has anyone ever used the lower end speakers from mb quartz or focal? how do they compare to the other brands out there. I think the focals are poly flex and the mb's are discus series. I plan on going with a higher end alpine deck and probably 1 10"in the trunk and i would like the speakers to be really clear. dont listen to a lot of rap or anything so bass is not an issue. Also for those of you running components where did you put the crossover for the front?
