kevin ribeiro Posted May 8, 2011 Report Share Posted May 8, 2011 (edited) alright guys i have a question about voltage drop this is what my electrical will look like for my system if i can get a 400amp alternator 2 new max AGM 200ah batteries thy weigh about 150 pounds each in the back so thats 400ah 1 95 ah in the front 6 or more runs of 0 gauge and big 3 ima b running around 8000rms or higher depending on voltage know do you guys think ill have a huge voltage drop or a not to bad voltage drop ima trying to run a SD 8000.1 its rated 8000rms at 12.6 still learning a thing or 2 guys so thanks for your help Edited May 8, 2011 by kevin ribeiro Quote Link to comment Share on other sites More sharing options...
Supercharged DCs Posted May 8, 2011 Report Share Posted May 8, 2011 I think you should be okay with that, but I don't have experience with that much power... Quote Bassless once again.

kevin ribeiro Posted May 8, 2011 Author Report Share Posted May 8, 2011 I think you should be okay with that, but I don't have experience with that much power... only 1 way to find out right hahahha ima see what it does hopefully next month ima do this build a SD8000,1 vs a DC audio level 6 Quote Link to comment Share on other sites More sharing options...

What kind of batteries? Amp hours mean nothing. 3 runs of + and - are sufficient. And with said electrical, yes, you will have significant voltage drop at full tilt. 400A charging @ 2k RPM will hold its own for a while, however. Here's my 10k setup: 320A alt 5x HC2400s 2 runs +/2 runs - Big 3, buss bars, etc. I can run decently at idle, but I can't demo for hours. Worst I've seen is 12.9 under heavy abuse before I kill it.

Neo_frog Posted May 8, 2011 Report Share Posted May 8, 2011 Eight DC LVL4 10s on two Memphis 4Ks. The 10kW come from my five 4-channels. Quote Need an install?

The 10kW come from my five 4-channels. thats pretty badass man ima run a DC audio level 6 18 on a sd8000.1d i needed to know what a SD8000.1 at 14.4 volts does i dont want to run over 9k on the sub 9k down would be nice 10k just to risky ima to far away for a recone hhahahhahaha Quote Link to comment Share on other sites More sharing options...
Supercharged DCs Posted May 8, 2011 Report Share Posted May 8, 2011 8k on one DC lv6 18... I'm interested Quote Bassless once again.

CJ18 Posted May 8, 2011 Report Share Posted May 8, 2011 Not sure about the batteries but only way to know is to do it and see what your voltage looks like and if need be add more batteries. Quote Link to comment Share on other sites More sharing options...
