ok i am looking at the apline spr-17s 6.5 componets and the rockford fosgate t power series 6.5 comps, i am debating on them or if i could get away with it buying some HIFONICS ZXI65C 6.5 comps, now it would save me a whole lot buying them then the others and would be great since im on a buget but im not sure if the hifonics are any good? would they be fine or would i have better speakers between the other two? thanks
