Hey its been awhile since I was last active in this community. I had a 2013 Mazda 3i SV in white. Got into a pretty bad wreck and have since purchased a 2013 Mazda 3 Sport. I have been dying to change the alternator out for a more powerful one. As of lately since installing my amp and subs I have been having really bad headlight dimming at night so I decided to reach out and see if anyone has any good suggestions on an upgrade and/or procedure for the replacement.
