I just bought a volt meter to see what i rub whenever i play my music. I have an fi bl 15 on a hifonics brx1600.1D. my suv has a stock alt of 125 amps. big 3 upgrade with audio technix 0 gauge. i run anywhere from 13.4v-14v while driving around. i never listen to music when im not driving unless its a stoplight, etc. is that a good range to be in? my other option is to upgrade the batt under the hood or put a second in the back but would that help my voltage out? any advice appreciated. thanks
