Voltage Drop

[feelthebass33]

I've got my subs and amps in only at this point. Equipment in sig. My amp gains are at 40V A/C @ 1 ohm. I have 6 75ah batteries, big 3, 2 runs of 1/0...Etc. I still get pretty bad voltage drop at full tilt. What gives? I have a powermaster 200A alt...but I had to have it rebuilt a few years ago. Had it done at a local shop. Maybe they didn't rebuild it to 200A? Or do I still not have enough battery reserve? Someone please help on what I need more of. I want to push a LOT more power so how much battery reserve do to need for like 8k?

id say have that alt checked out for amps

but put another alt in there

200A probably isn't enough to supply that whole system and handle keeping the batteries topped off

id say a 200a alt isnt enough for 4 18 level 4's w lvl 5 parts, and keeping them batts going, but thats My Opinion

everything looks good except alt, as stated above 200a (max)isn't enough to use the system, keep batteries fully charged and maintain car's basics. Those 2 3000.1's suck enough juice alone.

So how much output do I need from an alternator? I can only do one because of my motor. And how much battery reserve do you think I need? Or is what I have now enough, just needs an alt to keep up?
