ok I want to know which would work best in my situation. I have a sytem and want a yellow top optima battery.. But i heard the red top is better cuz I aint competing so I shouldnt have my system off witout the engine on and its not recomended to run ur system witout the engine running anywayz so I dont know which one to get. I also am goin to do engine upgradesand the red top is designed to take care of the extras. any help or opinions are greatly appreciated

yellow top you can blast your system with the highbeams on all night long with the engine not running. They're deep cycle batteries
