Can stock battery and alternator support another 15" subwoofer?

pics or it didn’t happen

 

Ahhhh....you quoted the first rule on the internet (which i broke). I’ll have to go over to my shop a take some pics. It’s really rainy for the rest of the day, so don’t hold your breath...

 

It’s a poor pic that i found on my phone. You can kinda see the smaller white battery tray standing up vertically right in front of the battery. There’s about 1.5” length different between the two. That smaller tray was out of my 2004 AC truck. The larger tray (that the battery is now currently sitting on) was out of my 2000 AC.

I did a little research and from what i read, a larger battery came with the factory towing package (along with the high amp alternator and battery). I have no idea if either my 2000 or 2004 trucks had towing packages or not, but my 2000 did have a larger battery and battery tray. My battery size is a Group 27F. I think the standard battery size is a Group 24F?
