4gauge+ Extra battery= ?


Recommended Posts

My light dim a little when the bass hits and i've heard bad things about power caps so i want to put an extra battery in. Can i keep the wire that i have (4 Gauge) and run it from the battery in front to the one in back withought a problem? Also will i have to replace/remove the fuse? Thanks in advance for the help.

Could i keep my 4 gauge then? Because the wire runs under a floor panel and through the side panel of the car and its a pain to remove all of it.

car audio is just a LOT more complicated than "this amp does this power" or "this sub will be this loud". its like 2 + 2 = banana. (if that confuses you then you get the point) lol
