i never heard how the alpines sounded in a focus. but i just put in a pair of MB quart RSC213 components in my front doors. my only recoomendation is send them ALOT of power. my alpine deck 25wx4 rms made them clip
the jensen amp i have on them temporarily 75wx2 ( jensen watts ) makes them clip. next test is running the alpine amp on them 110x2 rms and see what happens. they sound excellent with the right power, but in low power applications. the kenwoods i bought off dan sounded better than them. imo, nothing compared to focals. but the quarts are good.
