Tuff Stuff Starting & Charging

I have owned now two of these Alternators (Black Wrinkle) for my previous Jeep and now my current Jeep, which is a 2010 Wrangler Unlimited Sport. I wanted to upgrade the Alternator because of my SKAR Audio Sound System I am currently putting in. I tried installing the same Sound System in my last Jeep without upgrading the Alternator, but due to the Sound System putting out so much Watts and pulling a lot of power, it killed my battery at the time. I highly recommend this Alternator due to the fact that it performs great, looks great and you can add more electrical accessories without having to worry about killing your battery.
