Interesting Stewart, I upgraded my Pioneer stereo & speakers to a Sony Bluetooth stereo & Focal speakers.
The Pioneer stereo I fitted was at the cheapest end of the range and the Sony an improvement but from what you say its worth spending more especially in a Morgan where the stereo has a more difficult job to be heard.
Having only 2 speakers and a cheaper stereo, I think a Sub would probably make a bigger difference to me so I look forward to your photos and findings.
