Re: Need input on alternator replacement

most models offer two different amperages depending on whether you get the base model or the top of the line model with all the gadgets.

I recommend Alternator | Car Alternator

base model but with additional components to draw on the amp, so you'd want to replace it with a higher amperage alternator to cover the additional load

Re: Need input on alternator replacement

you could check other aftermarket websites, can't think of any off the top of my head, but I'm sure there's one out there that would offer an alternator with higher amperage

Re: Need input on alternator replacement

why not have it rewound and a new pulley on it?

Ever hear of the big three?

Here is a PM I Sent to someone else with similiar issues.

Lets get down and dirty here. What causes the lights to dim in your car and give you the impression that your Battery, capacitor, Charging system is not adequate? Your amplifier must share the vehicles one power source; One Power source, aka, one source that creates electricity for ALL components to use; the headlights, the ECU, HVAC, etc, etc. If you are using a stock alternator you need to keep in mind that the manufacturer of your vehicle used the minimum Amperage rated alternator possible. I mean, why wouldn’t you? Sure it may be a difference of just, say, $5 in production costs for them but if you put out 30,000 cars in a year, just like yours, that is a savings of $150,000. Right? So, first off let’s not assume your charging system is adequate for a 5500W amplifier that pulls, at peak voltage, what, 80-90 Amps? MOST car alts are rated for 80 Amps with peaks at 90-100. See where we are going here?
If you add a capacitor, the Alternator Must charge that too. Adding another Battery? Why? Unless you are trying to increase your “key off” play time, it is just another component the Already taxed alternator Must keep charged.

Your BEST upgrades, especially the one **** is helping you with, is to virtually eliminate the current restrictions in your system.
*DO The big three, the less resistance the more current can flow. Focus especially on ALL Ground Connections. EVERYWHERE in the car, including the Amplifier.

*Have your alternator tested under load and under max output. If it is inadequate, buy a new one or have it re-wound. If you are going “big time” I would suggest you get in touch with Excessive Amperage, Excessive Amperage, Nathan Peddicord is the owner, founder, and only employee so he is able to keep cost down. And provide kick ass service. A LOT of hi end competitors use him for a reason.

*Ditch the Capacitor. It is a car audio Myth and is a waste of your systems electrical system. There is NO reason to have it. NONE. NADA! Sell it to some other fool.

* About your Optima Batteries. While they work, and are just ok. There are MANY different Options available. IF you want to have a proper battery for a giant sound system. Unfortunately Optima is not the best way to go.
-The yellow top is designed for deep cycling and cranking. AKA it will last longer but not provide a Peak amp output in the bursts your system demands. Think of it as “slow.”
-The red top is designed around starting your car, it provides a Massive Kick to the system which is great for large engines, and heavy, immediate current demands. If you are going to use Optima Brand, you should be using the red and not yellow.
-Want key off time? The blue top, For Marine and RV use, is in it for the long run.
Now, with that said, if you want to get really serious about a battery designed around the Stereo system first and the car second, then you NEED a Kinetic Brand Battery. The previous statement sounds funny, BUT, it is the truth. Go check em out at Kinetik High Current Power Cells.

Hope that helps solve some of your questions and dispels a few myths that run rampant around car audio.
