Viestin otsikko:  Xantia Mk2 - Audio Progect

Hello again :D
That is my estate audio project which was not suppose to happen. Why? Well, first thoughts was just to replace the speakers and stereo with something better and to enjoy.
The joy itself was ok but if you own Mk2 estate probably you can hear the roof over rear seats to make noises in old used bean can stye. :(
Why is that will show you few rows below.

Stage one was the bad - ripping all apart:

As you can see from the last image, the ceiling cover(which by the way is fabric glued over some fiber plastic) is connected via some thick silicone glue to the roof panel. That was bad for taking down. I need to use sharp knife to cut little by little starting from front and back sides. Open little, cut, then pulling carefully down with one hand and cut with other. Simple said - shit work.
And other angle:

Here ^ , pay attention about that same kind of glue applied over the horizontal under roof bars. That suppose to keep the metal together. And as result it lost the connection and the hole roof is wobbling. And when it rain you can hear the drops inside same as you do not have roof.

Next task - doors:

All that done, come the main part: Bitum and isolation

And some small troubles on the way.. :D

So, now when is raining is kind of quiet inside :lol: And because that player has time alignment function you can set the audio stage quite nicely inside. Hope, you like it :D

Very nice!
I did something similar for the doors on my Xantia, but never got around taking the roof apart and insulating it. Apart for the rain noise, can you feel any difference in wind or tyre noise levels when on the road? I couldn't hear much of a difference after doing the doors (apart for better bass!) and was wondering if doing the roof actually lowers the interior noise?
Also clever idea on mounting the amp on the seat frame - I've often thought about mounting it under the seat but never on the seat itself!

All in all, very tidy work! It's so much more relaxing to drive when you have proper audio in your car. :)

Excellent! Huge job, but I'm sure (I know) it was worth it. Thumbs up! 8-)

Great project. Do you have separate amp channels driving tweeters so you can adjust time correction for them separately? Any problems in stereo image (soundstage) in that critical element transition frequency 2000-4000 hz?

@Bumper - road noise is still there. Low but still. And believe or not is coming from the windows and some part from the rubber door-body cage isolation. Was with some idea to remove the seats and carpet adding bitum on the inside area of fenders and under pedals but skip that. Even now, with low volume on the music you can`t hear so much of the engine or road. True it get little better but that is not Rols Roys and even that in my opinion went little too far for that kind of car. :lol: But looking that you`re in Turku if come to Ikea or motonet some time I can offer you to live test it how it is ;)

@ds-jekkeri - In short answer - nop. That one under the seat is 4x60W and that is. The other is 240 mono for the sub. The player itself has 3 x high RCA outputs Front LR , Rear LR and sub LR. The adjustment is made by using the player Low/High pass filters with slope in -12dB on 70Hz. Speakers are on the standard OEM wires in the car only I separate little the rear tweeter from the midbas using additional cable. Speakers come with L-C type filter. That will be more adjustable with some proper sound processor but they cost a lot and in that car that is pointless. From other hand that Kenwood for it money is kind of full of extras. And the only option as DTA is time delay for each channel and bass + speaker and car type selection.
I have some small trouble in some frequency range only by the left front tweeter but suspect one spring in the unit. Soon will get more time to investigate. Overall tight sound and with EMMA Audio test sounds it perform not bad in my opinion. And straight answer to your question - I don`t think has any issues in that freq. range.
