I'm not quite sure what people are expecting from the sound system in an open topped car at speed. I've had quality sytems in my Mercedes and Porsche Cabriolets and found that wind and tyre roar will always overpower any sound system.
I find the standard system in the Morgan Plus Four whilst a tad basic lacking depth of bass, is more than capable of being heard at motorway speeds.It may not be brillant, but it can be heard and more than enough to be enjoyed.
I find the roar of other vehicle tyres especially EV's is very invasive these days...............but you pays your money and not always get that much more advancement in the quality of the sound reproduced when in an open top car roof down at speed.
