I'm going to be running a higher amp sound system (at least 1000w rms) and a UAS, zach tells me at UAS it draws 40 amps. Price for me don't really matter. I just don't want to have my daily down because of crappy parts. Thanks!

 

So I suppose there is a question in there, but you never asked it.

I guess your asking what alternators people are using and where to buy them?

I've had alternators rewound locally for more output in previous trucks I've had with stereos and airbags. It was relatively cheap and worked great, they provided output verification documentation as well. You can look up and see if there is anyone local to you that rewinds/repairs starters, alternators, or electric motors for generators, hydro pumps, and air compressors..

There are companies that sell them as well, for the most part aftermarket alts are rewound oems, they may be polished or painted but it's no different than having your stocker redone.

For amperage, you can never have to much, but take the stock alt amp rating add your stereo and compressor and there is your target number, but remember the number will be a peak amp @ a certain rpm, so pay attention to the idle rate as well if you plan to be running compressors and stereo at high volumes parked.
