I'm gonna end up redoing the head unit and amp. I have a REC/NAV head unit in my car so when I do that upgrade, I'll swap that head unit into the truck. The one I have has issues as I noted before.
I'll also not re-use the Kicker amp. This time, I'll go with something else. The Kicker speakers I will keep.
As far as a sub and amp for that, I'm undecided as of now but I'll pick something later. First I have to do the car so I can swap over that head unit.
The car gets this setup:
Kenwood DNX9960 head unit
JL HD 600/4 amp
Hertz HSK 163 3-way component speakers
Focal 165 VR3 speakers
PacAudio C2RCHY4 interface
PacAudio SWI-Jack adapter
PacAudio SWI-CAN adapter
Kenwood KCAIP301V ipod integration kit
Stinger SHK241 4 ga amp wiring kit
I may swap over my Alpine 500W mono amp & Type S sub to the truck and go with something else in the car.
I'm sure there's something I'm forgetting for the car but I'll figure it out.
