Ok ive decided to get 2 10" bms but on their website it has 2 differant rms ratings one says they are 600rms each and the other says 400rms each wuts the real rms? Ive got 500rms to give each of them will that work ok? They will be in a sealed enclosure. Also are there any other sites that sell them besides audiojunkies.com? And i cant get to the lowhz website it says im forbidden when i click on the link.
