kicker 12'' L7, i was looking at a hifonics amp cuz my friend recommends them but what do u guys recommend?... its going in a 1990 4runner that i have had for a month... also, what are some good speakers? it currently has some infinity speakers, which are crap, hooked up to an amp. im pretty new to car audio, i just know the basics, and want this to be my first install so any install tips would be great too
