Hello all. I have a 2018 Ram 1500. In my dash I have Kicker 46cs 3.5" coaxials. I just installed a pair of Infinity Kappa 90csx's in the front doors and flush mounted the tweeters in the sail panel. Right now I have a factory stereo, but I will soon replace that with a JVC M650BT. I will also be adding a Pioneer GM-D8704 4 channel amp. Because I often take people to concerts and on trips in this truck, I will likely either add another pair of components or coaxial in the back. I haven't really made up my mind on that. I know a lot of people say it hurts the soundstage but I do want my passengers in the back seat to have clear music as well, especially since my eventual subs will live under their butt 
.
My question is what to do with the Kicker dash speakers. Since they have a different impedance (Kickers are 4 ohm, Infinitys are 2.5 ohm), will it cause problems if I kept them in? The factory wiring setup has them and the front door speakers bridged. I believe the Pioneer amp will put out 135 watts RMS at 2.5 ohms but I'm not sure how the 4 ohm speaker bridged in there would affect it. Any help is appreciated. Thank you
