2018 Subaru WRX

Next is the performance. I have the CVT version so there's definitely a limit on how much power I can add without having issues. I had a CVT Cooler installed, COBB turboback exhaust, COBB intake, Process West intercooler, COBB electronic boost solenoid control, and COBB accessport for tuning. I had the car tuned at Metro Performance of SoCal. Other items I have that are not yet installed are Process West charge pipe, EGR/TGV deletes.

Next is the interior/audio. So the interiors on the WRXs look pretty cheap so I wanted to upgrade it quite a bit which includes removing as much faux carbon fiber and chrome as possible. I added a few bezels that were wrapped with leather and red stitching to also give it a better look. All interior lighting was upgraded, and I purchased a dash mat to help with reflections from the mids/tweets.

The audio consists of the following:
Pioneer NEX-2440 headunit

MiniDSP 8x12 processor

Arc Audio KS2500.1

Arc Audio XDi 1200.6 (tweets, midrange, and rear mids).

Arc Audio XDi 450.4 (bridged to midbass).

Hybrid Audio Unity U3 mids in the dash.

Hybrid Audio Clarus 6.5s in front doors. 

Hybrid Audio Unity tweeters on a pillars.

Hybrid Audio Unity 6.5s in rear doors.
Sundown Audio SA-10 in ported box tuned to 32hz. IDMAX 12 is on standby!

A bunch of sound deadening was also applied since this car is a rattle machine.

It was pretty difficult to find a place to mount the controller for the MiniDSP, after some luck I found the perfect spot and it fit perfectly. It slid right in along some plastic slits so tightly that I didn't even have to glue it or anything, however I through on some hot glue anyway. Also found a great spot for the remote bass knob. 

 

Thanks. I have to try and get some more tuning for this weekend. There's an SQ comp in San Luis Obispo and I'm going, not sure if I'll compete or not. 

After hearing a few SQ competitors vehicles recently, I've noticed that something I'm missing is dynamics and punch. I've decided to try out a couple of things to make the install more stealth as well as possibly helping with dynamics and punch. 

First thing was trying out another sub setup, 3 Dayton Audio HO 10's sealed. I added the same amount of polyfill to each chamber to help make the enclosure seem larger. Definitely an improvement over the single 10 ported, the subs sound super clean and I have all the volume I'll need. 

Secondly, I picked up an Arc Audio XDi 600.4 to replace the 450.4 and bridged those to my Clarus 6.5 midbass in the doors. I haven't had any time to tune or anything but I should have plenty of power for those as well. Also picked up a roll of foam to possibly help with some resonances in the doors. I haven't installed that yet. 

Lastly, I wanted to make things a little more stealth with the tweeters and I wanted to match them more on access with the Unity mids in the dash. Now the tweets and mids are on access and I'm hoping will anchor the center stage better as well as provide some good dynamics. The tweeters of choice are the Dayton Audio ND16FA. I needed something fairly small to fit in the dash with the mids. Once again I haven't tuned anything yet but I'm hoping it works well. 

I also wanted to experiment with another tweeter mounting position using the Hybrid Unity tweeters in their housing and just mounted on top of the dash grille. This won't be stealthy but I'm interested to see how they sound in this configuration. I'll try the Dayton's out for a bit and then swap them out.
 

And the 2nd tweeter setup.

I was also thinking IB would work well but it's pretty permanent to do it right.

I had pretty good results in my 2015 WRX going IB. I have an IDMAX12 I'm not using but I think I'll get another one and end up going IB. It's not that permanent of an install actually, in the last WRX I had, I was able to get everything back to stock pretty easy before I traded it in.
