I bought a used box with subs in it and it slipped my eye that they weren't the same, one is an xtr 152d and the other is an xtpro 152d
the xtr is 750w rms, and the other is 2kw rms, any guesses how i would wire these so as not to blow one? Or would i be better off splitting them and running separate amps? Any information would be helpful because the research I've done is only showing similar rms

Thanks,
Dosh
