Which battery should I hook my amp to?

[ComatoseLlama]

Going to be installing my subs in the truck because why not, no one sits in the backseat anyways. It’s a Rockford 600W rms system

Not sure which battery is the best to hook the amp up to though, does it even matter?

Thanks

Shouldn't really matter with both battery's connected in parallel

i have a 97 obs did mine on the driver side battery was easier for me to drill a hole with a rubber bushing to protect the wire on the driver side..

I used the driver's side battery for that on my Blue Truck.
