I am at a delimma now...I just got a Premier 930 HU, and the sound is out of this world...The only problem is that my JL Stealthbox with 8" W0's just can't keep up....It's just not putting out the power that I want. Does anybody have some suggestions about what to do? I am seriously thinking about selling my stealthbox and amp and replacing it with the box from subbox.net. Anybody got suggestions for what subs to use with that box? Also what is a good size amp to push two 10's?
