TtttttttttttiThe problem I'm having is I drive a 2002 alero with subs I have 2 12" type r subs with a rockford 2400 watt amp and a 2 fared capacitor that will hold 2000 watts I've charged the capacitor hooked the wires up to see if my lights would still dim so now I'm thinking its the alternator but oldsmobile only makes one alternator for my car if anybody knows any what will fit my car it would help.
