So i will be adding a second amp for my interior speakers, a Rockford P500.4 do you guys think one SK-BT100 battery plus a red top under the hood will be enough for this set up

Try your local sears and get a Die hard platinum if you are tight on cash. I have had there AGM group 31 for over 2 years and its has held up very well.

If your smart you can find good battery's for really cheap. I can get new Agm 31's for under $90.

Yeah but think about how much shipping would be. I know for me shipping for a 31 is around 300 dollars.
