Hey guys, I drive a 2015 ST3. The current sound system isn't bad, but I would like it to be a little better. By better I mean quite a bit louder and with more bass, but also reasonably clear and crisp. It doesn't have to be world class, but I think there is substantial room for improvement. I know some people on here have done upgrades themselves. I've never upgraded or installed sound equipment before, should I attempt it on my own or have a company do it for me? Just looking for some suggestions from people who know more than I do. Thanks!
