My lights still dim even though I upgraded my alternator and did the big 3, but voltage is above 13?

skip the cap.waste of cash.. 80 amps worth of fuses on the amp leaves ya 50 amps for the car... where ya get the alternator from? maybe not puttin out 130 amps except at 3-4000 rpm or so.. turn subsonic on and see if it helps a little... need bigger alternator
