Lucid is out of a few rear speakers so I might be ordering this one.The tsunami version. I think its 4 inch speakers or so but who has these and how are they along with a 50x4 headunit? Any improvement is good just want some rear sound

 

i have the panels with some 5.25" polks, and it is an improvement. the seatback pretty much cuts out the highs, but there is a good amount of low/mid reinforcement.
