Hello everyone, I plan on doing a build in Hyundai Genesis Coupe 3.8, this comes stock with a 130a alternator. I posted a similar question on the diyaudio forms and wanted more opinions. The build I plan on doing will roughly come out to 3600w rms. One amp doing 400, another doing 220, and the mono block using 2500-3000. It was recommended by others that I go the route of installing two AGM batteries (one starter and the other an xs 750) before considering an alternator upgrade. I was looking to see what others opinions were, if you think this would satisfy the system or if I should just get an upgraded alternator and agm starter battery. Any insight is appreciated, thank you.
P.S. The music I listen to is hip-hop and bass-heavy music, I wont be listening full blast all the time, but I would like to crank it every now and then and not worry.
