Heh, I know, just making a lame joke. I changed the title up, that sound a bit better?

Hey everyone, newbie member here. I was told to look into Sundown subwoofers by people that actually know what they're talking about in car audio - they said these things are good stuff. Value priced and high quality, and from what I hear the manufacturer is a real solid guy. My question is, how loud and clear are these things? I need some low end for the Polk Momo system I have in my Buick LeSabre, and after shopping around speaker brands I decided this was the way to go. But I don't want anything obnoxious, and I don't want anything that is going to require a huge box and big, conspicious amp. My big thing is keeping a clean, stock(ish) look with this system. That will be the job of the installer mostly, but just to give you an idea that size is an issue here. So, keeping in mind I don't want my car to rattle, I don't want to feel like someone is punching me in the back, I don't want my component speakers overpowered, and I don't want to 'thump and boom, dawg', what kind of speaker would do as far as Sundowns go? I just want enough to provide a clean low end to my music - I was thinking maybe 1 10" would be enough, but I'm not sure. Also, I noticed there are two different types of Sundowns, what kind of differences are there in performance? Advice? Suggestions? Tell me to sell my car, buy a Civic, and throw 4 15"s in the trunk?
