Well the rear speakers to me are HUGE. Since I have a Boxster and the rear speaker help to fill it out for my ears. I know there has to be some way to get this to work with the rears on as well.
Yeah the selling point for me is the display as well. I don't like childish looking gear. My buddy has a Avic-d3(I think) with a nice glossy trim frame with PORSCHE(in their font) and the display is adjustable(set to Porsche amber) and it looks OEM. If it was some green or blue it'd look wack.
What are these 'wire nuts' your speak of? Did you have to buy any other parts to install or was everything there from Crutchfield?

Also, today I figured out how to get my rear speakers back, thanks to your tip on splitting the outputs via the Y RCA adapters. The JVC unit only had front RCA outs. Since you provided the wiring diagram showing the front and rears going to the same RCA out, I was able to split the two into four and now have all speakers working! And it has so much bass, I actually have to EQ the bass lower. Sweet!

The fader doesn't really work, but I think that's the only way to do it with this particular HU without chopping up the factory wiring. So I keep it centered, I hear my rear speakers fine, and it works so far!

So was the wiring harness that you have to cut and wire nut together pretty straight forward like matching up colors? Did you have to set up any new mounting brackets? How hard was it? Any special tools required.
Let me make sure I get this straight before I start ordering stuff. You split the front left/right with the rear left/right via 'y - cables' and all 6 speakers(dash tweeter and midrange and rears) still work? Also you used the sub out on the receiver to power the door left/right 5.25" speakers?

1) Remove old radio, unplug two harnesses and the antenna
2) Install Crutchfield provided antenna adapter into new HU antenna jack
3) Install metal radio sleeve by coercing it into the radio cutout
4) Wire radio harness to the Crutchfield harness using provided instructions (do this on a nicely lit table)
5) ** reverse the yellow and red power wires!! For whatever reason, Porsche is different than Audi in this case, but the wiring diagram doesn't say so.
6)**wire the blue wires together (amp turn on, antenna) into the HU harness blue wire. Instructions from Crutchfield don't mention this either.
7) Buy 2 of the small Y RCA splitters listed in a link on my earlier post
7) Plug in the two splitters into the top two RCA out jacks on the HU
8) Plug the 4 harness RCA cables into the splitters, matching right and left
9)Plug the antenna cable into the HU from the top down, so the L part of the plug points UP towards you, over the RCA plugs, or the antenna cable will pop off during the final radio slide-in!
10) Carefully hold the radio close to the install area, while stuffing all the wiring back into the cavity so there is room for the radio to slide in without getting stuck on the cables, etc.
11) Install the faceplate, and try it out!
I think that's everything. There are about 5 or 6 wire to wire connections, and the RCA plugs. If you wire it the way I listed here, you have no subwoofer controls, but the overall sound is much better, and I even cut the bass to lower the boomyness. If you decide to wire the front speakers and door speakers, without the splitters, you get the door speakers as sub woofers and can control the frequency and volume seperately. But it doesn't sound as good, and you lose the rear speakers.

I just stumbled onto this thread and its very useful; thank you. I am installing the newer version of the JVC unit that Andy put in (KD-AHD79), and it has two pairs of outputs in addition to the sub-out, so at least I don't need a splitter. I selected it for the same reason that Andy did; the abilityt o match the disply color.
With your instructions this sounds like an easy install (yikes, I just cursed myself!). Thanks again.

Ha! Glad you found the thread! Except for the asinine way the JVC requires you to change the radio presets (push a menu button, scroll with the volume wheel, then push the wheel to choose the station), all is still good. As a tip, I found the "hip-hop" EQ setting works best while driving - you need all the extra bass you can get to compete with the flat 6!

Funny how things change... since this thread, I've completely changed my system. I've got a new head unit, new amp and new speakers all the way around.

I found this thread a month ago when I changed out my factory head unit for a JVC Arsenal unit, and the wiring instructions that Andy posted were invaluable. Meant to post a "thank you" back then, but, well, I didn't. So better late than never: Andy, thanks for your work!
