If your looking to spend $250 then Walmart is your best bet. If you can spend about 150 more then Ebay is your friend. I bought (all brand new) a 12' kicker L5 enclosed in a kicker box with a rockford fosgate 600w RMS amp that also came with a amp kit for only $408 shipped with insurance!!!
def some cvr's ported like someone said....for the money you can't beat those subs, i had two 12's in my crx and it literally gave my friend a panic attack...haha, i know that sounds like noob story but it really happened.
