Just finished a bit of (for me) a mammoth build. Was very disappointed with the stock audio, and Canton wasn't available at the time. Have ended up installing the following:

• Match m5.4 DSP (Running Active crossover for the fronts. The rears are still off the HU, and I generally just run it faded to front. I may add another amp and take a line out of the DSP to it to drive the rears at some point).
• Focal Flax PS165FE
• Match PP8E-Q Subwoofer (under trunk floor)
• Musway aluminium speaker rings
• Dodo speaker surround foam / back foam

 

Got the last of it in today, and I can say after a (very rough) DSP tune I'm really quite happy with it. I understand the speakers take a lot more running in, and I need to do a better job of both the input and the output EQ, but it sounds night and day, like something I'm going to enjoy listening to. 

 

Biggest challenge along the way turned out to be how best to power the amp. I wanted to use high power mode so that I can drive 60Wpc from the Match, and 120W to the sub. I ended up finding a salvage fuse box, and removing the wire from the back of one of the maxi fuses to put in an unused maxi slot in my car. The dash crossmember has some really good grounding points, and both of the above are right where the Match ended up (behind the glovebox).

 

The only bit that I'm struggling with now is the input EQ, or ideally flattening the sound dataset on the MIB3. I've tried just about every different adapter and software going, but don't seem to be able to read / write the datasets (even though both OBDEleven and VCTool suggest I should be able to). I've ended up with a DoIP adapter now which is fantastic, and I rather like VCTool. Does anyone have an ODIS / VCDS / VCP setup in SE London / Kent that they'd be willing to help with in return for many crates of beer?

 

Happy to share any further details of the build.

Remaining to fix / do:

• Hopefully flatten the sound profile of the MIB3
• The center speaker is still there, and annoyingly if I disconnect it, SOS throws a fault code / error in dash. Not sure how to silence it, or how the radio is configured to play audio through the SOS module. There seems to be no coding / adaptations for it.
• Still unsure on the input sensitivity on the match. There doesn't seem to be a straightforward way to work this out.

Subwoofer fits perfectly wedged in foam in boot

try without the subwoofer, just connected the DSP and try it.

Sorry not sure why you mean?
