the question is: what do YOU want?? I saw a thread where u were discussing a 600w RMS amp at 2ohm.. I have an autotek SX900x amp thats nicely underrated and i believe is 650@2ohm and 900rms@1ohm.. what else may you be interested in?? I have an older JL 15W3-D4 that came with an HO box I found, thus the reason I want the HX2, itll do the job until i can get a Power HX2 15
