Yeah I can help, teggyls.
Some things you can do to eliminate dimming:
-Have your alternator beefed up.
THIS GUY is the man at that service, he's in Riverside California. An old roommate of mine bought a monster ass alternator off him for his CRX's system. It put out like 150amps. But he can improve stock units, too.
-Aftermarket battery, like an Optima.
-Capacitor, but you'll never be able to jump start your or anyone else's car again, it'll explode.
-Replace/upgrade your factory grounds, they may be corroded on an older car and not doing a great job anymore. Hmmm, now that I think of it, this is something I should do. :rolf:
-Stop using amps that draw more amperage than the factory electrical system to able to supply.
Which is about 100 amps max.
