How much will big 3 improve my voltage

[nate1017]

Okay so im seeing 15.1v with radio all the way down. When I crank the volume around 3/4 way up and going under 40mph alt isn't pushing out all the amps so I'm seeing drops off a few certain songs down to as low as 11.5. When I'm going 60+ lowest I've seen is like 12.2-12.3 this in return is running my amp pretty warm fairly fast and these voltage numbers are lower than I would like to see. Now I know the big 3(Installing soon) will help a bit by providing more power to be ran more cleanly improving volts and hopefully not running amp as hot. But realistically how much of a increase in voltage should I be seeing if anyone would be able to give a rough estimate? If u got any questions shoot

no one can tell u that ...the big 3 isnt a miracle cure for having.subpar electrical ....as a matter of.fact if.u do nothong.but the big 3 u migjt see worse voltage drop ..it happens to many people ...my suggestion is along.with the big 3 upgrade something else like to a better battery or a second battery or ho alt..what does your system consist of?

Like he said, sometimes the big three hurts you on a weak battery, I did the big three on my jeep. before the big 3 i was seeing 13.4-13.6 witch is normal for a jeep. after the big 3 i was seeing 13.0 sometimes even down to 12.7. make sure you either use a better batt or a ho alt with the big three..

A lot of people think the big three is the cure-all....it's deffinatly not that.

what all do you have? wattage of amp or amps, wattage of subs, wiring, and anything else. Also consider your box it could be sufficating your subs. I had that problem when I first got my system and everything dimmed when I hit bass, also because of that problem my amp got hotter because my amp had to put out more power to push the subs.

System consist of 2 SA 12's 600w RMS, Custom built box 4 cu ft, Sundown SAE 1200 amp, 0 ga Audio Technix amp kit, 14/16 ga speaker wire not sure(gonna change that out for the 12 ga AT wiring soon) and a red top duralast 650 CCA batt under the hood 130 amp stock alt as well
