Since the day I bought my truck the sub has not worked. I've replaced every fuse related to it and still nothing. So I'm thinking it needs replacing and at the same time some upgrading. I need to keep the stock location as I use all the flood space in the back. Any suggestions? I'm looking for the best bang for the buck. I'm not worried about making my windows vibrate or the car next to me hear/feel it. I also plan on eventually replacing the other speakers and adding tweeters to the front A pillars.
