I've just ordered some Infinity Kappa 6x9's, but afterwards I read about the impedance. Apparently you shouldn't run them through the head unit and they need a separate amplifier, but Ive only got a two channel amp which is built into my sub box. Basically, aside from the sound quality suffering, what would happen if I ran the 2ohm speakers from my 4ohm headunit? Am I going to blow the 6x9s / headunit? Also, if there is no alternative than to have these amped, does anyone know if its possible to remove the 2 channel amp from a Fli sub/amp box and just use that temporarily? Cheers, Mike.
