Okay guys so here is the story, so im chillin at the work picnic and all of a sudden i hear my name for the raffle and turns our i win a portable DVD player, has all the hooks ups for TV car adapter etc, so having some fun today i wired it so the sound comes through my car speakers, (kind of a ghetto DVD player) so anyways all i have to do is plug it into the cigar lighter and then plug in the chord for the sound and walah i have a dvd system in my car.... My question though, will this hurt my battery with all the extra stress on the system, (im talking about with the car on, i know it will with if off) but with the car on will my battery die as im driving down the road with this DVD player always running off my cigar lighter, thank you very much
