ok heres a question ive been wondering for a while that i hope someone can help me with... I have alot of electrical devices in my '00 max: underground lites, neon rods, footpedals, washer lites, subs and i jsut got two screens taht hook up to the lighter outlet. well i have always been afraid to leave my system bumping when im hanging out somewhere because i dont want it to kill my battery. well now that i have these screens i was wondering if there was a way to power up everything to a different battery, like if i bought a new one. Could anyone give me suggestions to a way to use my electronics without killing my batter when the car is off???!? please help!!

 

try the audio/electronic section.

 

so you're trying to run everything off of annother battery when you turn your key to the acc position? honestly, theres no easy way around it, id just get a voltmeter installed in your car, and keep an eye on it when youre running everything off of your battery, if it dips below 12V, then run your car...if its an automatic, get an autostart installed, i think some of them have a low voltage protection device that automatically starts your car when the battery gets low.
otherwise the only way i see doing it involves a good amount of work and probably a good amount of money

 

ok i guess ill get a automatic starter....itll coem in handy anyways, ill look into the auto starters now, thanks again.

 

i'm telling u post in the electronics section. theres ways to put batteries int he trunk and have them charged by ur alternator when the car is running. they know how to do it.
