Power

[Super Pickle 10+ year member]

as i upgrade my system, from the two kicker compVRs, amps, speakers etc my car is definitley running low on power, aka the lights dimming and such. Now i have read about like putting in new batteries and all, but is it that simple as just dropping in a new, more powerful battery? or do i have to change more stuff? and what is the "big 3" that i read on here alot?

thanks

the big three is adding power wire where the factory wire is from the alt to the batt and a couple other places I can't remember all of them but just follow your factory wire and add 0 gauge beside it and make sure to fuse it

and also the rest depends on the amp
