Hello! This question is not for a problem, but to prevent one! . I have a stero system that I recently put together, its a mess kinda, but it works great! I have 4 speakers, 1 center and a subwoofer playing at my command. My main question about my subwoofer, and getting a new and better one. My subwoofer is a Sony SA-WM250. It is 100 watts, not the best, but gives great bass! I wanted to know how much can I push it until, well, it breaks! I don't know a whole lot about this tech. The only things I know are the watts and driver size or something. (So go a little easy on me ). My second part of the question is, what would be a suitable upgrade from this? NOT TOO EXPENSIVE. I'm not going to run a professional audio setup, just for music really. My room is small, so the bass goes around better. Just ask if you need anymore information! Thanks!
