Project Dynavin - audio installation















The Best of Mercedes & AMG
If you are going to do the floor, use the matting with the foam underlay rather than just the regular style, it isolates road noise far better and it great to cut channels into for wire routing



We should start a new thread in the Lifestyle forum https://mbworld.org/forums/audio-video-129/
I have to get going now to leave for a few day trip, but will be happy to post in it and chat about home audio when I get back.



If thats the case and you want to skip buying the amp, then you can use the Dynavin HU to power the speakers as it has 4x45w build in amp. Sure the sound will suffer in terms of fidelity but its your choice. So in theory you should be able to remove the existing HU, basically plug and play the Dynavin in to the same plugs and it should work. One other question is what speakers you have. As you mentioned it does not say Bose on the subwoofer located on the rear shelf and as you only have option 254 RADIO MB AUDIO 30 - USA per your VIN, you do not have Bose. Hopefully these will be normal 4ohm speakers and Dynavin HU will then power them fine. I think only Bose uses the 2ohm speakers as their amp is basically not build to be able to power anything bigger but I do not want to get in to Bose debate here

So confirm yo do not have an amp and the Audio 30 HU is powering the speakers and confirm these are 4ohm. Then you should be plug and play and no need to run wires, replace speakers and add amps. Now if you are after good sound then you will want to replace the speakers anyway and add a good amp. That will also require running power / audio signal cables to the amp and some rewiring for the tweeters and crossovers etc.



Originally I was looking at the Focal Access 165 A1 and CA1 speakers and Alpine PDX-5 amplifier.
After a bunch of research I settled on Polk Audio DB6501 and DB651 speakers and the Kenwood Excelon XR-5S Class-D amp. The speakers have very good review everywhere I looked and cost quite a bit less then the Focal's. The Kenwood is a 5 channel amp, is the same size and about same specs as the Alpine PDX-5, had good reviews and was less then the Alpine. I also got a bunch of RCA cables, power cable/fuse, etc. and a roll of Dynamat for now just for the doors. I'm still missing the subwoofer but have not decided on one and its an easy add on later.
It was $890 for Focal's + Alpine
verses $515 for Polk's + Kenwood
As I'm replacing Bose, its a car and not sure how long I will own it, I decided to go with the lower cost. After all even the lower cost setup should blow the Bose away





The Class-D amps used to have issues with the lower frequencies but that was maybe 8 years ago when I looked at them for a speaker setup. I think the best ones were from Meridian at that time and my Proton Class-A solid state mono blocks were far superior. I'm 100% in Class-A Tube amps for my headphone rigs.
For the car this should be great and more then sufficient. I'm after sound quality and not quantity.

If I want HiFi, I got that at home
Congratz on your purchase of Dynavin HU.
How is the peformance so far?
I had installed a unit to my 2006 W211 but facing poor radio reception..and same problem also happens on my other W203
Do you face the same problem...?
There is one thing which I dont really understand that the stock unit has two fakra connection on unit where 1 is black (RF radio antenna) and yellow (ZF). As shown as per below 1st picture..
but Dynavin unit has only one input for FM antenna as shown in 2nd picture.. this really puzzle me as i only connected the black cable to the adapter and to the dvn-mbe antenna connection, and left the yellow one (zf) disconnected.
I am wondering, leaving the yellow one (zf) disconnected would it be the possible cause of the poor reception..
How bout you? Did you left the yellow one (zf) disconnected as well?
Would like to hear your experience...thanks

Also I still have not installed it, short on free time, but starting to run the wires so if all goes well I'm hoping to have the install done by next week.
UPDATE: sorry misunderstood, the first pic is your stock HU

As I am aware, I am not the only one facing this problem.
Quite a lot (not 100%) of Dynavin purchasers for Benz range from C class , E to ML class having the same problem

Good luck and all the best mate .
