How would an amp with bass boost capability work with component speakers? I mean is it bad..good? Would the components be better off being powered by an amp without this ability?
bass boost on an amp is usually at about 40Hz. components roll off naturally at about 12dB/octave from around 100Hz, so the problem you'll encounter is basically that components will bottom out and distort if you use the bass boost circuit on them. your best bet is to use bass blockers or a HPF on the amplifier to block frequencies below about 100-125Hz from components and let the subs alone handle the bass, setting sub LPF crossovers to about 60-80Hz. the natural rolloff of both subs and components will cover any gap in the frequencies, so the overlap will make up for that, and it'll blend smoothly.

Thanks for the explaination..i get it What wuld u recommend doing for a system with just one set of components? What sort of features in an amp shuld i look for if all im going to use it for is powering a set of front comps.? (P.S. I dont have a sub yet)
Glasswolf, why do you set the crossover of the sub at around 80- HZ and the components at 100+ HZ? What happens to the 80-100 HZ frequencies? Does this result a flat response idealy?
The reason he sugest to set them apart is because the crossover point isn't an actual cut off. Both speakers will be playing those frequencies, however they will get quieter as they get farther away from the crossover point. Since you have 4 speakers instead of 2 playing those frequencies you don't need them to play as loud to get an over all flat responce. I am sure glass can explain in more detail.
yes it's called "roll off." With the gap between the mids and the subs, the roll offs will overlap and there won't be any noticeable loss. The response till remain flat and seamless. If you overlapped or met the crossover points, you'd end up with both the mids and subs hitting that narrow overlap point at the same time, and it'd feel overly accentuated or too warm or boomy.
