I've done some research and am still undecided on what battery to get. Some people say get the yellow top, even the guy at the electronic store said go with yellow top, some people say its a waste of money and it sucks. On here someone said go with a kinetics battery. Some say its good, some say it sucks as well. I'm stuck. I want a battery that will last with the car off with the stereo playing and no die after 20 min and still start the car. I want to later get some better subs in place of the stock ones, I do want a big bass sub set up but I dont like how its take up most of the trunk space so I'm sticking with the stock subs location. Any high performance battery you guys recommend? I need to replace mine so It will need to start the car after playing the radio, not just for the system to play with the car off like an add on....Unless I have to go that route, I would prefer not having two batteries and have to upgrade the alternator. Well whatever you guys recommend throw it out there
