Mercedes E350 Coupe speaker upgrade advice

[Patrick1964]

I have a 2013 Mercedes C207 with the non Harmon Kardon system and I'd like to upgrade the sepakers in the front of the cabin. Can anyone advise the sizes or a place to source ? I've looked at a few online retailers and they don't seem to list my car, but I can't believe there's nothing that will fit.

Thanks in advance

Easiest to take the door panels off and measure them. Also, if they're screwed in, take them out and see much much depth you have before hitting the window mech. But some manufacturers rivet them in, which is a pain when you're just checking.

I’m sure Match, Audison and Focal will do specific kits.

If I was in your position I would be spending my money on amplification/sound processing, it is rarely the speakers themselves that are a low point in a system.

Just in case anyone is looking for the answer to this problem, the only UK based supplier who know what they are doing when it comes to specifying speaker upgrades for these cars that I could find is https://www.commandonline.co.uk/Sound-upgrades/
