I drive the 4dr primera p10 of '96 and I can have 4"*6" in the frontdoors and 6.5" in the back.
A question to all infinty drivers (with the older g20): how large speakers can you put in your doors? Is it the same size or can you use larger speakers?
Also, how large are they in the back?
Why I'm asking? I want to know if and how you altered your doors/backseat shelf to fit your larger speakers...
peace..
