I have not seen this set up yet, so I thought I might share it for those you who are like me and want to have a great highs and mids in your music.
This thread is not a how to install head unit and speakers as it has been covered in other threads extensively, so I am going to focus on the sound quality of the set up over stock stereo. I am not an expert in installing or car audio, just sharing what I am learning as I go through the process.

Goal: I am not looking for too much base, I wanted to have clear highs and Mids and a little of base when needed under $1500 keeping the factory look on speakers with no subwoofer box.

What am i Installing? :confused:

1. Pioneer AVH4200NEX (already installed)

2. Arc Audio XDi 6.2 (6.5") front components :D (front OEM speaker replacement)

3. Kicker CompRT 6.75" subwoofer :wiggles: (Rear speaker replacement they are slightly bigger than stock diameter)

4. Arc Audio XDi 450.4 amplifier powering all 4 speakers

5. Sound deadening all 4 doors w/ Noico 80 per LastHumanGarage YouTube guide

Microbypass for Pioneer NEX 4200 https://www.amazon.com/gp/product/B00VKQ6ECQ/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1
Amp Kit: https://www.amazon.com/gp/product/B01I56RA62/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1
Metra Axxess ASWC-1 for steering wheel control: https://www.amazon.com/gp/product/B00B4PJC9K/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1


So far I have installed the head unit using stock speakers, and the sound quality has already improved. Next will be hooking up the amplifier and all the wiring with stock speakers. Lastly i will be sound deadening the doors and add the 4 speakers. From my research the most difficult part is to make the subwoofers sound decent mounted in the doors, and I am stubborn enough to take on the challenge with no experience in installing car audios, so I guess I will find out if I made the wrong decision or not.:confused1

Thanks, sub-woofers are very small yet heavy, hopefully I can take my time with sound deadening the rear doors to make them sound clean. I haven't had a chance to work on the car but hopefully this weekend i will get them done with some pics.

I'll be interested in seeing how this turns out as well. Particularly because I had the same kicker subwoofers in my back doors until they blew. But here's the part I don't get - They were the same speakers I had in my previous car (1999 Z28) with the same amp pushing them. ONLY difference is the car (mounted lower in the wrx vs. about shoulder level in the Z) and head unit. I had a Pioneer din and half sized head unit in the Z, and factory head unit in my '15 wrx with a line out converter. Never got much volume or bass out of them in the wrx. They were awesome in the Z. Had them for years in the Z. Lasted a month or so in the WRX. Have a Crossover, etc with bass boost control. One of these days I'll run by a car audio place and see if they can figure it out.

So all stock wheel controls are still functioning with new HU?
Rear camera works just with the microbypass?

Got pictures of any installation?

What power amp were using to power them? did you wire them @2 ohm or 4 ohm. I will be sort of under powering them 85 watts @ 4 ohm, i gotta start on it this friday and hopefully I can get everythinh done by sunday. I'll let you know how the sound will compare to my old set up with a 12" solo-baric I had in my old DSM. I think the factory HU of WRX was the bottleneck of your system in the WRX.

I will take some pics this weekend, microbypass function is to allow you to use all the functions of HU while driving. I don't think it has anything to do with rear camera. Yes you can retain the steering whee controll functions.

EDIT: and when you use the ASWC the buttons for volume and next/prev song work, you lose the function for the other two pick up call, and hang up call buttons from steering wheel.

Update: The front components sounds amazing, they were easy to install and I hightly recommend arc audio speakers. The rear subwoofers did not fit the OEM speaker whole and required lots of modifying. I have not been able to make them sound as good as I hoped. If I had to do it all over again I probably would not go with this option, there is very little space in ear doors for a speaker without cutting into the door.
