My 2002 has 6 by 8s in it. Just changed all 4 about 3 months ago.

 

Same here upgraded to Infinity's Kappa 682.7 cf on all four doors. I just spliced into the oem wire harness that way everything can returned to stock if need be. Actually the door adapter is made for 6x8's or 5x7's



Stock vs the Infiniti kappas


I added an extra tweeter... cuz I love the highs

 

Oilman151 didn't you add an amp to your door speakers? I was thinking of doing that but reading up on it people are having problems getting a signal. What did you use and how did you do it?

Sorry for hijacking this thread, but I need more info...
oilman151 could you please ask your customer what thay used to get a signal for the amp and where. I was messing around back there looking for a place to tap into a line but I was unable to get a signal? Both the cd player and run off optical lines.
