that would be fine... you running another amp at all?

you should be good just doing the Big3 if that is your only amp, then you don't have to waste money on batts... depending on the car.

they are 14lbs a piece so roughly 30 lbs or so and thats the only amp i dont have the big 3 done though

do you know the output of your factory alt? I would just spend $20 on the Big3 rather than a couple hundred on batteries.

i dont off hand. so your saying i shouldnt buy batteries for a sundown 1200d and just do the big 3 in 1/0 guage

depending on your stock alt... that is what I would do. My stock alternator puts out close to 100A at idle which is about the same as most H.O. alts. Of course it only goes up to liek 145-160 amps at higher RPMs where as HO alts can go much higher but how often do you rev your car up to 2000 rpm when listening to music?

what is your vehicle?

Sorry to thread steal, but i've had the same question. I have a stock 100A alternator on a 2001 Impala. I only plan on running a DC LVL 4 on 1200rms. Would I be straight with my Big 3 already done, or should I look at getting a battery as well? Thanks for any help, Mike.

I'd say you are OK with just the big3 as well... I mean batteries are never a BAD idea but I don't like to spend money unless I have to.

I ran my VX2200D on a bone stock electrical for like 6 months and never had an issue. swapped out to a MM4000.1D and did the Big3 with an OG 300A alt and ran that for a while with no issues as well. Currently running a Fusion 2500 @ 2ohm on just the Big3 and I haven't dropped below 12.6~ yet

Haha same here man, same here. Thanks for the quick response. I'll defiantly run it until I have the money to grab up a battery. Thanks again K_Schutte. Good luck OP.

Ok cool but when I had my last setup I had hella dimming and it dropped down past 12 volts that's why I was considering two batteries

 

[ICHASEPAPER2010]

Car started at 14.2 then when playing I've seen voltage drop down past 11.5 with the kinetic in the back and stock back up front

big 3 will cure most of the issues with dropping, your talking 1200 rms watts ( 1400+ realistic potential on good electrical ) and with box rise you are prolly no where near to pushing it hard so guesstimate 1000 true output watts, if after big3 you have issues have the start/charge system tested at a part store for free.

if after that you need hc600 lemme know 90 each shipped for the same battery BNIB 1 yr warranty ( bt20 shuriken ) i ran over 2kw for sub and 1000 on voice with an 80 amp alt and 2 runs of 2 guage with just 1 of those daily for over a year with almost no dimming and never went below mid 12's.. big 3 was what made it possible or i would have need 2 times the battery storage.

dont lisin to him you need batts or a alt upgrage if i remeber that amp does like 1700 wtts witch means it draws at least 140 amp at 50 or so your car takes your and about 190 amps of current to suppley i have seven batterys 450 amp hours worth and 2 200 amp alts and with my sundown saz3500 at .3 i still drop to 11.6
