door speakers
in the rear it is a metric size, however you can fit a 5.25" mid/woofer or coax in the factory location
I am currently doing a system in my 300e similar
in the rear I am installing Diamond Audio 5.25" coaxials with seperate crossovers.
In the front I am installing Diamond Audio 4" midranges in the stock locations, Diamond Audio tweeters molded into the pillars and Diamond audio 6.5" Hex woofers in the factory door locations.
Overall it will be a very stock look..
Single 12" dual voice coil subwoofer in the trunk.
The front system will be biamped (100w x 2 going to the 4" and tweeter) and an additional 100W x 2 going to the 6.5" woofers) the Rear 5.25" coaxials will be driven with an additional 50W x 2 amplifier and the subwoofer is driven by a single 500W monoblock subwoofer amp.
I will post photos once it starts, right now fitting the bumpers and skirts then off to paint..
the rears are 5 1/4". they didn't fit easily so some messing about was needed, but they do the job.
