2018 golf R - upgrading "Premium" fender audio system


Recommended Posts

 

Latest progress was cutting out the top of box using the template from last week, checking fitment 3 times over;

 I then used some maths to locate the exact location of the subwoofer cut-outs;

To keep in mind:

 

There will be another layer of 'beauty panel' on top of that box in order to have a more flush look with the subs - I have not attached the top of box yet because I need it to make that second piece aka locate the subwoofer holes. I do not think I will attach this to the box, instead I will use magnets to secure it to the box once everything is installed. This way, if ever I remove the box I still have a sort of false floor if I need.

Looking damn good! I'm loving how that box fits just so in there. Good work so far! 

Thanks! been working hard! I think the box is the longest part since it’s a lot of complex and exact cuts. Also want to groove the sides so I can cleanly tuck the carpet in the groove for a great finish.

 

I’ll also want to use some caulking on all the interior corners of sub box to be sure it’s all sealed - suggestions for caulking type inside box?

 

haven’t decided where to put the Dayton terminals yet - either right in center of the back wall of the box or on one end of the back wall. Leaning towards putting them on the end (passenger side) 

 

also any way for a moderator to move this thread into the build section? Started as a gathering of info but became the actual build thread lol

I'm going to use this

It's what my cousin recommends, and he's an industrial waterproofer by trade, so I trust his recommendation on some legit, industrial caulking

nice! Can’t find it near me here in Canada, but did find an equivalent one that should work just as well;

It’s the same brand and also polyurethane based so should give the same performance. I will be letting it off-gas for at least a few days before putting subs in the box for sure.

Some more progress this afternoon - I cut the very top piece which will go above the sub box, no photos though as I just did it to be able to copy the profile of the sub box itself, so I can install that piece on the box itself (hope my explanation makes sense LOL)

 

With that, I had to also make my lower amp rack to ensure everything fit together well...I LOVE when a plan comes together image.gif.edec4068f2233ceff14218847d3963f9.gif

 

Some photos of the amp rack - using 3/8" HPDE, this will be the bottom layer of two layers. I cut it to fit in back of sub box and follows contour of trunk bottom.

?hash=4d1a9a46bc6b2557cf9da25baf4293e2

 

 

 

 

Once I was happy with fitment, I rounded over the top edges all the way around. I then marked two locations and drilled through the HPDE AND sub box tab (the floor piece which sticks out 2 inches in back of the box) and will be putting threaded inserts to basically keep the two fastened together with M10 bolts (no photos of that yet)

 

 

 

?hash=4d1a9a46bc6b2557cf9da25baf4293e2

 

 

 

Let me know what you think of my layout - I think I<m pretty happy with it. Basically all power on the bottom, plus mono amp. Top will be the Zapco, 4-channel amp and smaller 2-channel amp. Left lots of space for passing and securing wiring. Open to any constructive criticism!!!

I think it looks really good so far. Everything looks like it fits really nice and really tight. The little things to really make an install look sharp! 

I wish I lived in an area where I could show off my equipment. I have to hide everything as much as I can

More progress Sunday - got the second level of the amp rack completed.

 

 

incoming picture dump!

 

 

Here are some of the bottom amp rack testing fitment with gear;

Next the top amp rack - started by cutting the shape out to match more or less the OEM floor shape. Figured that the two side shelves, where the OEM false floor is held, would be a perfect spot to hold the top rack as well.

Next, made a nice cutout in the front center of the second level for multiple reasons: Firstly,  it allows access to the two M10 bolts where the bottom amp rack attaches to the subwoofer enclosure. Second, I will be passing all wiring from bottom to top through that opening. Third, and finally, it makes a really nice grabbing location to slide the top amp rack out of the way/remove.  Since I do not have thousands of dollars worth of Mobile solutions templates (nor would they be justified since I do not do this full time) I got creative and cut a piece at 45 degree on each end, then used two more pieces but up against that to make my cut-out with the router;

Turned out exactly as I envisioned. Rounded over all edges for a nice clean finish (hard to see from photos);

Next was to finish off the box (minus the top) - that includes, finishing and glueing the bottom round piece, adding my two Dayton terminal posts, and installing my two threaded inserts where the amp rack screws into the box;
