I am ready to install an aftermarket cd radio on my 350SD.

A local shop wants 200 dollars to do the installation, on the claim that the wiring will have to be "custom".

I thought I would do it myself and use that money to upgrade the speakers, the amp, and get a nice headunit.

Where can I get the detailed wiring diagrams for hte audio system for this vehicle?

What size are the front and rear speakers? Will it take 6"x9" speakers?

What does the DIN plug connect? The in-car amplifier? SPeakers? or both?

And is it possible to get connectors/harness to hook up to the existing radio wiring so that I don't have to cut the original MB connectors out ? Any aftermarket sources for this?

All tips or links to earlier discussions will be appreciated?

Thanks.
