Can I trickle charge while my car is on?

[loudlittlefvkus 10+ year member]

theres a car show at my school pretty soon, and my electrical system wont handle them playing that long i dont think, even with it running. can i grab a few extention cords and hook up a trickle charger to help out a little bit while im playing my system or should i just wait till after? id have about 2 hours after to charge it till school gets out, we can push it back up to a wall plug if we need, ahah

i have an optima yellow top so no jump starting right?

Trickle charger will make no difference with the car running. Either don't play full tilt or plan on doing demos and letting it charge back up before doing it again...
