josephj86 Posted February 15, 2019 Report Posted February 15, 2019 Will 2 xs d3100 batterys be good enough? I have 1 already and she's dimming my lights pretty good at full tilt I have a skar rp 4500 and a skar rp150.4 I'm running a 320 A alt
image91 Posted February 15, 2019 Report Posted February 15, 2019 A second d3100 will definitely help. i'd think it will stop the dimming. The more the merrier in these cases but two d3100s should be a decent enough minimum for that size of a system to my knowledge. Do you have a big 3 installed? What's your wire run like? Will you be charging your batteries externally at all? & how do you play the system? Might help someone more experienced to better answer
josephj86 Posted February 15, 2019 Author Report Posted February 15, 2019 I have 2 runs of 1/0 ...2 grounds and I will be charging maybe every 2 weeks I play it loud only when I'm showing people when I'm driving around I tone it down quite a bit my ears can only handle it full tilt for a couple of minutes at a time lol
josephj86 Posted February 15, 2019 Author Report Posted February 15, 2019 Oh and yes definitely done the big 3
josephj86 Posted February 15, 2019 Author Report Posted February 15, 2019 I'm running the amp 0.5 ohm and I know it's bad for the amp but it's only full tilt once in awhile like I said my ears can only handle so much bass for a couple minutes
CodyDaGoat Posted February 15, 2019 Report Posted February 15, 2019 I have a 270amp alt on 3 d3100s with 5k rms. If you can get 1-2 more than thatll help. Youll want to have a voltage meter and check on it to make sure you arent dropping too low. I suggest you top off the batteries 1-2 times a week.
L&KCUSTOMS Posted February 15, 2019 Report Posted February 15, 2019 I'm currently running a 240a alt and 4 D3400xs on with 4 RP.1500s at 1 ohm and I only drop into the high 11s after about 15-20 mins of full tilt demos. 2/0 big 3 wiring with 4 power runs. Amps are all grounded to the chassi. Batteries get charged once a week. I'm considering running a 370a alt to cut out all voltage issues along with a couple of super caps.
josephj86 Posted February 15, 2019 Author Report Posted February 15, 2019 Yes I do have a stinger volt meter up front with me I really have no more room for 3 g31s I have room for 1 more unless I get a custom box made I'm putting these batts where my spare tire would go
josephj86 Posted February 15, 2019 Author Report Posted February 15, 2019 LK that's crazy man I havent went full tilt for that long .........I've gone 5 minutes at most (1song) and I've seen it drop to about 12.4
L&KCUSTOMS Posted February 15, 2019 Report Posted February 15, 2019 joseph, the 15-20 mins isn't straight non stop song change is the only "break" the electrical gets. I've pushed it before to see what the limits were and I eventually did see low 11s. A 370alt and a supercap should cut out all voltage drop for what I do with my set up. But It will end up being more extensive than that because I'm going to be swapping to 4 rp.4500s when I rebuild next and a sub upgrade as well. So as always more upgrades coming lol
