So, let me get this right .. do you JUST want loud bass?

lol .. I, for one, don't want anybody outside my car to hear my bass.  I could care less about SPL.  Anyway, now knowing that you want that kind of performance I seriously doubt that sealed is right for you.  Did you read those links I sent you about output being higher with ported boxes? 

No one told you to seal your box.  You picked sealed because it was close to your enclosure size and you were too lazy to understand the difference between sealed and ported.

All we told you to do was READ THE FREAKING LINKS we sent you before making the decision yourself. 

Then we said IF you wanted to go sealed that it had better be a GOOD seal. 

Sigh .. Go back and actually read http://www.diysubwoofers.org/

LOOK at the graphs and the difference in output.  COMPARE the graphs pages 8 on both Shiva application documents I posted for you.  If you are looking for ONLY the best BASS OUTPUT given your amplifier power, PORTED is probably the best for you.

*sigh again*  dude, I understand you're young, but you really need to learn to read materials, search for answers and ask questions about things you don't understand, and truly make an effort to understand -- before making your own decision.  Trust me, if you can learn that simple lesson it will serve you well.

You aren't supposed to know what it means when you start learning.  Read all the pages you can at http://www.bcae1.com/
