Bass4Lyfe Posted May 25, 2008 Report Share Posted May 25, 2008 Okay so this is a STPUID quesiton but why would you guys want more than 1 battery? Everyone has it and I'm just wondering. I mean, the system is only playing when the car is ON so wouldn't alternators cover it? Wouldn't the only reason to have >1 battery be to play it for hours when the car is off?

Wouldn't the only reason to have >1 battery be to play it for hours when the car is off?Haha thanks the fact you can play it longer with the car off is a plus..........BUT its so you can stay at peak volume for longer amount of times...i.e. steve has enuf batteries to build a house and 4 alternators (plenty of power) and he even has a voltage drop...he revs his engine to get the most out of his system and keep the batteries up to full.....they keep your amps putting out the most power........you have one 12v battery that stays at 14 volts full charged.... 2 of them will help keep your system stay up to full capacity longer then say one with just 1 battery......hell w87will has a 300 amp iraggi alt and just 1 battery and he says that he isnt seing full capacity because that battery cant re-charge fast enuf...multiply batteries gets rid of that problem and keeps your system better (might not make sence, but it is all good) Quote My F-150 Build GET ON THE BANDWAGON what if they tried messing with the amps when the subs werent louder hahah jk Link to comment Share on other sites More sharing options...
darvex Posted May 25, 2008 Report Share Posted May 25, 2008 It all depends on the current demands of a system. Most small systems do ok with a single upgraded battery. Add a little amperage demanding multi-amp system to a car and then you'll have to consider what's best for feeding it. I say anything over 100 amps in current draw requires some attention in the charging / storage department. Quote Link to comment Share on other sites More sharing options...
Bass4Lyfe Posted May 25, 2008 Author Report Share Posted May 25, 2008 okay so i guess the main reason is the battery cannot charge fast enough if you only have one? i'm about to upgrade my electrical so just wondering Quote ~Matthew 1998 Toyota Camry XLE V6 3L (1) ScyTek Astra 4000RS-2W-1 2-Way Remote Start Alarm with Shock and Proximity (1) 20% Tint All Around (Gately Audio) (1) 250 Amperage HO Alternator (1) Big 3 Done In 1/0 (2) Kinetik HC2400 Power Cell (1) Alpine IVA-D106 Receiver (1) Peripheral Video Bypass Device (4) Alpine SPS-17C2 Speakers (1) Alpine KCE-422i iPod Control Interface (4) Sheets Dynamat Extreme; for speakers (1) 10 Square Feet Hushmat (Trunk & Rear Deck) (4) DC Audio Level 4 15" D2 Subwoofer w/ Level 5 Coils (1) Wall Built By David, Tuned to 32 Hz (1) Rockford Fosgate T40001bd Amplifier (1) Stinger 1/0 Wiring (2 runs of + 2 runs of -) (1) Stinger Volt Meter Link to comment Share on other sites More sharing options...
spl explorer Posted May 25, 2008 Report Share Posted May 25, 2008 Long story short. It's harder to drain 4 batteries then it is to drain 1. So you can keep a higher voltage for a longer period of time when pulling some massive power.

Charger Posted May 25, 2008 Report Share Posted May 25, 2008 Big systems draw big current. I'm not going to rely solely on an alternator to feed my power-hungry babies. The more batteries the better in my eyes.

fourlug Posted May 25, 2008 Report Share Posted May 25, 2008 Most alts cant keep up to current draw of a stereo; 70 amp alt @ 14.4v = 1000 watts (at 100% efficiency) So anything over that will draw from the battery. Quote Link to comment Share on other sites More sharing options...
TechSys Posted May 25, 2008 Report Share Posted May 25, 2008 My amp draws over 500amps (I beleive 545 but can't remember right now). My alternator outputs 350amp at 2k rpm. The alternator runs the system when the vehicle (in my case a van) is running. When the amp hits a good bass note it'll cause too much of a demand on the alternator. The battery then kicks in to account for the extra power needed. Once the bass note is done, the alternator then turns around and starts charging the battery. Even with my 16 volt battery bank I am seeing a voltage drop. 14 8 volt 1000amp batteries wired to 16volts should, if my math is correct, be roughly 7000amps. At idle my voltage will drop down to 14.5 volts (not really good for a 16volt system). At 2k rpm, the voltage stays at 15.9 constant. In short, it take power to make power.

Bass4Lyfe Posted May 26, 2008 Author Report Share Posted May 26, 2008 got it. thanks guys i was just wondering but i think i get it now Quote ~Matthew 1998 Toyota Camry XLE V6 3L (1) ScyTek Astra 4000RS-2W-1 2-Way Remote Start Alarm with Shock and Proximity (1) 20% Tint All Around (Gately Audio) (1) 250 Amperage HO Alternator (1) Big 3 Done In 1/0 (2) Kinetik HC2400 Power Cell (1) Alpine IVA-D106 Receiver (1) Peripheral Video Bypass Device (4) Alpine SPS-17C2 Speakers (1) Alpine KCE-422i iPod Control Interface (4) Sheets Dynamat Extreme; for speakers (1) 10 Square Feet Hushmat (Trunk & Rear Deck) (4) DC Audio Level 4 15" D2 Subwoofer w/ Level 5 Coils (1) Wall Built By David, Tuned to 32 Hz (1) Rockford Fosgate T40001bd Amplifier (1) Stinger 1/0 Wiring (2 runs of + 2 runs of -) (1) Stinger Volt Meter Link to comment Share on other sites More sharing options...
