i have problems on voltage drops when i turn on heater....is this normal???...i recently have 1 1000 watt crunch amp with a 4500...not really enough power to have voltage drops....should i get 1 extra battery for the rear?
I always wondered why that happens. Hell, my voltage drops more from my rolling all my windows down @ the same time then from playing my stereo full tilt (system in sig).Normal, most stock car electrical is poorly grounded.. When i roll down my windows my lights dim.
wow, can you find a dmm to see how much the voltage drops? Is it only when turning on the ac AND playing full tilt, or do you notice a significant change in voltage when using just the ac (w/o the stereo playing).haha...when i play my stereo full tilt..(even thoug my sub is only 220 rms..=(..)no voltage drops...just when i turn on heater or ac....sucks thoug....sometimes voltage drops so low that the car turns off sometimes...
