For X-mas I got my wife a new CX-9 as a replacement for her Maxima SE. It was just time for some more room and the CX-9 has been awesome so far.

The only down side is that I found out that there is no aftermarket dash kit for the radio! I didn't want to use the factory radio and wanted to upgrade her stereo system. So I started reading mp3car.com's fabrication section. A lot of people there create their own dash kits and it's a great place to learn about abs plastic fabrication. So I took the chance and I took out the original radio, cut up the face plate and created my own custom double din dash kit. It's not 100% finished at this point, but I think it's halway decent for a 3-4 days.

Original Radio

This was after I removed the buttons and cut the face out.

This was a test fit with the bezel that came with the DNX8120

I used an ABS Cement / Plastic Weld that bonds the plastic together - basically melting the plastic and forming once piece.

I then used a Dynatron Flexible Bumper kit. It's a two part abs epoxy that, when dry, has the same strength and flex as the cars plastic. The epoxy dries in 15 minutes and is ready for sanding. The first time I let it cure for a full day to make sure that the holes it plugged were solid. The I had to apply the epoxy a couple of times to fix low spots. It took quite a bit of hand sanding and just touch and feel. The process took about 2 days to get it just right.

This was the first sanding. I used a 220 grit and just took my time not to over and and to remove any high spots.

This was after the first spray of primer. For this I used a 400grit, then a 600 grit wetsand.

This was the first time I painted it. I ended up using a textured paint on the primer that is a flat black. This needs to be redone to use a dark gray color that matches the dash, but I could not find any in my area. I'm going to order something from SEM that is an OEM color match and try to do it next weekend.

This is just a closeup of the texture. It matches the dash paint, which has a similar texture.

This is a picture of it in the dash when I first installed it. That image is one that I custom created for her car. I also made a background for it when it's in use. It's really cool that Kenwood allows you to customize it.
Radio in the dash

I installed two Eclipse amps to power the system in a tray that is hidden in the trunk area.

These are all 3 monitors in the system. They are Alipine 7" LCDs that I placed in the headrest and I put a DVD player under the rear passenger seat. The Alpine unit has a processor unit that allows you to connect up to 3 sources. The monitors themselves have IR Wireless headphone output and the set came with (2) Alpine wireless headphones. AWESOME unit and I highly recommend it. I basically have the Kenwood DNX8120 feeding the first AV port and the second av port is supplied by the DVD player under the seat. The monitors can then choose which one of the 3 (or two in my case) inputs they want to watch and the headphones have switches where they select the channel to listen to. It's great because our 3 year old can watch toy story and our 11 year old can watch star wars or something older :)

The sub enclosure is temporary until I can finsh a fiberglass one that is molded into the interior.

The system is

JL Audio 3.5" in the dash
Diamond Audio 6.5" in all 4 doors w/ 1" tweeter
Kicker CompVR 10" Sub DVR
Eclipse EA4100 (75 watts per channel)
Eclipse XA1000 480 watts RMS x1 at 2ohm

It was a bit scary. A replacement Radio is almost $500 from Mazda and I basically had one shot at not screwing it up. lol

My wife was great in letting me try it, but I'm sure she was scared :D

Uh.. topic should be in The Garage, shouldn't it?

Not my taste, really. The color is off from the dash and I would have it matching.

Not if I put a link to Stormtrooper armor fabrication in the thread!

See what I did there, kid?

"Ultimately this needs to be redone to use a dark gray color that matches the dash. "

I know that, but no where around her had a match color. I need to get some SEM paint that is actual OEM color matched paint. I did this over a weekend and had to put it back together for the wife to drive. I will either order or find a paint/body shop in Nashville that has the paint I need and pull it out one weekend to touch up.

It does look a little crooked in the dash; but overall, it looks great.

It is a little bit :D I need to dremel out the holes a little bit to match it up. The face plate from the original radio had some odd screw locations and it didn't line up perfect. I just didn't have the time to finish it, but next weekend I'm going to work on making it perfect. It's my first time doing something like this, so it's a learning experience.


Ultimately, this is to hold me over until Metra or Scosche creates a dash kit. They keep saying they are working on one, but both have been saying that for a year. So I'd rather just have something now and just wait for a real one to come out.

Eh, I dunno, it's just a normal Double Din head unit. The reason why it's great is it has Garmin built-in Nav, Bluetooth, rear view camera, XM/FM Traffic and weather report, Ipod video and audio connection, DVD, (2) USB ports to plug in hard drives/flash drives. It will also play DIVX and other movie formats. It will do dual zone, meaning I can send the movies to the TV in the back and control them, but keep the ipod or radio playing at the same time. Overall it's a very impressive unit.

Looks a lot better than what I could do.

<---Eyes roll of Velcro I just put on my center console to keep netbook in place when used as a GPS, and hangs head in shame.

(I used the same roll of Velcro and netbook to put said netbook on the back of my 22" monitor too when not used as a GPS :laugh: )

Just a thought, a layer of grey sandable might match your dash more.

EDIT: Grey sandable primer.

Appearance-wise, the plastic you did looks great, but something about the radio just looks off.

Yeah, it's not lined up right. The holes need to be drilled out a little so it can sit right. It's a work in progress :)

It's crooked, but that's a better first pass than I'd have the patience to do, so very nice job.

Once you get it straight and some matching paint, it's going to look really good. You might want to bond and mold in that trim ring for the head unit, so that it really looks like it's supposed to be part of the dash. IMO, the aftermarket trim ring is the worst part of doing a head unit. You're 75% of the way there, gotta give you a lot of credit for the work.

Oh man, I had some Eclipse amps in my old Galant. Man those amps were killer. I totally miss selling them when I got my Civic. I've never seen anyone else use them. :)

I had replaced them with Memphis amps in my Civic. Too bad they broke into my Civic and stole them...lol. After that, I said never again will I put sound into my car...but your post makes me want to go blow a few thousand into my Jetta. Damn you!
