I am planning on getting a TC-3000 15" sub to replace my current 2 Pioneer 12's. I have a Power Acoustik A2400DB amp which I think should be enough to push it, but I'm wondering in the next couple months when I can get a 2nd TC-3000 15 will it be enough or will I need to upgrade? Also, if the amp won't provide enough power would a Power Acoustik A3000DB be enough? I would like to keep the amp in that line because it matches my 4ch. amp.
