Possible electrical (or alternator) problem? Options

[travisxcore]

I don't know if its just cause this is an older car or if my alternator might be going bad but does anyone elses interior/headlights flicker and get dimmer when their electrical fans cut on? Or when I have my subs on (not really that high powered either) my lights dim. I know when I have them up (I have a 1500 watt amp w/o a cap) that'll cause it. Just wanna check to see if I should get a new one.

you can upgrade your wiring if you are willing to take the challenge most don't. a capacitor honestly is not worth its money, all it is is an additional semi battery that forces your system to charge both and try to keep up. best and complete recommendation, is optima yellow battery, better alternator and upgraded wiring if you can. cap, not a big deal, but is worth a try to test how it affects this system. if it is beneficial keep it if not remove it. it is based on combination and how it works out. downright, nothing beats a good battery, always optimal to have an alternator to keep up with how much you are drawing power, and its nice if better wiring can flow that power much better through. not much more to say.

Thanks for all the information man. I think that upgrading my wire is definitely good path to take along with the alternator because I'm sure after 16 years (and 4 years of a high amount of power from the amp) the wires are deprecated. What all would I need to do?
