I Have a 92' F-150 for winter and I went to my dads house to store the mustang and get my truck ready for winter. I took it for a spin and noticed my lights were dimming. Now the system is my very 1st from when I was in high school.. I currently have a yellow top optima (1 year old not even) stock newer 80 or 85 amp alt. The amp is a jl 500/1 and the 4-ch. is a alpine m-300. Should my lights be dimming at such a low rms level? I have extra knu koncenptz 4 gauge wiring from the install.
I'm heading back over there tomorrow. I checked all my grounds which are connected to the seat bracket, they have been sanded down and tighten real good.. I'm curious if I should upgrade the ground from the battery to the vehicle w/ the 4 gauge? any advice would be great as this is fairly annoying. Sorry if this question is dumb but I am still learning
I figured that the pathetic alternator was the problem. Thank you for your input I will be shopping for an HO alt soon. You would think I would know this stuff allready as I am preparing for engineering school. good thing this forum has some very informative people
^ It has the good ol' 5.0.. Wow 40 amps @ idle that is terrible.. I could only find 100 amp altys at Summit racing will this be ok? I don't wanna spend a crap ton of money because this is just a winter vehicle. I did do the big 3 upgrade yesterday as deathoob recommended and it seemed to help out a bit.
lol power b@astards. Thanks rovin much better options than 100 amp altys I was looking at.. 200 amps should be enough..Since I have the head room it maybe time to step up the sound system a little bit..
