Planet 9

Hi Guys, looking to upgrade my electronics a little while I am car insane..

So here is what I am thinking.

Magden Performance computer - magden-auto.com - with boost sensor and oil pressure.

Kenwood DNX9140 head unit.

The Magden video out would connect to the OBDII port and video to the DNX9140.

Also I would connect my Traqmate video out into the DNX9140 as well...

Anyone see any issues with this setup?

ooo, NICE. I am itching to get a 9140 but can't bite the big price tag...need an amp too cause I have bose.

really on the amp?, I heard that you can bypass that issue buy using the ASK pin on one of the other connectors.. and use the stock sub, and bose premium spreakers.

I will find out tomorrow :-0

HI Guys, yesterdays install went ok, - Lots of work to do.

I have ( had ) the bose system. Here is what we did.

We read all the forums we could about this, then decided the best game plan.

We took out the stock head, took out the stock amp, took out the Cd changer. ( all for sale soon ).

We decided not to use the Kenwood as an amp. So we installed the Alpine PDX-5 - 5 channel amp. We used JL audio cables from the head to the amp. We then used 4 gage fostgate cabling for the amp power as well as a 140 Amp fostgate breaker. The amp is mounted where the stock amp was located.

In the location in the front where they Cd changer was located there is a about a 4 inch hole on the inside, we snaked the power through this hole. Then on the master cylinder side we ran all the signal cables.

We also decided to place the magden computer where the CD changer was located.
We are also relocating the Traqmate system to this location as well. All in all we had to snake 13 wires from the front into the cabin area.

We powered up the system, and listen to a cd, WOW it sounds great! I would have to say it is a 300% improvement over the stock system. Highly worth running all 5 channels to an amp that has all 5, so you get an even sound.

Ipod connection worked great, Navi worked great as well.

Today I will finish hooking up the Magden and the Traqmate, finish tucking in the wires, try it all out, then put it all together.

When finished I should have AV source1 as the magden on the screen, and ca see all the OBD2 data in real time as well as Boost form the ZT-2 connector, and the Traqmate video on the AVsource2.

I think once complete this system should be a little more powerful then the GTr system :-)

Awesome job!
1. Did you have to put anything in line to the speakers to bring it down to 1ohms since the Alpine amp can is only stable down to 2ohms?
2. Is the Alpine running all of the speakers including the Sub?
3. The kenwood has 5.1, how is the center hooked up?
4. Is the wiring for the speakers sourced at the headunit or the Bose amp?

Thanks! I should check out your ride soon, since we in the same area. I am in SJ, what about you?

1. Not needed the Alpine is a Fine amp at 2 ohm..
2. The alpine is running 5 channels. - Not the sub.
3. No, the little center spearker did not sound good at all , ( to small ) so we removed it...
4. This goes form the head unit to the front to the Alpine, them from this location out to the speakers.

I am in San Francsico.


Ok , here is one for ther Gurus out there.

I have the sub on the pasanger side hooked up to the sub out of the amp. ( line feed, it is on a Y splitter cable ) , the sub has power, and it looks like there is a trigger wire ( white/yellow ) Does anyone know where I can get a source for this, so I can get it to see when the Kenwwod is on, and turn on the built in bose amp?

I am in the process of doing a similar equipment install on an 04 Targa. I was under the impression that the Alpine PDX5 has four stereo channels & one monaural channel for the sub. At least that is what my documentation shows. I see that the Kenwood DNX 9140 can drive two fronts two centers & two rears. (Kenwood claims 40 watts per channel but the write up on the similar 8120 at Crutchfield says no way 20 at most) I was intending to have the HU drive the door speakers while the amp would drive the front & rears & sub. The point about one ohm is that the sub is one ohm & would have to be wired in series to increase it above two ohms to satisfy the Alpine (2-4 ohms). All of the other speakers are 2 + ohms so ther is no issue if one uses the PDX5 & stock Bose speakers. I'll be interested in seeing if your trigering solution works. Keeps us apprised.

So I read a little more on this forum (many thanks to all contributors) and I think I understand it now.

All speakers are 2ohms except the door subs and Bose Sub at 1ohms. The rear sub (I have a boxster) can be fed with line level input from the head unit.

A 5 channel amp stable at 2ohms will work perfect. The amp front channels will run the 2ohms door and dash speakers (2 connections in the harness for 4 speakers). The rear amp channels can run the rear speakers. The 5th amp channel can run the two door subs, in seriel to bridge to 1 ohm.

The headunit's line level output can be fed directly into the Bose sub.

I think I got it right...anyone care to correct?

I have this currently on my set up , but it is not yet working.. waiting on a reply on this from an installer here on the board.

I think your fix is here: http://www.planetporsche.net/cayman-...-bass-why.html

Yep that worked! So looks like the wht/ylw wire from the sub to the blu/wwt amp control wire from the head unit. Then connect the purple output wire from the unit to the orangge + wire on the amp. I found that if you connect the prp/blk wire as the - wire, it wil have to much power to it and over power the system ( loudest speaker ) so I grounded the orange out wire from te bose adn this sounds great. I get nice sounding bass that is even with the rest of the speakers.

Here is the update from last night. I got most of it installed, tested and working.

Just have to do the clean up and it is done..

Hmm, I wonder what the leads you described as colors are actually for.

__________________

I have a DNX8120 installed and I am looking into installing a Magden performance computer as well. I personally would like to enjoy a little music during my racing, so I would like to connect the Magden video output through a video selector and into the DNX8120 rearview video input. I am hoping to do the same with a radar detector but have yet to find one that has a video output. I would also like to build a circuit to integrate the reverse gear input with alert discretes from the radar detector and Magden PC but these discrete don't exist yet. Anyway, regarding the DNX9140, I thought maybe I should have waited, but now that it is out, I see that the major improvement is voice command while at the same time not only have they not yet resolved the issue of supplying a KAB splitter, the DNX9410 will not support the GXM30 which currently provides traffic/weather/stock data along with XMRadio almost anywhere in the USA such as in the mountains. Note that the XMRadio (unlike SIRIUS) signals come from satellites over the equator which is Southward to us, thus are occasionally blocked. While the DNX9140 does support the MSN Traffic receiver which provides more data services the coverage is limited to major cities. This means you also must choose between HD Radio and Sat receiver through the KAB connector. Of course Kenwood is still promising a KAB splitter but don't see any sign of it yet. Also, don't know if teh GXM30 issue is caused by the Microsoft or perhaps just a software issue of getting the Navi to support either one. Note that only one USB cable can be attached to the Kenwood Navi so you have to choose. If both could be supported I would probably have both XM and MSN data services.

no pics of the headunit installed yet? common, show it off.

HI I will get some more pics up :-) it is taking a little time as I am working out a few other issues. * screen logo, cayman car icon on navi, different voice, boost gauge power, etc.. then will post pics once complete... Getting there., just my in laws have shown up.

So far I am loving it though, Nice sound, to many features to learn in a week.

The magden is working out fine so far. One thing I did notice though, if you have it on when the car starts, then you may get a check engine light, saying that the car cannot communicate with the DME. The way I figured out how to get around this, is I took the OBD2 port out of the holding bracket and I attached the cable and placed it above the opening so my knee does not hit it, then I added a switch to the power of the magden and mounted it in that OBD location. So I can turn it off and on when I want to see it, and it is not always on, or always on while stereo is on.

Ok so I have now installed the Kenwood DNX 9140 into my 04' Targa. A few points for those who might want to use the existing Bose speakers which I did. I have the M680 pkg (cdr 23 & 6 channel MOST amp) which gives me dash, doors, & rears as well as a sub by the passenger footwell. I am using an Alpine PDX 5 amp. The fronts- tweeter/midrange are 2 + ohms & the doors -midrange are also 2 + ohms. The rears are 4+ ohms tweeter/midrange & the sub is one ohm & is not separately powered. This drove me crazy since the documentation is all over the ballpark & of course this is a 996 & not a Boxster which I assumed would have much of the same wiring but--. Bottom line I connected the doors & dash in series which gave me 4 + ohms as measured at the harness. To do that I found that "Pep Boys Auto Stores" (national auto parts store) carries male connectors for the Bose premium sound system installed in many GM cars. I then connected these to the Alpine speaker wires & used heated shrink wrap insulation which was perfect to allow the connectors to be pluged into the existing female factory MOST harness. I needed only two jumpers to connect the negative to positive wires of the Left & right dash/door speakers to enable the serial connection . Then I connected the other two wires positive & negative back to the amp for each side. That required only two channels & the rears took the other two channels of the Alpine. After a great deal of angst & a recommendation from Greg who has posted here & is an engineer as well as a former installer, I simply turned the gain way down on the Alpine for the unpowered sub channel & the system sounds just terrific. I can use all of the head unit controls & I have true 5.1. I also used an audiovox rear view camera which worked out beautifully. Finally there have been many posts on the AVIC3 & the bypass hack as well as the speed sensing wire. The Kenwood has no wire for speed & the bypass is super easy. It just require that the ground wire be connected to the parking sensor wire. I do not recommend placing the GPS antenna under the alarm sensor at the front of the windshield. IT is just way to much effort & you are likly to break something as I did. In retrospect I would place it under the plastic cover in front of the windshield by the trunk. It only needs not to be blocked by any metal going to the sky. I did this with the Sirius antenna & it works great. That will save hours of hassel. If you have a 6 channel system it would be even easier to get a new 6 +1 amp which eliminates wiring speakers in series assuming the amp is stable down to two ohms like the Alpine PDX 5. I also considered other alternatives such as wiring the doors & sub together which I may still do since the plug in harness has worked out so well. There are no wire splices with this setup. But at his point I am really happy with the sound. I also placed the voice command button in the ashtray which keeps it out of the way unless used & is also a very handy place for it. The microphone will eventually go where the factory mic is located behind the plug next to the instuments but for now it is zipp tied to the steering adjustment handle below the steering wheel. People tell me the bluetooth sound like a high quality speaker phone on their end with no odd noises.
Question: Is there a separate wire in the factory cdr 23 plugs for the antenna control wire from the head unit to be attached? Since there is no powered antenna I am wondering if the antenna might in fact be amplified thus requiring a connection to the head unit in addition to the plug in antenna? Thanks Cris

Hi CMG... Glad some one else went with this set up as well! I really like it , it even sounds better then my qaudzillion speaker Cayenne premium package. The 5.1 surround is Cool in a car!

The only differences we have is that I did strip all the wires out, added JL audio wires from the head unit to the amp, and on the amp I did put both door subs attached to the sub out and I have the center sub hooked into the head unit.

I did put my GPS antenna on the dash in the corner on the passenger side ( PAIN! ) Also I drilled a hole in the glove box to run the Ipod and USB cable. ( so it looks clean. and the glove box closes correctly. ) The push to talk button I put next to the wing up and down button, and I mounted the mic next to the MPG reset button, so it is directly pointing at my face when talking. ( I too damaged one part in this install ;-(

Yes there is a wire for the powered antenna as well. I am not sure what wire it would be on your car, as our wiring is different, you would have to look at a wiring diagram. In the cayman it is a little white/blue wire.
