Headlights Dim With Little/No Voltage Drop


Recommended Posts

Hello, I am currently running a Sundown X-12 V1 D2 on a Soundqubed Q-2200.1. My volt gauge is an SMD VM-1 which is wired directly to the posts on the battery (XS D3400, Stock 120ish amp alt). The issue that I am having is that when my bass plays (even when it is barely playing at all) my headlights slightly dim. My resting voltage is 14.3-14.6v and even on notes where the voltage of the battery doesn't budge, the headlights are still dimming. I'm just curious as to why this would be?

you will notice any light dimming with minimal voltage drop. Only way to stop it is having a constant/regulated voltage going to your light bulbs. i.e. HIDs

How'd you get your batteries to rest so high, or do you mean 14.3-14.6 is with the alt running and no load on it?

yeah, sorry I should have specified. 14.3-14.6 is with the car on, alt running, and no load

I'd do the big3 see if that helps first if no, next I'd add a real cap like a Rockford because you state that you have no voltage drop.

I'm thinking you have sensitive eyes, caps discharge power a lot faster than batteries and should help stop the dimming.
