[QUOTE="Doxquzme, post: 8920148, member: 689267"] First and foremost, get an idea of what average daily drivers use on a relatively high-wattage system, like 2.5k. Second, a caveat of sorts. If you're going to use your system for parking at the local bass soundoff or playing it hours on end without the motor on, that's not what I'm recommending this for. If you're like most, and it's a daily driver that you want good and loud when you want it to be, and normal to elevated listening levels every day, these suggestions are for you. Watch this video to get an idea of what a realistic amperage draw MOST people should expect. [MEDIA=youtube]M8RisjTngt8[/MEDIA] Contrary to the order in which the "BOT" suggests upgrades, given the advances in battery tech, the best thing for a 2.5k system would be as follows: Big three w/larger battery under the hood, 2nd battery in the cabin, preferably a lithium solution, but one of these at only $99 can help a lot.
