Your setup is sounding really good so far. iPhones do suck when it comes to bass though.
I know someone that had that imprint BS and the module itself had a few encounters with the parking lot outside his condo. LOL
He has the double din nav unit and after the imprint module had its accident
he discovered a switch on the back of the unit that needed to be moved if you're using the imprint. There was no mention of the switch in the manual for the radio or imprint, maybe the same issue for the 117?
Why not meet in the middle and get a good 10? I have a JL 10w3 and its been perfect for my systems so far.
My HD 750/1 is at JL getting fixed now, so I cannot comment on my current setup, hopefully by the end of the week though.
