Electrical Confusion

[whicks0731]

If I'm trying to run 2600 watts, how much power do I need from my alternator/batteries?? Right now I have a stock 70a alt, stock front batt, 4 gauge big 3, and about 100 ah of agm batts in the trunk. I don't know much when it comes to alternators/batteries, and how much power a system requires from such. Any help will be appreciated. I'm just confused and need some direction. Thanks.

What are you basing your 2600 watt estimate on?

Please post make & model of all equipment (speakers & amps).

The real deal. I find this calculator useful -> http://www.bcae1.com/images/swfs/systemdesignassistant.swf

You will need a H.O. Alt capable of between 150 & 200 amps output. You will need to upgrade your Big-3 to at least 1/0 wire. At least 1/0 wire from Alt to rear batt & distro.

I am a EE, but not a high-power expert, so wait for others to chime in as well.
