Official CarAudio.com Big 3 Thread

The Big three is not an end all be all to your problems.

What size wire did you do the upgrade with? You're not even close to pulling over 1000w with your current system listed in your sig.. so perhaps you have some other issues with your car.

You should take your car to AutoZone or Checker and get a free electrical system check up. They'll be able to tell you if you need a new alt or battery (most likely battery).

 
I used 1/0 awg from KnuKonceptz. I do have 14.5 ish volts running accross the poles on the battery, and it only drops about 1 v when it hits.... but it does result in dimming. Come to think of it, the lights dim ever so slightly, for a split second when I use the power windows too (without the stereo on). Do you know if Partsource does free electrical system checkups?

No idea. Try calling them on Monday.

i get the same thing with the power windows and the dimming. I thought we had the same cars, but we don't. I have a 98 Lumina LTZ. Is that normal? If you find out let me know!

 
has anyone here done the big 3 for a 01 cavy if so post pics thanks //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

 
What size fuse should i use with 1/0 gaguge wire with a 240 alternator 250a?
Yeah, that would be fine. Unless the alt make more power at higher RPM's.

I have a Ford F-250 with two batteries under the hood. Should I just make it the Big 6?
Just run two lines from the alt to the batteries and one from each of the negatives to a common spot. It would actually only be the Big 5 in your case.
