2016 premium, love everything about this car except when I have to drive for more than 10 minutes and the head unit functionality with my iPhone and speakers drive me crazy! I can't comprehend how such garbage was put into a modern car -- so I'm going to change it.
First order is to replace the head unit. I'm looking to install a 4200NEX -- going to have a custom wiring harness made so I can easily have my rear camera and console USB work, as well as a Maestro RR steering wheel adapter. This 4200 will work well with the 2 channel pioneer d800 amp I plan to install under either the drivers or passenger seat.
Next is the speakers. Looking at Hertz HSK 6.5 components, planning on hiding the passives behind the dash if I can, otherwise in the door. With the amp I'm obviously going to need to run new wiring.
Lastly I'm going to do some sound deadening, a combination of damplifier as well as mass loaded vinyl.
1: does anyone know if it's possible to run RCA inputs to the amp and then front speakers, and have the regular wiring from the HU power the rears? I'm not really interested in replacing the rears, at least right now, because i never have rear passengers; however, I've read not all head units will let you use both wires and RCAs.
2: anybody know a good place to get a custom wiring harness made?
3: anyone have any info on the front speaker mounting depth and speaker hole diameter? The HSK is a large 6.5 and I'm trying to figure out if there's even enough space to fit it -- I'll obviously need an Mounting ring to give myself more depth.
4: anyone have experience mounting larger tweeters? Will they fit well in the stock location, or do they need to be mounted on the pillar? I'd rather keep them in the stock location just for a cleaner look, although understand this might now be possible with a bigger 1" tweeter.
5: where's the best bang for your buck locations for deadening? I'm not feeling up for taking the seats and carpet off and doing the floor, so I'm leaning towards just the 4 doors; however, if anybody has any experience with other locations that significantly reduced road and/or engine noise then I'd love to hear.
I think that's it, thanks for any help!
