Im new to the Fusion ownership community. I am looking to slowly do a few things in the new few months, first with the sound system. For being a base system the Fusion has nice system but I am a sound fanatic as everything needs to have premium sound. Has anyone upgraded their system yet? I do not want to uninstall the factory head unit as I want to keep the SYNC and I am not interested in getting the adapter to connect to aftermarket system to keep my SYNC capabilities. I was first interested in getting a powered sub and connecting to some 6*9 in the factory openings. I was not impressed with the Sony system at all as it was not worth the extra 1500$ in the Moon and Tune Pkg due to not including a sub in the system. Plus I did not need the SEL Trim anyway. SE with a little better sound and the SUN 'n SYNC pkg was good enough. What have you guys done to upgrade? To upgrade I was thinking about a Infinity Basslink powered sub and two 6*9 in the openings. If the Basslink was not strong enough to power the 6*9's I would consider getting a 10" and a JBL or Infinity sub to power it all. Any suggestions would be great. I am not looking for a ton of bass, just a decent amount. Probably do not need anything bigger than a 10" sub.
