Divide currrent by efficiency to get total current draw from amplifiers. For a daily only setup you can cut the total current draw in 1/2. The resulting number is considered a safe amount of amps (or in case of battery power amp hours) to safely power your system. Remember, your car will also be drawing current, so take that into account as well.</p></blockquote><p></p>
