akuma4u Posted January 24, 2016 Report Share Posted January 24, 2016 Hey i have an xspower d1200 it says its perfect for systems from 1500-3000 wrms , i had it running on a system that was 1000wrms i am doing a rebuilt with a help of a pro this time , looking to go about 2000-3000rms he says that for every 2krms i need a d3100 battery.. but according to XS power to run 2krms my d1200 would be sufficient. D3100 batteries are good for systems from 4000-5000rms+... so whats up with that? why would he recommend a d3100 for 2000rms when xs power lists that big ass battery for 5000rms systems? for added headroom? would i still be ok with my d12?? thanks Quote Link to comment Share on other sites More sharing options...
hdorre Posted January 24, 2016 Report Share Posted January 24, 2016 Is the D1200 your starting, or additional batt? How big is your alt? What are you wiring to?

Miguels Posted January 24, 2016 Report Share Posted January 24, 2016 yeah its the same thing i say.. if 1 D3100 is good for 5000 watts why do we need 5 of them on a 9k amp or 3 on a 5k amp? it could be because of the alternator output.. if you have an alternator that can supply the demand you don need that many batteries..

Miguels Posted January 24, 2016 Report Share Posted January 24, 2016 no.. you will play longer but eventually you will be digging on battery power.. you can add 10 D3100 and still have voltage drop.. the alternator is what makes the power the batteries just store it it be cheaper to buy a 250A alternator and a tiny battery in the rear like a d1200 or even the d935 Quote my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
Miguels Posted January 24, 2016 Report Share Posted January 24, 2016 maybe you didnt get my post.. battery rating means squat if you dont have the alternator to support the demand.. get an alternator Quote my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...

Miguels Posted January 24, 2016 Report Share Posted January 24, 2016 well look at it this way.. 2 D3100 will run you $728 and thats not including shipping in into Canada.. with those 2 D3100 you will be around 160 heavier and you will still have voltage drop.. an alternator even if it dont fit your car $499. so that means you have $228 to pay someone to make the alternator fit.. you will save weight and have your voltage where you need it Quote my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
