I have 2002 320i with the stock audio system (not upgraded)
Like many others, I feel the stereo is lacking.
I would like to install an amp & sub woofer.
Does the HU have a sub output or how do I connect to the Subwoofer Amp?
Thanks

There is a very comprehensive writeup about tapping into the stock harness to add amps over on e46fanatics.com's Mobile Audio forum. It should answer all your questions. I think it's pin 8/19 and 29/36, but I could be wrong. Oh yeah, there are pics and explanations of what that means and where to locate them, also. Pretty simple, as long as you take your time.

I've added a sub and amp and it's a pretty easy DIY. In the US, the OEM amplifiers for both the non-H/K and H/K system are in the left side of the trunk. I've heard that in other countries the amplifier is built into the head unit. If your amp is in the trunk, it will be a much simpler job.

You should take apart the lining (should take around 10 min) and see if you have the amp there.

Thanks for the info guys.
I will look into it this weekend and post the results.
