hi every1, my fiance and i just bought our first new car. a 2010 jeep wrangler unlimited sport. i tried to get the upgraded radio with speaker system but wasnot able to. we ended up getting the sat radio with just the 4 speakers and the 2 tweeters on the dash. i believe that the bare stock everything. i have a subwoofer out of my old car and im not sure how to connect it. it has an optional harnes that splices into the 2 rear speakers and goees to the amp or go thru inline. i used to use inline but the stock radios dont have that right? so whats the easiest way to connect it? and if i splice it in thru the speakers how does that effect my warranty?
