depending on the price of the setup you are selling i think the OP should consider it. the jl 500/1 is an amazing amp which is very efficient as it has a regulated power supply. The 12w6 v2 is not as good as the 12w7 but for the price and the size of the crossfire i think it will be one hell of a sub and it will pound hard being a 12w6. I wish you would have posted that up as i just picked up a 1000/1 for a 12w7. the 1000/1 would be an overkill for the 12w6.
