You can find Morel car speakers here:

My system has been built from the Elate series replacing the OEM speakers which were just the EU basic - sounding flat. Morel is a renowned Israeli maker of audiophile speakers for custom built home speakers and car audio.

The power comes from this Swedish baby:

It is DLS Ultimate A3 twin mono amp for the front speakers and I have a DLS Performance CA23 for the rear. No trunk subwoofer...
The system is built as stealth, nothing can be seen but heard...
