I recently picked up an fi btl from a guy in a trade that has been reconed and i am not sure of the peak watts i know that it is a duel 4ohm coil cause i put a meter on it but i am not sure of the year of the sub and he said it was one of the originals but how can i tell what model it is and year? the magnet is not a traditional monster that they all are, it is a double stacked setup and does not cover the whole basket. If you can help please do guys thanks. It has never been powered since the recone it is still new.
