i've got a polk momo 10" sub that does around 300 RMS which isn't all that crazy but it's still enough to hit hard. i'm trying to sell it so PM if your interested. i'll throw in a free vented box with it. but yea man i was just like you a year ago cause i said the same thing about how i just wanted a little bit of bass, nothing too crazy. but i soon learned of the addiction in bass and found myself working up to bigger, better, and louder stuff. haha but that's just me.
