Question type: General

i have a 2007 chevy tahoe 5.3L flex fuel ls model 2wd and i am having some headlight
dimming issues .  i have replaced both battery wires and put a new alt and battery and
still at night just rolling up the windows will make the headlights dim a little .  i added a
after market stereo system and anytime the bass hits the lights dim really bad  it says
that the truck alt is 160 amp do i need to upgrade and get a high output alt or is there
some kind of grounding issues that these trucks are having i also added a second
battery and isolator and  1/0 wiring for both batterys grounds and positives  just for the
car audio and still have the same problem   i noticed the issue before adding any car
audio can anyone help me that has had the same problem and how to fix it thanks

Every car will dim the lights if you roll the windows up. Especially if you try to roll up a window that is already up. It's an amp draw, there isn't a way around it unless you get manual windows or design a more efficient electric motor. Maybe you need to add a capacitor for the aftermarket amp. That will help with the bass hitting.
