[QUOTE="MmatsDude, post: 5067958, member: 586264"] Sup guys got a new hc1800 on the front and pmd3100 on the trunk, both of them sit at around 12.4 volts, when i turn on the car my kinetik stays @ 12.6 volts and my pm stays @ 12.7 or 12.8 volts @ idle when i rev it up a little bit the voltage goes up too 13.8, if i rev it up a little harder it goes over 14 volts, but i think i should be getting more @ idle though since i have an EA 180 amp alernator, this is without the amps connected yet. i did a second test, i left the AC on and all the lights on for 5 minutes while the car was off, when i turned the car on the voltage was reading the same 12.6 and 12.8volts and the amperage was in between 40 and 50 amps, i then gave it a good rev, and the front batt pulled over 100 amps @ 13.7 volts, i guess it was charging it self back from everything being on when the car was of, the pm on the back read the same volts except it pulled less amperage. i also have 7 grounds on my big3 so i know the grounds are not the problem lol and im runnin neg wire from batt to batt all the way from the front batt to rear can i also ground the rear batt to chassis(trunk batt) to get an even better ground? eventhough im runnin neg wire from batt to batt? idk if this is normal but i think i should be getting more voltage @ idle [/QUOTE]
