I noticed my voltage when I go to work in the morning is 14.5 on the way home it was 12.8, I am doing a stereo upgrade and the total wattage of the system is 2800watts. I bought a HO ALT but now I'm concerned my voltage will drop down like with the stock one because it is pcm controlled. Is there any way to keep my voltage at least steady in the upper 13s. 12.5 or 13 will not be good once the system is on. I don't want to wreck my amps with a low voltage drop. Anyone with knowledge of this that would be great
