Alright, I know that there are a lot of opinions out there, but I just need a little help. I just installed a JVC kd g510, and now I am looking for a single sub/amp set-up. I don't really want ground shaking bass, just enough to fill that little void. Also I want to maintain as much trunk space as I can, so a small package is a must. And last of all, I don't want to spend a fortune. I do perfer good brand names, and reliabilty. So what do you guys have in mind?
