Replacing car battery

[Morgiee]

Hi i beleive its time to replace my car battery as starting up of the car takes longer and when tested its at an ok to replace state. however i now have a sub box with a 400w am in the car with 2 6 X 6's and the door speakers are new. Is there an upgraded battery i can get which will run the car but also sustain all extra excess power from the ICE?

Thanks

The yellowtops are meant to be the best mate I think. Or the Redtops. Thats what most people seem to use and they come with long warantees

i heard about them how do you keep the charged? do you have to keep taking the battery in and out to charge it or can irt be wired to the engine to get charged when driving like the battery in the engine?
