I have 2 LE PB 12s on order, and I just received the wiring kit from KnuKonceptz, but I'm still deciding on an amp. The Profile CL600M caught my eye with it's high power (450w @ 2ohm), high signal-to-noise ratio (105 dB), and low price ($110 on ebay). Plus the THD of .07% is acceptable. What am I missing? The spec sheet makes it seem like a better amp than the jbl 600.1 that everyone seems to like here. A search turned up few "profile" references. Thanks.
