well now that we finally got some sub suggestions going i want to ask about kicker subs because ive been looking into those a lot lately and they seem really good. are they overrated?

also what should i look for when buying a sub? obviously i cant hear what it sounds like over the internet so what am i looking for for good sound quality? like i said i dont need the people 2 streets over to here me when i come home from school. I just want it to sound good at medium and low volume and still give me a good punch in the chest
