Nyaim Posted September 11, 2013 Report Share Posted September 11, 2013 i have a 90 amp alternator on my 2011 kia sportage, currently have one yellow top optima up front and thinking of adding another one or 2 in the back. would my 90 amp alt be able to keep the one up front and maybe one more in the back? already done big 3... voltage drops to about 12 when playing full tilt Pioneer AVH3200 DVD2, Pioneer 6.5" 2 way 60 Rms Kevlar4, Pioneer 6x9 2 way 80 Rms Kevlar1, Kicker Solo-Baric L7 15-Inch 1000 Rms1, 1000Rms Hifonics Monoblock Amplifier1, 800Rms Hifonics 4-Chan AmplifierAudio Control EpicenterKicker Kx3 Crossover120AH Power cell Battery (Main)Pioneer AVH4300 DVD HU2, 500rms D.A.S 10B 10' Mids 2, 500rms D.A.S 8' Mids2, 300Rms Pyramid TW47 2" Super Tweeter2, SA-12 D4 Tuned @ 33hz @ 4.26 ft^31, 1000Rms Rockford Fosgate T1000bdCP Amplifier - Birth sheet 1576Rms1, 1000Rms Rockford Fosgate T1000-4AD Amplifier - Birth Sheet 1496RmsAudio Control EpicenterAudio Control ESP2Clarion Mcd360 Electronic CrossoverKicker KQ30 30-Band EqualizerRockford Fosgate Rfc10hb 10 Farad Hybrid Digital CapacitorYellow Top Optima (Main) Big 3 Link to comment Share on other sites More sharing options...
Omega5002 Posted September 11, 2013 Report Share Posted September 11, 2013 I say you should be fine, if you're holding 13's with a 2nd batt, that means it's balanced between alt and batt power, and batts won't be drained, now if you stay on 12's often, then I'd invest in a battery charger, and charge the batts at least once a week. 2003 Kia Sorento Team Subsonic LowsTeam Bassin' on a Budget2016 Rebuild Under Construction Best score: 150.2 at 40hz (3k, 2 Custom HDC3 15's) Usaci style(door open, in the kick) Link to comment Share on other sites More sharing options...
Miguels Posted September 11, 2013 Report Share Posted September 11, 2013 adding more batteries doesnt mean you wont have drop.. it will be okay for a few seconds then it will drop back to 12 and you will have dead batteries in a few days 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...
Nyaim Posted September 11, 2013 Author Report Share Posted September 11, 2013 i was hoping it would at least keep the voltage in the 13's im not always playing full tilt, wouldn't they charge back up when im not through the alt? im playing full tilt for maybe 2-3hrs a week total...

Adding a 2nd battery does help when you're running over 1000 watts, and sometimes, your voltage drop will decrease because you have enough battery power to maintain voltage, but the alt is equally important as well. 2003 Kia Sorento Team Subsonic LowsTeam Bassin' on a Budget2016 Rebuild Under Construction Best score: 150.2 at 40hz (3k, 2 Custom HDC3 15's) Usaci style(door open, in the kick) Link to comment Share on other sites More sharing options...

Running more batts always help, just gotta make sure they are properly charged (and in good shape) 2003 Kia Sorento Team Subsonic LowsTeam Bassin' on a Budget2016 Rebuild Under Construction Best score: 150.2 at 40hz (3k, 2 Custom HDC3 15's) Usaci style(door open, in the kick) Link to comment Share on other sites More sharing options...
EricDoody95 Posted September 11, 2013 Report Share Posted September 11, 2013 it can, but it takes time. what your alt does is charges your batt(s). And of course, the batt being charged (up front) has to charge the back ones, and before that is done it has to be fully charged. your best bet is getting a new alt if you plan on running that much power. I recommend excessive amperage alts. 2003 Honda Element Pioneer DEH-9400BT Big 3 XS Power D5100 Sky High CCA (2 Runs 1/0 Gauge) 2 XS Power D3100s 1 DC Audio 3.5k @ 1ohm. 2 DC Level 4's w/ XL Softies Custom Box tuned to 29hz CT Sounds 125.4 2 Sets of CT sounds Meso Components *North East Frequencies* Link to comment Share on other sites More sharing options...
