Anyway, the reason for the soundgate box is that the M3 came with a separate amplifier that doesn't expect the higher output level of the Toronto.
The previous owner of my car had already taken out the factory amp when they put in the "ugly gray Pioneer with green illumination" so I didn't need the box. I sent it back for a refund.
Obviously, if you have the stock stereo, then you have the factory amp and should either use the box or find and remove the amp. If you are using the stock speakers, it would probably be easiest to use the box. If, however, you are going to wire up some new speakers too, you might want to take out the factory amp. That would be a more ideal "clean" way of doing it.
BTW, you are lucky if the factory wiring harness is intact since the crutchfield adapter will plug right in. On mine, the PO also hacked that out so I had to wire everything up myself.
Hope this helps,

I recently purchased a Blaupunkt Toronto CD receiver for my M3. After a talk with a Crutchfield rep, I ended up buying two adapters to connect the BMW OEM connectors to the receiver (requires minimal soldering) and a receiver interface "to connect the new receiver to the car's wiring system at the proper levels." (his words) I'm not exactly sure what he meant by this so I would like to know if anyone else has replaced their factory stereo with an aftermarket unit and has used a device like this. The unit is about 2"l x 2"w x 1/2"h and is made by Soundgate. The atapter and interface were relatively inexpensive and I can return the receiver interface if need be.
I'd appreciate advice anyone can offer.
Thanks and take care.
