04/16/2001 - Harman TrafficPro - By: Carter Lee
At Homecoming 2000 last Labor Day Weekend, there was an additional commotion beyond the regular vendor area frenzy. Harman Industries of Harman/Kardon kept a Pistachio Green roadster in their tent to show off a special head unit called the TrafficPro. This gadget is befitting of our "Bond-cars" in that aside from being a DIN-sized in-dash CD Player, it integrates a GPS Navigation system.

I've wanted to upgrade my Z3 sound system for a while. I found that the stock system simply wasn't good enough to support a convertible.

10/25/1998 - HK Amp Swap - By: Fred Reinemeyer
The BMW Stereo trickle down theory, those roadster owners with HK amps sitting on the shelf can find new homes for those amps and put a little money in your pocket.

Feeling left out of the upgrade pandemonium with your '96 stock stereo? Not too keen on dropping tall cash for automotive surgery? There might be hope yet...

Using the factory head unit and CD changer, I upgraded the amp and speakers and was very satisfied with the results

01/01/1997 - 10" Subwoofer in the trunk - By: Alan Riley
Amp, Sub and Crossovers all mounted in the trunk, this is one serious stereo setup.

03/28/2001 - 4 inch Rear Speakers - By: Perry Esposito
In the continuing quest for better sound in a Z3, I decided to replace the stock rear 3" speakers in my 99 2.3 with 4" speakers

06/12/2000 - Sound System Upgrade - By: Thomas Young
Anyone who has visited the Z3 message board has come across many discussions and complaints about the stereo system in the Z3. One would think that for the money (and the fact that its a convertible) it would have a decent sound system. My '98 roadster came equipped with the Harmon Kardon upgrade which offers a few more speakers and the infamous sub-woofer system.

09/29/1999 - The Harman Kardon Affair - By: Sam Quiros
I will not be competing in any auto shows, but it sounds a heck of a lot better than the stock system, virtually no modifications to the car at all, and 99% of my trunk space is still available.

07/31/1998 - Robert's Stereo Upgrade - By: Robert Leidy
This is a stereo upgrade to learn from. After nearly a month of trial and error this is one upgrade that sounds really good, but was not worth the effort.

New Amp and speakers - DC completes Part 1 on his stereo upgrade

06/27/1998 - HK Sub Dissected - By: Robert Leidy
Just had to see how this HK sub worked, so I took it apart.

04/27/1998 - Beating the Buzz - By: Robert Leidy
If the subwoofer in your HK stereo is buzzing, rattling or sounds like it is blown. Try this very simple fix, because the porting tube might have come loose.
