Voltage Drop BIG TIME :(


Recommended Posts

Do another run from alt back and I would do a ground run at the very least from alt case to battery negative in rear.

ok... now thats a new one for me... getting the ground from the basket alt... but if it works it work... last question do you guys think i still need the other battery?? or should i just try with the wire and see what happens???

What is your voltage difference at the alt verses at the amp? If is over .5 volt then more wire is a must.

i have never checked but i do a sum the same since the front battery and the back battery have the same voltage, and the amps are about 2 feet to 4 Feet away from the back battery all running in 4 Gauge wire since they are short runs, just so i dont get no one confused and say its to small of a wire they are only carrying 80 Amps on 3 amps and the other 2 amps carry 50 amps, since i have a total of 5 amps... back to the subject i haven't check so i would have to get back to you on that one

sometimes 11.9 on High notes of bass (dont know why, since the subs dont move that much lol XD :noob: )... any help would be appreciated

I've noticed that the sub moves MORE in the upper range of my box...

yea i still dont have a clue why since the bass it makes is pretty crappy, and it dont even move that much air

adding more runs will increase it a little, not much, but sounds like you need more reserve compacity, since you are drawing more power than your alt can make. Need more batteries to matain a higher voltage.

yea could be, im just a little confussed at what should i do :wacko:, so you think another D3100 might fix the problem?

i dont mind my voltage going to 12.5V since im running the JL Audio HD amps and still produce my actual watts at that voltage says JL Audio.. but i just dont what my batterys getting Fucked up, since i notice my resting voltage stays any where from 12.4-12.8V when the car goes to sleep :D ... I also think my alarms eats up alot of power i dont use the car that much only on weekends, the only good thing i do is charge up my battery's almost every weekend with a XS power intellicharger :)

once your below 12.9 or so you are on all battery power alt is maxed out. So i would add another D3100.
