Finished speaker rings which house the original plug.
Some captive nuts in the print with some M4 bolts hold the speakers securely in place.
Some cheap hardware store insulation on the outer doorcards prevents the plastics from shaking along.
Final layer of STP Biplast 10 MM. Sound absorption and anti rattle. This stuff sticks like crazy!
30A fuse in the engine bay together with 2x 6mm² wire fed thru the hood release cable hole.
Next up is wiring the whole thing together. I bought some plug and play harnesses which in the end was just way to big to make it disappear behind the radio.
So I went the proper way and just hacked in to the original wire loom. Less connectors and overall much better since I soldered it professionally.
The Match M 5DSP lives in the dashboard on the right as you can see. Both crossover filters wrapped in anti rattle cloth and tucked away behind the climate controls. Luckily there is some space in the dashboard
Tweeters where mounted on top of the original covers since they where a lot bigger.
Finally some finetuning the whole system.
This Match M 5DSP is an amazing product which blew my mind on how much functionality there is. Each speaker output has it's own DSP! you you can tune each speaker as you wish. Equalize, delay, phase is independent on all channels
After about 30min of adjusting these are my graphs.
Green are the stock rear speakers, which sound so awful. Did my best making them sound a little better.
Muting the front speakers just reveals how bad the original rears are. These sound like they are playing in a plastic bucket
Also when routing the front speakers input to all 4 speakers outputs reveals how suppressed the rear signal is.
Blue is front, needs some more calibration due to the tweeter reflection on the windscreen.
The sound is so much better now. Deeper bass, crisp high tones, more volume and no more booming resonance from the tin can doors.
I strongly recommend an audio upgrade
