1sickpuppy Posted May 26, 2011 Report Share Posted May 26, 2011 Is my stock 109 amp alt enough to charge and maintain a second battery? Or would I be better off upgrading my alt then adding a battery?

Supercharged DCs Posted May 26, 2011 Report Share Posted May 26, 2011 What amplifier are you looking to run??? Quote Bassless once again.

1sickpuppy Posted May 26, 2011 Author Report Share Posted May 26, 2011 Big three is going in first with 0 awg. Looking to run 0 awg from battery to distro block then 4 awg to amps.

1sickpuppy Posted May 26, 2011 Author Report Share Posted May 26, 2011 As far as the extra battery, I don't know what type. I just want to know if 109 amps is enough to even maintain two batteries with approximately ~2000 watts rms? Is it possible?

bdubii Posted May 26, 2011 Report Share Posted May 26, 2011 You might be able to get away with it if you don't listen to your system at full tilt often. With those two amps, assuming that they can put out 2000watts rms that will draw about 166 amps of current. If you exceed the amperage rating of your alt by more than 20% you can expect to have problems. 20% of 109 equals about 131 amps. And that is all assuming that you are going to be playing it at full tilt with your car not demanding any other electrical needs. I wouldn't want to do it but if you decide to the extra battery will help for sure but it would be good to replace your alt Quote My build, four 15's walled: http://www.stevemeadedesigns.com/board/topic/106855-07-tacoma-walled-off-with-4-15s/page__p__1487297#entry1487297 Link to comment Share on other sites More sharing options...
1sickpuppy Posted May 26, 2011 Author Report Share Posted May 26, 2011 Thank you to all who replied! I really lime the info and help I receive on this forum. I rarely turn my system up past half way. I'm not trying to impress anybody. I just like my music to be clear and clean.

bdubii Posted May 26, 2011 Report Share Posted May 26, 2011 I think you would be fine then. Especially running a second battery. But if you do turn it up just watch your voltage Quote My build, four 15's walled: http://www.stevemeadedesigns.com/board/topic/106855-07-tacoma-walled-off-with-4-15s/page__p__1487297#entry1487297 Link to comment Share on other sites More sharing options...
