what kind of amps? getting rid of the cap would help, maybe throwing an extra batt in the back.

bad ground! clean all your ground's in your car/truck upgrade them under the hood clean the paint/rust were you ground at including under the hood.i had a grandam and the little tiny ground that went from the batt to the fender was well just fugly I replaced it with 8 gauge and cleaned the grounding point never had a dimming problem again
