Hi Wing

Tbh I am happy with the 380W it's just because I'm running a road angel that I noticed I had the wiring etc and it wound have been nice to retrofit one MY14 Kahn Converted Dynamic - Fuji White Ebony/Pimento Interior
MY15 Xenon Headlight Conversion

MY17 RRS SVR - Estoril Blue Cirrus/Ebony 🪣💺’s

Not sure I totally agree with Wing, I prefer the Meridian setting, however, that said it does need to be turned up, at lower volumes it can sound a little tinny.
It's a strange sound at first as it really does separate the voices and instruments, it's quite strange flicking through the settings and listening to how differently tracks can sound.
Of course, audio is a very personal thing and everyone is unique in that respect, so there is much to be gained by experimenting with the settings.

I hope you resolve the issue and get the centre driver working
