Sky Posted January 16, 2018 Report Share Posted January 16, 2018 I have 2 stock batteries in my 2011 6.7 f250. Going to be running a 3500 sub amp and whatever my door speaker amp will be. I’m guessing around a lil over 4Kish power. Any idea if I upgrade my batteries to some decent AGM batteries that would suffice? Or am I looking at a upgraded alt as well and extra batteries? I have 3 xs power 3100s but there way to big to fit under the hood and just trying to justify the need of them anymore. 99 F-150 Build Log Link to comment Share on other sites More sharing options...
Markous Posted January 16, 2018 Report Share Posted January 16, 2018 What kind of alternator power do you have to feed that gear?

Sky Posted January 16, 2018 Author Report Share Posted January 16, 2018 Stock. I think it’s 130-150. I don’t think I have the 200amp HD one. Alt upgrade and 2 agm batteries under hood? 99 F-150 Build Log Link to comment Share on other sites More sharing options...

That plus a couple of runs back to some dual inputs on the sub amp and i would say you'd be ok. Just my opinion based on my knowledge though. There are other variables that if you could provide would help get more/better advice. Such as what amp? planned intended final impedance amp will see?

Sky Posted January 16, 2018 Author Report Share Posted January 16, 2018 Soundqubed 3500 at 1ohm. I was originally thinking of hooking up my 3 3100s in a toolbox in the bed. But just don’t think I need 5 batteries in total. For only about 4.5k of power. 99 F-150 Build Log Link to comment Share on other sites More sharing options...
Markous Posted January 16, 2018 Report Share Posted January 16, 2018 I'm running what could basically be described as a scaled down version of what you have planned, about 2400w total (rated). I have a 250A alternator with three group 65 batteries, i very rarely see anything below 13.8v.It's probably overkill but i'm fine with that. You might be best off with a HO alt and the three AGM's, two under hood and one closer to your sub amp.

Sky Posted January 16, 2018 Author Report Share Posted January 16, 2018 Rarely below 13.8 is spot on. Im thinking I’ll upgrade alt and batteries under hood and go from there. See how volts hold up and add a 3100 if need be. 99 F-150 Build Log Link to comment Share on other sites More sharing options...
