I will most likely have the same setup when I trade in my Type S for a 370. Here's a shot of my Nine.1 and Nine.2 powering my 13ov2 and edi 6500s in front. I also have FULL deadening and an overall hell of an install (took me a month). Props to a great install! I'm sure it sounds amazing (with that sub and) in an even smaller cabin compared to my RSX.
Also if you notice in my pics, I bolted mine down in the 4 corners b/c I track my car quite often (and they do NOT like that I have a sub, neither does my suspension). How's the stability of the enclosure, did you do anything else to secure it?
