ok so i have now heard the 460 system in a 04 v6 and the sound is tons better than the system in the ol fox. so im wanting to know if it is possible to get the 460 in my car. my 93 fox has a head unit that pushes some power to the speakers. so will i need the 460 amps? or can i just bolt the speakers in. the rears are 6x8 correct? which could be made to fit. what about the fronts size? i just thought it would be a cheap upgrade thanks.
