Just kidding. Put those SOB's in a ported box. Alaxan's right, bandpass really *****. Being that you're 15 years old, I'll guess that you want it super loud, right? Well, yes bandpass is loud, it's only loud through a few frequncies of bass. Listen to one of your buddies cars that has a bandpass enclosure in it. Notice how some bass tones are a lot louder that others? Well, port will play MORE of those bass tones louder. Good Luck!
