andym85 Posted December 4, 2009 Report Share Posted December 4, 2009 should be fine for burps...but i would get at least one more... Quote i likes me some audio stuff... Link to comment Share on other sites More sharing options...
MXmike800 Posted December 4, 2009 Report Share Posted December 4, 2009 i would think the altS would make it all gravy maybe like andy said just toss a batt in the back. Quote Link to comment Share on other sites More sharing options...

andym85 Posted December 4, 2009 Report Share Posted December 4, 2009 p.s. i am not responsible for any problems due to low voltage... which honestly shouldnt be a problem with two alts... Quote i likes me some audio stuff... Link to comment Share on other sites More sharing options...
JPagan Posted December 4, 2009 Report Share Posted December 4, 2009 I think you would be fine with 1 alt and 2 batteries Quote Link to comment Share on other sites More sharing options...
Nightshade Posted December 4, 2009 Report Share Posted December 4, 2009 I run 2 Sundown 2000d's in my car for daily and burps. Daily I run them each at .5 ohms. My electrical consists of a Deka G34 up front, 2 XS Power D 3100's in the spare tire well, 3 runs of 0 guage from the + to the rear, big 3 done in 0 up front, and a 260 amp Iraggi alt. The setup doesn't drop below 13 volts full tilt. I am getting ready to run a set of 0 guage wires to the back from the same place where the alt is grounded up front. That should help me gain a few tenths spl and voltage wise since there is some drop. For spl I run the same amps strapped at .5 ohms, so each amp see's .25 ohms. They will protect unless you roll the volume up gradualy. The electrical is the same as the daily electrical. I do not drop below 13.3 on a full tilt burp. I haven't clamped the amps since I added the new alt to the car but when I had the stock and the voltage dropped to 11.8 on a full tilt burp I made just over 5200 watts. I would say I'm much closer to 6K watts now. I hope this helps you out some.

Marlo Stanfield Posted December 4, 2009 Report Share Posted December 4, 2009 If you're planning on having dual alts then I'd suggest something like a Northstar NSB-70 under hood + (2) NSB-125s in back. Obviously using the appropriate power/ground wires also and you should have a pretty rock solid electrical setup for that power. Personally I'd just get 1 big alt, nice under hood batt like mentioned above, and (3) NSB-125s out back. Quote 1998 Ford Explorer Eddie Bauer... New setup, old ride...

Reason for dual alts is because I have room for them along with one good beafy batt under the hood. It's hard to fit two batterie in back if not imposible unless I had a bed cover. So if I can get by with two alts and a good batt I'll give it a shot Quote 2 AQ 10'' HDC3 copper subs 1 3500d AQ amp 146.3db on TL with stock electrical in single cab truck at 32hz RESULT: 1st place at comp, 3rd overall out of 20 cars Link to comment Share on other sites More sharing options...

So if I can get by with two alts and a good batt I'll give it a shot Run a multicell batt under the hood with two alts and you'll be fine. You can get a Battcap 8400 that would be equilivent to a pair of D3100's or get a CS9000. The CS9000 is a Cactus Sounds battery and is probably the baddest on planet earth of it's kind. They were used in most of the Street Max vehicles in DB Drag when multi's were allowed to be used. That would be a battey I would still run in NSPL since it's completely legal for me to do so. If I were wealthy that is. They cost around 2 grand brand new and finding them used is a bit of a chore. The Battcaps are easier to come by and are almost as good of a battery.
