car off / music on....

how long can i safely play my radio with my car off?

i have an optima red top (75 cca i think). also i have my system wired so i can just play my rears off my head unit (22x2 rms amps), or hit a switch and play my front stage also off an amp (another 25x2rms watts), or hit another switch and also play my sub (another 600 rms watts).

i figure i can safely play just my two rears off HU for at least 45 mins, but what about the rest off my amps? how bad will they pull on the battery?

i play my system (about 3200 watts total) for a good hour at a time when i'm playin ball, seems like... just go over and turn it on every once in a while to give the battery some juice and you should be able to go a long time with what you have
