Big 3 easy as everyone says it is?

[JeffM 10+ year member]

I'm currently running 400 Wrms on my 2002 Sebring Sedan, and I get slight headlight dimming at heavy bass notes. I will be upgrading to a larger sub so I know the dimming will get worse, So I'm going have to do the big 3. How hard is it to do? Whenever I look under the hood I dont even know where I would start. I cannot see the battery or the alternator( the battery is under the fender). So, for those of you that were once in my situation, how did the big 3 go?

yours will be just as easy as everyone else, just more wire required than usual and you may have to drill holes and use grommets.

I would think that it should not take too much effort to gain access to the alt. and the battery. If my assumption is the truth then I should think you would be able to do it relatively easily. Good luck sir, and please do let us know how it goes.

not hard at all, even in your case. 20 minutes start to finsh on my silverado including cutting and crimping the wires
