OK i have a question i am thinking about getting new deck to replace my factory one. I do not know a ton about them but have installed them before in a few cars. One issue i ran into was with my wifes grand caravan. When i put a cd player in it the rear speakers would not work well with the new dick because they were amplified with the factory deck. (hope everyone understood that) So i had to replace the rear speakers as well. OK so down to my question am i going to have this issue with the fusion as well? Or will i be able to just put the new deck in and be done with it. For right now the factory speakers sound just fine to me so not looking at replacing those anytime soon. I am thinking about adding 6X9's to the rear deck lid but will get a 2 channel amp to run those.
