zanekeimigdesigns Posted September 27, 2012 Report Share Posted September 27, 2012 I am planning for upgrading my alternator and batteries in my car and was wondering how do I figure how much amperage I would to power my stereo after it has powered everything else on my vehicle?

Ray Posted September 27, 2012 Report Share Posted September 27, 2012 Quick way?? Divide your watts rms by 10 That will be over but give you a ballpark 3500 watt amp 350a worth of alt and battery 2008 California state record holder 157.2 Bassrace2009 California state record holder 157.0 BassraceRollin 50's 158.7db2009 King of Cali Bassrace2009 USACi score 160.5 @ 42hz Link to comment Share on other sites More sharing options...

There isn't an exact number but Ray is right... better to over estimate than under... Then you might end up with expensive issues or extra equipment...
