so a yellow top makes a difference? my lights dim noticeable at idle, i was going to throw in a 850cca yellow top and keep the stock alternator when i added my alpine 5 channel. do you think the extra amperage from optima alone will keep my lights from dimming? the stock battery is only 600cca, weak. i had a 1200cca bulldozer battery in my tundra, i could turn on 4 hellas, headlights, foglights and run my alpine headunit and amp with the engine off... when i turned the key the lights barely dimmed from the starter draw. that battery kicked ass03Carbondogg said:Yeah a yellow top will help a lot! They're only about $80 to $100 too.
cool, i'll get the yellow top and look into having the alternator rewound.03Carbondogg said:Yeah it should help out a lot. If not you can also get your alternator rebuilt too. You can usually get that done for about $20 to $40 around here.
term = regulated power sourceEisenfaust said:If you dont want light dimming get a yellow top but also...buy effecient amps. An amp with good effeciency and I forget what its called...when they put out set amount of watts at a specific voltage. I cant remember but here is an example and maybe someone can spit out the term
My xtant 1001d, puts out 1000 watts....at like 11.4 volts....14 volts....17 volts. My RF BD 1000 puts out more watts the higher the voltage goes...therefor draws more power and causes the lights to dim alot more than my xtants ever did.
