if your not wanting to upgrade all your equipment right now I would definately suggest just going with a ported box. As said before yor amp isnt the greatest but t strong enough for the PR's.
They are actually decent subs for the price and I think you would really be suprised with the response you would get.

Are you my neighbor NO didnt think so. And she said it herself why would she lie. And mapolley07 I got to have a place to work on my radio in plus there are several other cars with systems on my block so no one really cares and i turn it down when at red lights and when people ask. You know there is a reason to put a system in your car though.
