alright so i was showing someone my jammer and i had the volume up loud and sub pounding..... watching the volts they never got below 12.75...then i drove home doing about 45 or so b/c of the roads..... i get into town and at idle it was only getting about 14.2 volt to 14.0... i do have a stock battery in that i was going to upgrade tomorrow but could this be the cause of my battery being shot and not taking a charge or is my alt getting weak?
