Today i just noticed my lights do dim quite a bit when i pump up the volume. How can i determine how many volts is going to my amp?? I think i need an HO alt because im sure my stock one on my little focus isnt much.

measure the battery or the power wire going into the amp with a DMM

my lights dim on hard bass hits but that is because my voltage is dropping from 14.2 down to 13.7 and back up again. its not bad because it isnt dropping lower then 12.5
