Ok, going camping, gonna be playing tunes for everyone in a 92
jetta... got a clarion deck, 2-300watt amps, 1- 12" JL W3, 1-12"
Pioneer Bullet sub. (tossing in friends amp and his pioneer sub for
more bass)

What battery is gonna have the longest playing time.... a battery from
the local junkyard out of a massive turbo-diesel truck (quite large
batteries in those diesel trucks).... or my dads RV "deep cycle"
battery ?

My dad says his RV battery will last longer, even if it is smaller
then the diesel truck battery. He ensures me that if the RV battery
can operate his stove, TV, lights, refridgerator all day when he is
out of propane, then it can handle the Car stereo for 2 nights at 7
hours a night.


any thoughts?


thanks
