Does anybody have any idea's of 4" speakers?? i was thinking about redoing the whole speaker system in my 2007 BMW 328i and add a 4 channel amp. hoping to spend around 400-500
A BMW is a pretty nice car and I think you should consider a 6 1/2" component system. A 4" set just won't produce much of the sound spectrum for optimized listening. Do you have the space for a 6 1/2" component set?
