[QUOTE="Doxquzme, post: 8924884, member: 689267"] Granted (I know the math), but MOST systems, in daily drivers, up to 3K even, are rarely going to exceed 50-60 amp bursts; on average, around 20-35 amp constant current draw, burst to around 60 amps. Most cars can handle this without an alternator upgrade; with an auxiliary battery, preferably a lithium option, they will more than take up the slack/compensate. Unless one is constantly pulling up to parking lots, engaging in (who's got the bigger one) DB dragstrips, people need to think about the difference between real-world use, not the theoretical max draw based on total system wattage. That video I posted earlier is a great example of how even large systems operate on a daily basis. So, unless you are driving a 1985 Yugo (Zastava), with a 45A alternator, the HO path to support a 2-3K system is largely an outdated, old-school approach that modern battery tech has largely relegated to the latter end of the options one should consider, not the first.
