ok after my post about 6x9s ive been told by a few that they arnt realy needed and for a good sounding sytem all you need is some good components and a sub and correct amp, so what components are good? also i havnt got a sub yet so what should i go for? want an 8" or a 10" ive got a vibe vp2 amp at teh moment but i will need another one now right? its only 2 channel and i need 3 now right? or could i run the components just of my head unit and bridge the amp to run the sub? ive just ordered an alpine head unit, the one which comes witht he ipod connection..
