[QUOTE="Jeffdachef, post: 8630451, member: 650438"] here's your power chart alt pos and neg > 1st battery > pos and neg run to > 2nd battery > dual runs of pos and neg to sub amp off 2nd batt. Mids and highs amps will be off the 2nd battery as well. Literally your 2nd battery is the hub for all your amps because its a short run with lots of reserve just in case the amps demand the power, its there. Optional, ground 2nd batt to chassis. Can literally never have too much grounds imo. but thats just me, this step is completely optional and not necessary at all if a dedicated ground run helps your voltage drops. You'd have to contact your alternator maker for regulator mod options. I'd do some research just to make sure that its actually an issue. [/QUOTE]
