600watts x 12volts = 50amps

depending on the type of battery maybe only safe for long term lifecycle to run down to 50% =8amphours (i forget the definition of c10 c20 etc)

excluding losses in amp and a perfect battery 50amps / 60 mins = 0.83amps min

sheeit i give up at this point because i am confusing myself and it's late.. but basically you probably only get 10mins out of that battery!

someone else feel free to correct me, im off to bed in the thunder storm now..

as i expected ahh well subs just slow you down

a1 faradpower cap will solve all your problems. the only issue you will have is that using the car at high volumes while engine is not running will mean you will run battery very quickly.
