OK, quick background to preface this build log. I'm in my early 50's and have been installing systems in most of my cars since the early 90's. In my last car, a '12 Taurus SHO, I had installed a Kenwood Excelon double DIN NAV unit (with a full replacement dash kit and iData Maestro to integrate with all the factory electronics), plus PPI amps and a 3 way CDT component set with mids/tweets in custom a-pillars I fabricated and covered in matching vinyl. After spending a full day tearing all of it out when I traded that car about 15 months ago, I swore I was too old for all this nonsense and would never do that again....

Sooooooo…..fast forward about 12 months and I happen to notice a box of NOS MB Quart reference coaxials in my garage that I'd purchased a few years ago and frankly forgot I owned. I thought those German speakers would make a nice, easy upgrade and would go along with my MK7 Golf R 6-speed quite well. Obviously, I'd need amplification to make that worthwhile, so I got an Audiocontrol 4-channel and did a simple, solid install.

The downside of having nice systems in the past is that you get accustomed to that level of sound, and I've always had an acute ear for quality music reproduction. Unfortunately, door-mounted coaxials (even the venerated old school MBQ's) just couldn't image well enough for my tastes, and I decided I'd hunt for some 3-way components. Found a nice set of used Focal KX3's and then procured some salvage a-pillars and the new install I swore I wasn't going to do again was underway.

A-pillar build:

Wrapped in matching vinyl. Admittedly, I tried 2 different grill cloth versions first and neither matched to my liking. The vinyl is almost a perfect match and looks much better, so all's well that ends well. Clearly I haven't learned to rotate my pics prior to uploading...

(That's not a defect on the upper part of the a-pillar; it's a reflection from a dirty windshield...)

Subwoofer enclosure build: This was a bit of a PITA. Though my R didn't come with a spare, I'm going to buy one and was unwilling to part with the space. I'd seen an enclosure for the European market apparently made by Helix, but didn't have any luck getting someone from the Netherlands to send me one...:rolleyes:

So, break out the resin and mat again. There's not much space in the trunk cubby, but that's what I had available. After quite a bit of test fitting, I found .344 cu. ft. internal volume and just enough depth to fit a JL Audio 8" 8W1V3. I sacrificed the ability to raise the trunk floor all the way in favor of getting enough enclosure volume, but I typically lift the floor and pull it out anyway, so I still have easy access to the amps/dsp and the future spare if necessary.

9.75 liters...and no leaks.

Final test fit before sub arrived.

Looking good. I'm driving a MK6 GTI, and I'm trying to figure out my sub solution. I'm considering pretty much what you've done, but I'm also considering building a box to replace the foam jack/tool pieces around the spare. I'm not willing to give up the spare, but I may be able to work a shallow sub (or two) if I replace the foam with a box.

Which JL sub is that? How is the bass with just one?

The sub is an 8w1v3. It’s not a banger, to be sure, but does about what you’d expect for an 8” in a small enclosure. I had to sacrifice some output to keep my trunk functional, but I’m pretty confident it’ll do what I need it to with the right tuning.

The R model has a couple inches less room in the trunk/spare area due to the AWD system. I’ve seen a number of GTI’s with an under-floor enclosure while retaining the spare; it just wouldn’t work in the R. Uber Stealth Audio makes a GTI enclosure that a number of folks on the VW Golf forums have used.

The SD-3 was actually my 1st choice, but it’s too deep. Very little mounting depth in my cubby enclosure.

Very nice work. The JL stealthbox has a shallow 10, but it looks like the 8 is actually a better fit.

Do you have any shots looking straight at the hatch, so I can see how far your enclosure sticks out into the storage area of the hatch?

No JL Stealthbox for the MK7 unfortunately, because I definitely would have gone that route!

Thanks! Admittedly, my 1st enclosure attempt ended up in the trash.

That'll happen, haha. That's one reason I'm temped to go with the floor mounted option, I won't have to mess around with fiberglass. I think I can squeeze a couple of shallow subs underneath the OEM panel without raising it up.

Doh!... still, awfully nice install. How do you like the Focal 3 way? I'm stuck between the Flax 3 way set, a Morel Hybrid 602 + CDM880 set and a Focal ES + 3.5WM set.

Yes... I am a total equipment whore...:dead_horse:

Ah. We have a Mk6, which is why I am familiar with that particular stealthbox. I honestly like the look of the one you made better anyway.

Wow. Thank you! That is high praise getting the nod over JL. Much appreciated! It only took me about 30 hours of labor to get just right....

The Focal KX 3 ways are awesome, but they’re temperamental and require some tuning. Done correctly, they’re REALLY GOOD, and I was looking for a set with a mid that had a relatively small mounting diameter and these fit that bill. If I had it to do over, I’d go with the Dynaudio Esotec 3 ways or Morel Elates. My last install had CDT ES mids and tweets and their beefy ES-06 midwoofers and they performed every bit as good as the Focals at 1/3 the price. I do like the Focal Flax as well. I just wouldn’t spring for the KX3’s.

Your work is so...refined is a good word. I can’t wait for more pictures!

REALLY appreciate that compliment. I like to modify my cars, but always try to do so in a manner that only "the initiated" would notice. Guess I could've posted a pic of the actual car...:rolleyes:
