once you get it in there and et used to it you will want it to be louder at least thats how it was with me. The only way I would go with sealed is if you increase the box size a little bit and make it real deep. I ported mine to about 35hz but my friend got the box size wrong (I think) and dont know what it is tuned to. But I only have about 800 watts rms running to it and it rattles everything. Pretty awesome sub for the money.
