Light bulbs (in cars) are low voltage high current devices. This means that a small drop in voltage causes a very noticeable dimming. Swing the supply to a 12 volt 55 watt bulb around 12.5 to 14.5v and you see a big change in light output.
If your alternator can maintain at least 12.5 volts across the battery (give or take depending on battery electroylite specific gravity) then the battery is not going into discharge and as far as the car is concerned there isn't a problem.

Alternators (the voltage regulator) is temperature compensated. On a cold start (alternator cold) it can be as high as 16 volts for a short time falling away as the alternator heats up. That ensures the battery gets a real chance to recover and accept useful charge.
On a hot day with a hot engine the alternator may only average say 13.8 volts or lower... that's normal.
Please don't start w that...I know caps are basically useless...but my battery is brand new...so I'm not worried about it...when it comes down to the time when I need to replace the battery I will buy a kinect battery....just not now.
lol I have 1/0 gauge wire going thru my whole system, including the power wire for the amp and ground...so...I don't think resistance is the issue...or maybe it is..I'm not good w this crap.. I'm just a sub/amp guy, not electronic wiring. But at the moment, I'm saving my money for some sundown z12s...not worried about buying another battery. When I get the money...I'll buy one.
