I have just purchased some 100 w alpine coaxials http://www.caraudiodirect.co.uk/alpine-sxe1325s-p-2985.html?cadid=2542d9012afb26e04d5f46db50187e48 for the front, a 300 W kicker sub and a vibe blackbox 1 amp. Would it be possible to run both the sub and the speakers off only a 2 channel amp or is that jus foolish? Thinking I might jus run coaxials off HU as its 4 x 52 W anyway. What do you guys think? Thanks
