Hey all, I have a '08 4 door wrangler sahara and need help with upgrading audio system. I'm completely new to audio so bare with me. Everything is stock and I'm looking for more bass but, not looking to lose storage or row of seats. I would like to know any suggestions that would fit in same spot where the Infinity sub is right now in the trunk. Or any other advice on how to upgrade the current setup with other speakers. Thanks for advice!
