hitmeoff Report post Posted December 27, 2009 (edited) Ok, So tomorrow I will be buying a 2010 Fusion V6 SEL. It will come with the standard 6 speaker system. I have tried to search for the answers and got a few from here. So from what I gather: - Doing an aftermarket NAV unit will disable my Sync features? Correct?- I can do 6x8 speakers and 5.25 speakers. I know two are located in the front doors, but where are the other four? Two in the read doors and two in the rear deck? Seems like everyone talks about the two in front and putting two in the rear deck/rear doors...I guess Im just confused where the last 2 really are? Are they tweeters? Could I put in a pair of 6x8s and a 5.25" component system as my six speakers while keeping everything factory look? Guess that's about all. Just wanted confirmation on the NAV/Sync issue and the location of the last two speakers. Ideally Id like to put a 5.25" component system in front and 6x8s in the rear, as well as a sub in the back. But if putting in 5.25" components in the front requires me to put the tweeters in a non-stock location, I'll just put 6x8s all around Edited December 27, 2009 by hitmeoff Quote Share this post Link to post Share on other sites
