Sorry didn't see the Mach 5 forum. I put this in the speaker forum as well. Anyone tried these sealed? I don't want to take up a significant portion of the back of my Tahoe since I have baby things. So has anyone tried these sealed around the 2.5 to 3 cubes per sub range. Just so you know they won't have a ton of power on them. Just the sub channel on my Kicker ZX700.5? I'm trying to get something that is a louder and lower the JL12W3's in there now. I'm moving those to my Camaro.
