Mines still the stock alternator (as far as I know, I am the 3rd owner) but I'm gonna have mine rebuilt. There's a guy by my parents house who only does alternators and has for 20 years. He told me that all the alternators you can buy at o'reilys /auto zone /advance auto all use the same crappy Chinese manufacturing and to stay away from them. And I'm just running a Sony head unit, nothing crazy by any means.
