[QUOTE="squeak9798, post: 983532, member: 555320"] Look at it this way; Even if the 2000w amp were 100% efficient (which no amp is) and your car ran a [I]constant[/I] 14.4V (which doubtful it will), simple ohms law tells us that it'd pull 140A at full tilt. And that's the "perfect world" scenario. When you are running big power like that, there is no way to get around electrical upgrades. You need power to make power, plain and simple. The new RF mono amps are pretty darn efficient. I've seen a few birthsheets of the T10001bd (rated 1000w @ 1ohm, but the birthsheets are in the 1700w range) that show them to be ~85% efficient......which is pretty much the top tier of what you'll find efficiency wise. Not many, if any, amps more efficient than that. But if your budget doesn't allow electrical upgrades, then you might aswell not get ahead of yourself and scale back your system plans now. [/QUOTE]
