I have a 2016 Fusion Energi SE with the stock sound system (4 door speakers, 2 tweeters in the front doors, and 2 6x9s in the rear deck). I'm pretty disappointed with the stock speakers and i didn't think the Sony system was worth stepping up to a titanium model when the Energi has so many of the other features standard already.
So i want to upgrade the speakers but keep the stock touchscreen head unit without adding an amp but i have a few questions:
1.Does anyone know the output of the head unit to each speaker?
2. Would the Polk DB651 coax speakers work ok in the doors with that much power? - 4ohm, Sensitivity:92w, RMS:6-60w
(that's what seems to be recommended on the non-hybrid fusion forums)
3. The rear deck speakers say 2ohm them, would it be alright to use a set of 4ohm Kicker ks69 6x9s?
