I have a 2010 Civic LX coupe with the base model head unit. l am trying to gather some information as I want to upgrade my audio experience but keep the stock look. I have a junk yard down the road that has a wrecked EX with premium audio parts. I have already removed the 8” sub and back dash panel. I am trying to find out if it would be possible to use the Premium audio head unit or is the wiring harness and systems completely different? If they are different can I wire up the EX’s premium OEM amp to from the base head unit? I have experience with wiring and how hard of a task am I looking at? Has anyone tried any of these?
