Karlswinslow Posted August 26, 2014 Report Share Posted August 26, 2014 i have a 90 amp alt running the car now and no battery in the trunk. and as of right now if i play my car for a little long, the amps will cut off.. I'm doing 2 x12's on a 2500watt hifonics amp.. can i get away with doing just 2 3100 xs batts in the rear and my yellow top upfront with the 90amp alt? reason being... I'm on a budget to pay for the batts and box.. so its kind of hard for me to go ahead and do the alt right now.. Quote Link to comment Share on other sites More sharing options...
hdorre Posted August 26, 2014 Report Share Posted August 26, 2014 for most people, a D3100 is $370. You're thinking about 2.. so $740. Why not a HO alt ($450ish), and upgrade the starter battery? All batts really do is HOLD a charge.. not really supply. Thats the alt's job. Sure, you could play for a while on batt reserve (in the 12s, then 11s, then so on).. But I like to HOLD voltage.. preferably a tad higher.. 13s and 14s.

Karlswinslow Posted August 27, 2014 Author Report Share Posted August 27, 2014 yeah man, its hard right now haha. i was thinking upgrade amp but i can't do that right now. have to think about electrical. in other cases, what do you guys think about running 2 yellow tops in back? cheaper for me but I'm not sure on what batteries are best now.. and regarding the alt situation, don't go for a 140 amp? the most i can get for my specific vehicle is a 200amp for 420$ and the 140 is budget wise best for me seeing as i can get it for 150. what do you guys recommend? keep in mind, ill take the loss for now on having a lower power amp for my subs and under power them Quote Link to comment Share on other sites More sharing options...
evermaxx Posted August 27, 2014 Report Share Posted August 27, 2014 get highest amp alt you can, the 2 yellow top should be good for that amp.

Pioneerchuck Posted August 27, 2014 Report Share Posted August 27, 2014 I would recommend getting a larger alt before buying a shit load of batteries. Quote Link to comment Share on other sites More sharing options...
Karlswinslow Posted August 27, 2014 Author Report Share Posted August 27, 2014 thats true.. the way its setting up.. it looks like ill have to piece together everything.. so first ill do the 200amp alt.. but the 2 yellow tops in back, how does that compare to 2 d3100.. will i be better with the XS incase i change amps?

hdorre Posted August 27, 2014 Report Share Posted August 27, 2014 but the 2 yellow tops in back, how does that compare to 2 d3100 It doesn't.

REH Posted August 27, 2014 Report Share Posted August 27, 2014 Definitely do that alternator first, the odds are that alone will be plenty enough to run this hifonics 2500 you're using for now and give you freedom to save some cash for more upgrades on everything.
