Yet another "bass sounds better with windows down" thread.

Hello everyone.

So, my sub sounds much better with my windows down. The bass gets lower and louder, and i can see and feel much more vibration as well.

I've googled and read many threads on this, the reason why I'm posting is because my situation is a little different. I have a sealed box, wheras most people I've read about with this issue has a ported box.

I tend to like sealed better, for the better control and better lower frequency production (correct me if im wrong on that though). But I'm wondering if putting a port on my box would help fix the problem?

My Equipment:
Infinity 1260W 12" Sub (300W RMS)
Alpine MRP-M500 Monoblock (Puts out 300W RMS)
Sealed enclosure.

Thanks in advance :)
