Asking a very small speaker to reproduce bass can be an issue when the design did not call for it.
I think what Mark has described here is the improvement I'm hearing
I'm listening to 80's & 90's pop/rock music primarily
A cleaner crisp sound from the doors and about the same nice kick from the base speakers behind my seats
Same way it sounded in my Coupe with the 220uf / 25v capacitors
