Re: Brief voltage drops - New alternator vs. 2nd battery vs. upgrading to 0 gauge?
As I said in the last thread, your set-up should be more than sufficient... I am at around 1600w with my system right now, on ****** stock alt, and OEM battery, with the big 3 done in 1/0. And I am fine. On bass tracks with volume up loud, I get some dimming of the headlights, nothing major, but still noticeable. However, on regular music with volume up at 30 of 35, My voltage will go from 14.2 down to 13.6, maybe 13.4 at times, but always bouncing back to 14.2 That's at idle. So how BAD is your dimming really? Is it noticeable, or is it actually really bad? Cus I know that people even have HO alts and still see SOME dimming, it's common.
However every car I've ever owned or driven, has always shown minor dimming with the windows rolling up or down. I've always thought that rather standard.
I would do your Big 3 in 1/0 (which cost me $35, not sure how you're spending $100), and go from there. The BIG 3 may just solve it for you. Maybe you will need an extra bat in the back still. And I think that if the 4 gauge is true OFC wire, that should be sufficient for a run to the distro block. Though a 2 gauge wire may be ideal, and 1/0 would be more than enough, with room to grow.
