Ok so even with my old setup of like 400watts i had some dimming issues, even after big 3. I am upgrading to around 700watts and am gonna upgrade the stock battery to maybe something like a kinetic hc1800. Do you think this battery alone with the stock 90amp alternator will be enough to handle the system and all the cars electrical or should i keep the battery i have now and throw the kinetic in the trunk to just run the system alone? Or should i have my stock battery run the system and the kinetic under the hood to run the car?
