You need more info to be able to say if batteries should be matching or not? lol Pretty sure my info is in my sig. but thats cool.

Karkov Posted June 6, 2013 Report Share Posted June 6, 2013 So, If i am going to be running 2800w of audio shiz. Do i need a second battery IF i have a 250a alt (at 14v) and one XS D3100? Would there be a big difference in adding a second battery? Best thing to do would be to get an accurate volt meter and watch what it does under full tilt of your setup, then decide if you need an additional battery or not. Does anything cut out? do lights dim? does bass get slightly quieter? So you currently have no under hood battery just power wire running back to your interior battery and you start engine and run stereo all off of it? My own personal opinion is to have minimum of 2 batteries with an after market stereo system. I.E. 1 under hood and one dedicated for stereo with or without isolator. Not saying you need big expensive batteries but a little something to help with voltage drops, even if you do have Big 3 and other wire upgrades done, or high amp alternator. Just my $.02 find something you can afford that works and you won't have any doubts if you should have added a 2nd battery or not. Good luck 2007 Chevy Tahoe (SOLD) 12 ~ FI Audio X series 10" w/BP option 2 ~ DC Audio 5.0K @0.67 3 ~ DC Audio 5.0K @1.0 2 ~ PPI 3 way sets (not installed yet) 1 ~ RF T400-4, 1 ~ RF T600-2, 1 ~ RF T600-4 4 ~ CT Sounds 5.25" Strato comps (rear fill only) 1 ~ XS Power D4800 1 ~ XS Power D3400 8 ~ XS Power XP3000 160 stock alt, Mechman 370 Elite, 185 DC Power 320+ Sq.

hankfan79 Posted June 7, 2013 Report Share Posted June 7, 2013 I run 2,200 rms, a D3400, and a 230A alt. Also have big 3 1/0. I have no problems. Extra battery isn't needed but wouldn't hurt. $500 for another battery? PASS on that! Link to comment Share on other sites More sharing options...

You'll also have overhead if you plan to upgrade equipment later. Also, pm an XS power partner here to get good prices on batteries. Thats my opinion. Edit: Just noticed you already have a d3400. That being said, the 3100 is rated to support 5000 watts as an auxiliary battery. Link to comment Share on other sites More sharing options...
