Ok thanks for the help. Any idea where to get an affordable amp for my car? 2013 subaru wrx? Also how many amps should I go for if I get oneMeasure your voltage and see what's happening. If it's dropping to the low 12s you need a alternator. If it's dropping to low 13s high 12s a battery should be fine.
