Hi John,
The factory amp is really nothing special. The most benefit you'll get out of it having the cross overs all setup for you to the various speakers. I would just bypass the fader and the amp and just run directly to the existing speakers. They are decent on the premium sound system which I believe all the 325is models came with. I'd also pick up a cross over to split the signal to the front tweets and midrange down in the kickpanel.

>From the factory wiring, I'd just use constant power to the Blau's memory
power line, ign power to the Blau's main power line, white wire to power antenna, and ground. Antenna also of course, you can get an adapter from the odd factory micro connector to the normal full size one the Blau will expect.

The Amp internal to the Blau is probably 35w/channel, and sounds better then the 12 year old 25w-35w/channel factory amp.
