When you say equal to the d3100 do you mean have the same CA or Ah?
-
Well one shuriken sk-bt120 has about twice CA
-
I'm not planning on running my system when the car is off I just want to stable the voltage drop
-
Ok thanks, is there an CA or Ah to RMS Needed conversion? Like if I have a 6000w Amp draw (4000wRMS with the amp efficiency factored in) what CA would I need? Or is there a certain Ah I need?
-
This is NOT a vs post sorry about that

To start off, I'm new to batterys! I replace my car one when needed but other than that there all the same. It has been suggested to me by some fourm members to use 2-3 XS Power D3100 batterys (if space is permitted). Now as we all know the D3100 has 1360CA, 110Ah, and a size of 12.99" x 6.81" x 8.43". Do I went online to price it and I found it for around $370. And just out of curiosity I looked at some other battery's to see what elts there was. I found a Shuriken SK-BT120 for $81 cheaper, relative same size, 1240CA larger, and 10Ah larger. Now this is now a vs post but I'm confused why its cheaper? I just want to know if there's something I don't know about the D3100 that makes it better it there another thing I'm missing other than CA and Ah?

Ok thanks for the input
-
I found that an class A/B amp has around 50% eff and a class D amp has arround 70%; in that case i would need a single 525A (536.9 to be exact) alt. or two 275A Alt.s .... dose this sound right for an 8000w peak system?
-
ok, i have two 18 foot 1/0 awg wires should i:
a. Run one as a Positive from the front Batt to the Back Batt(s) and run the other as a Negative from the front Batt to the back Batt(s)
+Wire ground is always better than a Regular Frame Ground
-Current draw (360.9A) may be too much for the single 1/0 awg (350A) Positive
b. Run both as Positives from the Front Batt to the back Batt(s) and just do a regular frame ground
+Dual 1/0 awg Positives should provide more than enough current (up to 700A) for the 360.9A needed
-Regular Frame Ground may not be enough
-
i have heard about running the two batts, amps, and the alt together in a close circuit so there is no interference with the main batt and alt? should i do that or just run them together as one big system?
-
should i run the wire/Alt./batt as a separate system than the car, or run them together? And should i replace the stock Alt. or just add to it?

Dose anybody know the Efficency of an class AB (T8004) and a class D (T20001bd) amp?
So above he used 80%, let me know if this is the correct math?
4100w RMS / 0.80(%) = 5125w Needed to get the RMS
5125w / 14.2v = 360.9A
360.9A + 60A for system = 420.9 Amp Alt. needed
So for this system (@80%) I should replace the stock 130A Alt. for somthing like a 425A Alt. ?
OR what do you guys think about running a compleat sepreat system? I could run a 360-375A Alt. in addition to the stock 130A Alt. and just run a compleat separate wires back to dual battery's ?
Which would be better? Space is limited so I could only run 1 or 2 extra batteries?
-
Well should I just get like two Yellow Top batteries? As big as I can fit?
-
How big should they be? CA? CCA? Do Thoes matter?
-
So I should be looking at my Amps RMS or Peak Watts when trying to dice an Alt.?
4100w RMS / 14.2v = 288.7A
288.7A + 60A (for the electrical systems) = 348.7A
8200w Peak / 14.2v= 577.5A
577.5A + 60A (for the electrical systems) = 637.5A
So should I look for a 350A Alt. or like two 325A Alt's?
And what size batteries should I get for the back?
-
I have a 2004 Ford Explorer and I putting a large system in it. I have the stock 130Amp Alt. and the stock batt. I have two amps and combined they are at least 2400w RMS and will possably be as high 4100w RMS. I did the Big 3 upgrade and I'm wondering if I will need a bigger Alt. and if so how big should I get? Also how many extra batterys should I get and what size amp or amphour should they be? Size Isant unlimited so the smaller the better so if I can use one larger vs two smaller than let me know. Thanks

It was a general statement lol

Plz no bias brands I don't want this to be a VS post, I'm just looking for factual pros and cons to each setup
-
I'm talking in thory, in a perfect conditions, no back pressure on the cone, no distortion from tha amp, all perfectly sized enclosures, probily T-Lines. In thory how will the output change, if you are going to criticize my post then don't comment.
-
I have read that one 15 is the best because it can hit the lower hz cleaner without distortion but it takes longer to move their for there is a lag and possible distortion, however if you have enoughf power to the 15 it will become tighter like a 10" or a 12". Is this correct?
-
Space is not a problem, this is what I'm looking for, can anyone confirm these and feel free to add to them as you wish. Just rember this is not a VS. post.
2 10"s- they will be a tighter sound but it lacks output in the lower hz.
1 15"s- has excellent lower hz output but lacks upper hz out put.
For anyone who wants the cone displacement (SA*Xmax) they are
2 10"s 245in^3
1 12" 442in^3
2 12"s 360^3
1 15 702in^3
Now I am pritty sure that these numbers ^ are directly related to the SPL output but I'm not 100% sure

Lets start this off by saying that this IS NOT A VS. POST!!!
I have a Rockford T2000.1bd and i need to push some subs off it, now i haven't decided on a brand and i don't want your input on what brand you think is better. I am looking for Factual Correct info on the setups. I Have narrower my search and i'm looking for a Loud n' Clear setup.
These are some options:
2 10" 1000w RMS Subs
1 12" 2000w RMS Sub
2 12" 1000w RMS Subs
1 15" 2000w RMS Sub
Can anyone give me pros and cons to any of there setups? Rember i dont want personal bias and this is not a VS. post.
Thanks

Ok thanks for the imput

So I'm on the mechman website, I click HighOutput Alts- Ford truck- Explorer- 4.0L V6 SOHC- and then I'm stuck with the year.... I have a 2004 but idk what the rear cover there referring to is? The options are black or gray? And they both lead to a different recommended alt. where is the "rear cover"?
