Got 2 nsx 12's off an audio element 5k in a box with removable port tuned to 29 hz, front stage is nsx6 speakers off a random 4 channel, pioneer touch head unit, 0 g wiring with the big 3 update done and whole boot sound deadened will post photos later ;p
dbdrive system with memphis amp and custom boot package. They provide a clean, studio quality sound and I am very happy with the whole system. A few screws and you can take out the subs and access the spare wheel.
By far the best sounding system I've had, got it 2 weeks after the car (approx. 6-7 months ago) and I still smile from ear to ear when I get in the car. Btw I am not a brand ambassador - just a very satisfied customer.
