Aftermarket Amp/Sub/Speakers with Factory Head Unit
I just purchased a 2011 JGC Overland making this the 4th Jeep I've owned. With all my Jeeps I've always installed an aftermarket stereo, speakers, amp and sub. This time around I'd like to only install the aftermarket speakers, amp and sub that I had on my previous 2005 JGC. Can this be done while still retaining the factory head unit? Would I still be able to adjust bass, treble, etc through the factor head unit? Is a factory sound processor needed? I don't want the factory head unit to somehow reduce the sound quality of my aftermarket speakers and sub. Any insight into this would be greatly appreciated.
