I've got a question. Im redoing my teg's system with alpine SPR's (6.5" components in front, 6.5" coaxials in back) and a pioneer 6400 head unit. What im wondering is, without a seperate amp powering the mids and highs, will I be disappointed with the sound output? or will the measly 50w X 4 from the HU give me enough power for a setup like that?

also, if I put in a single amped 10 or 12" sub, would that just blow away all the (un-amped) mid's and highs if I cranked it?
