how to adjust tweeter from DSP? (Match5DSP)

So I've got a s205 (station wagon version of the w205) and been down a similar road.

Are you sure you're not clipping the input of the amp? Also where do you feel it's distoring, the focals have a big boost at 10db above 10KHz

There is an old saying of **** in **** out, if you're clipping the input (remember the input of a modern DSP based amp is an analogue to digital converter) then you're never going to un-clip the waveform in software. Looks like the Match has no gain pots, not sure if you can set them in software
 
Getting the tweeters active in a w205 series Merc is a pretty invasive job for a n00b. It's easier on the base cars as the amp isn't in the boot, but still a lot of work with the doors etc and how the connector works.

This will be something simple, just needs taking to a pro for half a day. Ultimately it's going to need a proper DSP tune anyway.
 
No you'll actually get the same wattage, as you'll drop the impedance to 2 ohms on the amp load. However you'll sacrifice time alignment and ability to do differential rear fill.

Personally I'd add a cheap amp on the line out and go with:
  • 1&2 tweeters
  • 3&4 mids
  • 5 running two bulkhead subs bridged mono
  • Line out into cheap 2 channel running rears.
