ok new question recone a tc9 with nightshade soft parts to a 12" or a re ch motor with fi soft parts to a 10" or recone my hd3 10 into a 12 and run them.
if you already have the hd3s like you said via pm bro, recone it and run the pair, will take some good power.
Otherwise, i'd do the re and try to find another to go with it.
