I would really like to run a JL W7 sub and they're far too deep to mount behind the rear seat. I was thinking of having a custom sub box built to sit in front of the factory console. (Upward firing sub)Has anyone ever done this or seen it done. I think I could get a single 10 in that spot...If I moved the console back 1-2" I might be a ble to fit a 12. Any input would be a appreciated.
