uhoh_45 Posted February 11, 2009 Report Share Posted February 11, 2009 your back batts should charge when the cars running unless you've not got them hooked up to the front batt/alt and yeah replace the stock batt with the 1400 and put the 2000 in the back Quote R.I.P!

SundownTL3.2 Posted February 12, 2009 Author Report Share Posted February 12, 2009 ok....do i need a fuse for big 3?? Quote 2004 Chevy Tahoe LT........... THINKING Link to comment Share on other sites More sharing options...
creyc Posted February 12, 2009 Report Share Posted February 12, 2009 Fusing the big 3 isn't necessary unless it makes you feel safer. I'm guessing your batteries are probably fairly well drained too. If you run your subwoofers every time you drive somewhere you don't get much of a chance for your batteries to charge up. When I had a stock alternator I would throw a 40A battery charger on my truck every week or so to top the batteries up. Your stock lead acid battery doesn't like sitting uncharged for very long either. More than likely it's in a pretty sad state and everything's running off that 1400 in the back.
