165-KBE - Focal K2 Power 6.5" Bass Extension Kit . vs .165 V30 - Focal 6.5" Polyglass Component Speaker System I was looking at both off these and not sure which ones to go with.I heard the 165 v30 but not the 165-kbe k2 and the sound was great.But i can get the 165-kbe k2 $100 less then the 165 v30 i know they retail for more then that.which one of these speakers has the better sound I'll be running one pair up front and a pair of focal 165 cvx in the back doors on a 07 tahoe with a jl hd6004 amp and a 12w7 with a Boston acoustic gt-28 amp on it in the back
