Dropping voltage (the best sq voltage solution)

[[email protected]]

Just want to ask la. my pioneer can display voltage value of the car. when the car is started it was 13.8. the when the ac is on it change to 13.4. then when the headlight in on it was 13.1. and when the fog light is on it was 12.8. is it will affect the sound of my audio set and is it will also consume more fuel. what is the best voltage for sq. how can i increase and maintain the voltage at peak.

upgrade your charging system... starting with the alternator...

problem still presist? mayb there is a voltage leak... so that is one hard thing to find...

good lluck...

oh ya... the best vostage for sq? i say 14.4V...

always check your battery, and buy good quality ones, non maintenance free usually lasts longer

can also upgrade wires from alt to batt to a bigger size, as well as the ground cables.

if more adventurous can upgrade your alternator to something rated higher (if your stock alt is below 100A maybe u can find one thats 100 or 110A that can fit your car)

also can add 1F capacitor in your system just before the amp.

plug in Photo conductor, add voltage stabilizer (HotInazma hyper recommended) and put capacitor to each amp accordingly hahah

thanks guys. i will try by upgrading my battery first and maybe the wire between battery and my alternator. my altenator is 90amp. my batteries already 2 years old. once i listen to songs in the car without turning on the engine and the car cant be started. when i check the battery is liquid is dried. some says that when it happen the battery is not in a good conditions any more.

battery is the obvious answer...
