[QUOTE="macsdad, post: 8643622, member: 623697"] Just please don't use a prefab ported box if at all possible. I am running sealed right now, but my sub is optimized to run sealed, after displacement, my sub is getting .55cuft, and it impresses. I am by no means an expert, but I have learned that if you have to under power a sub, actually a misnomer, you can't actually 'under power' a sub, but to get decent output, it is good to have a larger than specified enclosure. And on the other side, if over powering the sub, an enclosure smaller that specified. Just because any said sub is rated at XXX watts, does not necessarily mean that it needs that particular amount of power. Most of us will use 50% more power, some probably as much as %100 more, to create what we call headroom. The way that it was explained to me was, "You can always cut it, but you surely can not stretch it." Say that we have a sub rated at 1000wrms, I would use an amp with at least 1500wrms and properly set the gain. As opposed to having that same sub and 600wrms amp with the gain cranked, creating clipping, which leads to heat, and releasing that ole magic smoke. Then there is our real enemy to output, box rise, but that is a whole other story dude. Good luck why3zx, let us know what you come up with. [/QUOTE]
