Most CD-decks can be made to fit our cars, it is more of a question of what you are looking for.

Unfortunately, a lot of products out there have really gaudy lights and obnoxious graphics on the face plates. You may want to have a look at some Blaupunkt units if you a looking for something a little more subdued and classic. The Nakamichi units aren't too bad looking either, a bit pricey though.

I used to be a fan of Blaupunkt, but after replacing some of their top of the line head units w/ similarly priced clarion and alpine units I was astounded at the improvement in sound quality.

A big part of the equation is how much do you want to put into this set up?

Just wire the blue wire (on most head units) to the wire leading to your antenna switch.. IF my memory is working I think it's a blue wire (perhaps w/ a tracer..) on the MB as well.

Very easy.

thanks.

I notice that when I turn my radio on (I have the stock Becker Grand Prix deck), the antenna goes up about 1/4 the way up and stops. I always need to extend it fully using the antenna switch on the console. Is there a way to control how much of the antenna will be deployed by default upon powering up the stereo? I can't just keep the antenna Max switch on because I hear the antenna "grind" once it reaches full-extension (and the electric motor keeps running even after the antenna is fully extended).

Yeah, the back speakers can be a bit of a pain as they have a special mounting rim and there is relatively little space underneath the shelf.

Basically, the speakers are 6.5" and with a little bit of work, a standard set of speakers can be swapped for the original ones. Alpine, Pioneer, MB Quart, they all have 6.5" replacement units from $60 to more than $300 per pair. It really depends on how much you are willing to pay.

Remember to remove the rear seat before you lift the speaker covers.[8)]

hey

i just put a subwoofer in the trunk of my 300sd, (3- infinity 1203s) and i was wondering if anyone had recommendations on running air ports or something like that in the deck? Maybe throu those storage compartments? Also any reccomendations on trunk padding to dampen the sound outside the car?

Dynamat is the way to go!! I have removed the rear parcel shelves to provide better airflow, but I have not got around to the custom install yet. I won't be using my Infinity Perfect's either, so I need to work on getting the JL Audio W6 V2s first!!

The Dynamat trunk kit!! You can get it for 199usd installed. Includes 2 pieces of Dynamat extreme and 3 pieces of regular Dynamat, if I recall correctly.

Another thought, I may install a switch to turn off the subs. I was thinking of just using that Rear-Window Lock switch, you know? I mean i never use it to lock the rear windows. Thoughts ?

i just replace my old beaten up blaupunkt with an Alpine CDA 9827: cd & mp3 player, am/fm, yadda yadda.
it sounds and looks great, nice simple classy face and fits the car wonderfully. and though i thought it was a little more than superfluous at first, the remote is great and rather handy.

Good luck with your Alpine headunit!! Not to scare you or anything, but I am on my third in 4 years!! CDA 9831 was my most recent acquistion, but I got my CDA 9813 back in now. The 9831 didn't quite do it for me, so I sold it. I do miss the Alpine Amplifier controls though, they were great!!

FryFar,

In order to remove the seat backs you first have to remove the bottom sear. It is fairly simple, there are two levers below front of the seat, push those outward and lift the seat bottoms out. Then take the seat backs and slide them upwards and lift those out.

Now you have access to the speaker covers. You remove those by sliding them forward. The speaker covers are held in place by hooks in the back and pin in the front. You'll probably find that the foam underneath the speaker grills have disintegrated (or at least turned very dry and brittle) so you may want to remove/replace that as well.

Once the speaker covers are off, things should be fairly obvious as everything is accessed from the top (you don't have any access from underneath...).
