the problem is I have infinity kappa perfect 6.5 components in the front "100 rms" and infinity kappa 2 way in the back "55 rms" I need one amp to rum them, I have a truck and don't have the room for two more amps. If I buy a 100x4 the rear over powered and if i get a 50x4 the front is under powered. thanks
here's an option - well what u can do is get an amp like my alpine F545 which has separate gains for channels 1/2 & 3/4 so can adjust the gains 4 ur case so it will work ...
