Making the 911 that Porsche were too sensible to consider

Stereo - there were two options for this era of 996, one that had no name (basic? default?) and the "hifi" option that mine had. The standard version had mids and tweeters in the dash and next to the rear seats, the hifi option added an amp and a woofer in each door. There was a CD player in the luggage compartment, nestled against the bulkhead behind which the battery resided.

I listen to the radio a lot, and there was something which interfered with the radio signal. This wasn't on.

I had the antenna amplifier replaced, then the head unit, then I replace the amplifier and all the speakers, then I replace the head unit again - none of this fixed the interference problem, but I did have an extremely good stereo by this point. Oh, and I'd added a subwoofer.

I've not yet got the car back, but the place that has it at the moment say that they've resolved the interference problem by grounding the stereo to a unique ground point on the chassis, rather than it (as stock) sharing an earth point with the rest of the dash. We shall see, but hopefully it'll now be the stereo I've always wanted it to be.

I've got Morel separates in the dash, silk-coned mids and tweeters, a Focal powered sub under the dash on the passenger side, two Hertz woofers in the doors and two Hertz combination mid/tweeter units in the back. However, I now have only a four channel Morel amp, so the rears are unpowered (my old, six channel D-class amp was considered to be a possible source of interference).

If the new setup is what I want it to be I'll likely delete the rear speakers, change the woofers to Morel so everything matches, and call it good.

One other reason to delete the rear speakers is that I'm planning on removing the rear seats completely and turning that area into a luggage compartment.
