Hey everyone, I have a SC'd S2K and also have about 600 watts of power in my stereo. As a result, my alternator is toast. I need some ideas of what aftermarket alternators to buy. It is not the battery, which is brand new. I am looking for something that is good but not super expensive. I tried to search and didn't find much. Thanks

 

600 watt's is only 42 amps at 14 volts. You're not running 600 watts continuously anyway so, the battery can help with any excessive current draw.

The stock alternator is rated at 105 amps. If the alternator's bad, which is easy to test by the way, I'd just replace it with an OEM one. I'd check fuses too. Pretty sure the whole electrical system goes through a 100 amp fuse.

 

EK9, my car is only driven on weekends and has 22k miles on it. Seem like an OEM alternator should last longer than that. The battery is brand new and when the car is running and you disconnect it, the car dies. I want to get an alternator that is meant for handling the stereo and the supercharger. My car is out of warranty. Thanks
