I am interested in buying a 12" Fi BTL-N2. I see that in order to buy the speaker you have to configure the speaker. I know for sure that I will be using this speaker daily. Now as far as for the ohm, P Chamfer, Cooling, HiXmCoil, & Universal. Im not sure what to do with that. Plus what would be the best amp to use with this speaker. I appreciate the help bro
